                                  THE COMPANY

      The Company is  a major provider of offshore marine  services to the oil
and  gas  exploration  and production  industry  and  is  one of  the  leading
providers of oil  spill response services  to owners of  tank vessels and  oil
storage,  processing  and  handling  facilities.     The  Company  operates  a
diversified  fleet of more than  200 vessels primarily  dedicated to servicing
offshore oil and gas exploration and production facilities in the U.S. Gulf of
Mexico,  the  North  Sea, offshore  West  Africa and  Mexico.    The Company's
offshore   service   vessels  deliver   cargo   and   personnel  to   offshore
installations, handle anchors  for drilling rigs  and other marine  equipment,
support offshore construction and maintenance work and provide  standby safety
support.  The Company also furnishes vessels for special projects such as well
stimulation, seismic data gathering, freight hauling and line handling.

      The  Company's  environmental  services  business  principally  provides
contractual oil spill response services to those who store, transport, produce
or handle petroleum  and certain other non-petroleum  oils as required by  the
Oil  Pollution Act  of 1990  ("OPA 90")  and various  state regulations.   The
Company's  services,  provided primarily  through  its  indirect wholly  owned
subsidiary, National Response  Corporation ("NRC"), include  training for  and
supervision  of  activities  in response  to  oil  spill  emergencies and  the
maintenance of  specialized  equipment  for  immediate  deployment  and  spill
response.   NRC has acted  as the principal  oil spill response  contractor on
several of  the largest oil  spills that  have occurred in  the United  States
since the enactment of OPA 90.

      SEACOR was incorporated in Delaware in  December 1989 for the purpose of
acquiring the  capital stock of NICOR  Marine, Inc. and certain  of its marine
affiliates and  subsidiaries which, at  the time of the  acquisition, owned 36
and  managed five vessels  and to acquire  SCF Offshore, Inc.  which owned two
vessels.

                               1996 DEVELOPMENTS

      On July  3, 1996, the  Company sold in  an underwritten public  offering
909,235 shares of its Common Stock at $43.50 per share  (the "1996 Offering").
In conjunction  with the 1996  Offering, 842,355  shares of Common  Stock were
sold  by  several of  the Company's  stockholders.   The Company  received net
proceeds of  approximately $37.7 million,  of which $26.0 million  was used to
purchase four  out of six vessels  to be acquired from  Compagnie Nationale de
Navigation,  a  French  corporation  ("CNN"), pursuant  to  the  CNN Agreement
described below and to prepay certain indebtedness owed by the  Company to CNN
in connection with prior vessel purchases, and the remainder was allocated for
general corporate purposes.

      On June  6, 1996,  the Company  and CNN entered  into an  agreement (the
"1996  CNN Agreement")  pursuant to  which the  Company agreed to  acquire six
vessels  from CNN  for an  aggregate purchase  price of  $22,650,000 with  the
understanding that three of  such vessels would be bareboat chartered  to CNN.
The  1996 CNN  Agreement  also provided  for  the  Company to  prepay  certain
promissory notes in  the aggregate principal amount of  $9.6 million issued to
CNN by a subsidiary of the Company on December 17, 1993 in connection with the
Company's acquisition  on such date of certain vessels from CNN.  In addition,
CNN agreed to exercise its right to convert $4.75 million  principal amount of
the Company's 2.5%  Convertible Subordinated  Notes due January  1, 2004  (the
"2.5% Notes") issued  to CNN in  connection with such  acquisition of  vessels
into 156,650 shares of Common  Stock in accordance with the terms of  the 2.5%
Notes.   Pursuant to  the 1996  CNN Agreement, the  Company agreed  to include
459,948 shares  of Common Stock owned by CNN on  June 6, 1996, and the 156,650
additional  shares of Common Stock to be  issued to CNN upon the conversion of
the  2.5%  Notes  in  the  1996  Offering  for  resale to  the  public.    The
consummation  of the transactions contemplated  by the 1996  CNN Agreement was
conditioned upon the sale  of such 616,598 shares of Common  Stock in the 1996
Offering and occurred substantially simultaneously with such sale.

<PAGE>
<PAGE>

      On  June 6, 1996, the Company notified First Trust National Association,
as trustee, of the Company's  6.0% Convertible Subordinated Notes due July  1,
2003 (the "6.0% Notes") of  the Company's election to call the  6.0% Notes for
redemption on July 12, 1996.  On or  about July 12, 1996, holders of the  6.0%
Notes converted  the 6.0%  Notes into  shares of  Common Stock  at a ratio  of
39,024 shares  of Common Stock per  $1,000 principal amount of  the 6.0% Notes
(representing   a  conversion  price  of  $25.625  per  share).    The  entire
$55,250,000  principal amount outstanding of the 6.0% Notes were converted and
2,156,083 shares of Common Stock were issued to the holders of the 6.0% Notes.

      On  May  31,  1996,  the  Company   acquired  McCall  Enterprises,  Inc.
("McCall")  and affiliated  companies (collectively,  the  "McCall Companies")
which operate  36 crew boats and  five utility boats dedicated  to serving the
oil  and gas industry primarily in the U.S.  Gulf of Mexico.  Such acquisition
(the "McCall Acquisition") was accomplished pursuant to a series of merger and
share  exchange agreements  (the "McCall  Agreements") involving  the Company,
certain  subsidiaries  of the  Company, the  McCall  Companies and  the former
stockholders  of  the  McCall Companies.    In  consideration  for the  McCall
Acquisition,  on August 9, 1996, the  Company issued an aggregate of 1,306,550
shares  of Common Stock  to the former  stockholders of the  McCall Companies.
The McCall Acquisition is intended to qualify as a tax-free reorganization and
has been accounted for as a pooling-of-interests.

      For additional information relating to the transactions described above,

                                 RISK FACTORS

      PROSPECTIVE  INVESTORS  IN  THE  COMMON  STOCK  OFFERED  HEREBY   SHOULD
CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS, IN ADDITION TO ALL OF THE OTHER
INFORMATION APPEARING OR INCORPORATED BY REFERENCE IN THIS PROSPECTUS.

INDUSTRY CONDITIONS

Offshore Marine Services; Market Volatility

      The Company's offshore  vessel operations are  dependent on activity  in
the offshore oil  and gas exploration and development industry.   The level of
exploration and development of  offshore areas is affected by  both short-term
and long-term trends in oil and gas prices which, in turn, are related  to the
demand  for petroleum  products and  the current availability  of oil  and gas
resources.  The level of  offshore activity is also related to  local policies
that influence drilling activities.  In recent years, oil and  gas prices and,
therefore,  the level of offshore exploration and drilling activity, have been
extremely volatile.   A significant or prolonged decline in future oil and gas
prices  would likely result in reduced exploration and development of offshore
areas and a decline in the demand  for offshore marine services.  Such reduced
activity  could  have a  material adverse  effect  on the  Company's financial
condition and results of operations.

      Charter  rates for  the Company's  equipment also  are dependent  on the
supply of offshore marine vessels.  Excess vessel capacity in the industry can
result  from  refurbishment of  "mothballed"  vessels,  conversion of  vessels
formerly dedicated to  services other  than oil support  and related  offshore
marine  activities,  and construction  of new  vessels.   The addition  of new
capacity  to the worldwide offshore marine fleet would increase competition in
those markets where the Company presently operates which, in turn, could  have
a material  adverse effect on the Company's financial condition and results of
operations.

ENVIRONMENTAL SERVICES

      The environmental  response business is dependent  upon the development,
interpretation and enforcement of regulations promulgated under OPA 90 and, to
a lesser  extent, upon oil spill  response regulations developed at  the state
level.   There  currently  is  no  uniformity  of  regulatory  development  or
enforcement  on  a federal  or  state level.    The Company  believes  that it
generally benefits from increasingly stringent  oil spill regulations and from
increased enforcement  of  such regulations  (which, in  each case,  increases
demand  for NRC's services).  However, a  relaxation of oil spill requirements
or decreased enforcement  of such  regulations could reduce  demand for  NRC's
services  and,  therefore, have  a material  adverse  effect on  the Company's
financial condition and results of operations.

      NRC  is a  "classified" Oil  Spill Removal  Organization ("OSRO").   The
United States Coast Guard  (the"Coast Guard") classifies OSROs based  on their
overall  resource  capability to  respond to  various types  and sizes  of oil
spills  in  different operating  environments  such  as rivers/canals,  inland
waters and oceans (separated  into nearshore, offshore and open  ocean areas).
In  November  1993, shortly  after the  initial  OSRO program  guidelines were
published, NRC applied  for and  received an "E"  classification, the  highest
classification  level  achievable.   Under  the  original  program, NRC's  "E"
classification  expires in 1996 when  it is due for  renewal.  The Coast Guard
reserves the  right to review NRC's  resource capability at any  time based on
the company's performance  during actual response  and cleanup activities  and
exercises  and  may,   under  certain  circumstances,  amend   or  revoke  the
classification.  In  September 1995,  the Coast Guard  proposed revised  draft
OSRO guidelines and requested  industry and regulatory comments.   On December
28, 1995, the revised  OSRO guidelines were published.   Significant revisions
include  geographic-specific  classifications,  a  requirement  to  ensure the
availability of non-dedicated resources  in quantities twice what  is required
of  dedicated resources,  proof  of subcontractor  support and  more stringent
oversight by  the Coast Guard.  NRC has reapplied for new classification under
the
<PAGE>
<PAGE>

revised guidelines.  Although NRC expects to receive an interim classification
in  September  1996,  the  Coast Guard  must  verify  the  information  in the
application,  and there  can be  no assurance  that NRC  will receive  a final
classification   or  a   final  classification   equivalent  to   its  current
classification.

RELIANCE ON SIGNIFICANT CUSTOMERS

      The  Company offers  offshore  marine services  primarily  to the  major
integrated oil companies  and large  independent oil and  gas exploration  and
production  companies.    The  percentage  of   revenues  attributable  to  an
individual customer  varies from time to  time, depending on the  level of oil
and  gas exploration undertaken by  a particular customer,  the suitability of
the Company's vessel for the customer's projection and other factors,  many of
which are beyond the Company's control.  For the year ended December 31, 1995,
approximately  19.5% and 14.8% of the Company's marine operating revenues were
received from Mobil Oil Corporation and Conoco, Inc., respectively.

      The Company  offers its  environmental and  oil spill  response services
primarily to the domestic and international  shipping community, including dry
cargo  vessel owners and owners  of facilities such  as refineries, pipelines,
exploration  and  production  platforms  and  tank  terminals.    The  Company
presently has approximately  325 customers and  provides retainer coverage  to
approximately  1,800 tank  vessels,  850  barges  and  350  facilities.    The
Company's retainer  arrangements with these customers  include both short-term
contracts  (one year or less) and long-term  agreements, in some cases as long
as seven years.   For the  year ended December  31, 1995, Coastal and  Phibro,
NRC's  two largest customers, accounted  for 28.6% of  NRC's retainer revenues
collectively.

GOVERNMENT REGULATION

      Both the Company's offshore marine operations and environmental response
operations are materially  affected by  government regulation in  the form  of
international  conventions,   federal  and  state  laws   and  regulations  in
jurisdictions  where  the Company's  vessels  operate  and/or are  registered.
These  regulations  govern  oil  spills and  other  matters  of  environmental
protection,  worker  health  and safety,  and  the  manning, construction  and
operation of vessels.

      The  Company believes that it  presently is in  material compliance with
the environmental laws and  regulations to which the Company's  operations are
subject.  The  Company is not a party to any pending proceeding and is unaware
of any  threatened litigation or other judicial,  administrative or arbitrable
environmental  proceedings  which,  if  adversely  determined,  would  have  a
material adverse effect on the financial condition or results of operations of
the Company.  However, the risks of incurring substantial compliance costs and
liabilities  and penalties for non-compliance are  inherent in offshore marine
service  operations.    There can  be  no  assurance  that significant  costs,
liabilities,  and penalties will not be incurred  by or imposed on the Company
in the future.

      Offshore Marine Services

      OPA  90 requires owners and operators of  tank vessels and certain other
oil handling facilities to obtain certificates of financial responsibility for
potential  oil  spill  liability.    The  Company  currently   satisfies  this
requirement  with respect  to  the  six  vessels  required  to  maintain  such
certificates.

      Environmental Services

      The  Company's  environmental services  are  conducted  through NRC,  an
indirect wholly owned  subsidiary of the Company.   OPA 90 regulations require
certain  vessels to  identify  in their  response  plans the  availability  of
response resources or OSROs they will use in the event of an oil spill.  NRC's
primary sources of revenue are retainer arrangements with customers for making
available its spill removal vessels and related marine equipment
<PAGE>
<PAGE>

in the event of a spill.  Authority to implement these  regulations is divided
among several regulatory  agencies: the  Coast Guard,  the U.S.  Environmental
Protection  Agency, the  U.S. Minerals  Management Service  and the  Office of
Pipeline  Safety.     Currently,   there  is  no   uniformity  of   regulatory
interpretation  or enforcement  by  these  agencies.    On  the  state  level,
enforcement of analogous regulations varies from  state to state.  Due to this
lack  of  uniformity, the  amount of  response resources  required to  be made
available  to  the  Company's customers  is  unclear.    In addition,  because
regulatory enforcement  initiatives  affect  the  demand  for  NRC's  retainer
coverage, state  and federal regulatory policies may have a material impact on
NRC's results of operations.

      In addition to  establishing policies  which impact the  demand for  and
value  of NRC's  services,  the  Coast  Guard, pursuant  to  its  program  for
classifying  OSROs, provides  classified OSROs  a market  advantage over  non-
classified service providers.   A classified OSRO provides its clients a means
of  verifying that such entity has the necessary response resources available.
Revocation  of such "classification" or changes in the requirements could have
a  material adverse effect on the  Company's financial condition or results of
operations.

      In  providing spill  response services,  NRC is  subject to  the Federal
responder immunity doctrine, otherwise known as the "Good Samaritan" doctrine,
which  holds the Company  harmless from liability  for any  spills that result
from the Company's response efforts, unless the Company is found to be grossly
negligent or to  have engaged in willful  misconduct.  While most  of the U.S.
states in which NRC provides service have adopted the Good Samaritan doctrine,
several states have not.   In the event that  NRC is determined to  have acted
with gross negligence or have engaged in willful misconduct in providing spill
response services,  NRC could be  jointly and severally liable  with the local
contractor and the responsible party for any resulting damages.  Although  NRC
maintains  insurance coverage against such  risks which it considers adequate,
there can  be no  assurance that  such coverage  adequately will cover  future
claims that may arise.

OPERATING RISKS AND INSURANCE

      The  operation of offshore support vessels are subject to various risks,
including catastrophic marine disaster, adverse weather conditions, mechanical
failure,   collision,  oil  and  hazardous  substance  spills  and  errors  of
navigation by vessel  pilots, all of which represent a threat to the safety of
personnel and to  the Company's vessels, cargo, equipment  under tow and other
property, as well as the environment.  The primary operating risks inherent in
the  environmental  response business  are the  failure  to meet  the planning
guidelines of federal  and state  statutes, or gross  negligence in  providing
spill response services.  The occurrence of the foregoing events either in the
offshore marine services  or environmental services  business could result  in
revenue  and casualty loss, increased  costs and significant  liability by the
Company  to third parties.   The Company maintains  insurance coverage against
certain of these risks which it considers adequate, and it has not in the past
experienced a loss  in excess of  policy limits.   There can be  no assurance,
however,  that the  Company's existing  insurance coverage  can be  renewed at
commercially reasonable rates or that such coverage will be adequate to  cover
future claims that may arise.

RELIANCE ON FOREIGN OPERATIONS

      For the year ended December 31, 1995, approximately 37% of the Company's
offshore  marine revenues were derived from foreign operations.  The Company's
foreign  offshore marine operations are  subject to various  risks inherent in
conducting  business in foreign nations.   These risks  include, among others,
political instability, potential vessel seizure and nationalization of assets,
currency restrictions and exchange rate fluctuations, import-export quotas and
other forms of public and governmental regulation, all of which are beyond the
control of the Company.  Although, historically, the Company's operations have
not been materially affected by such  conditions or events, it is not possible
to predict  whether any such conditions or events might develop in the future.
The  occurrence of any one  or more of such conditions  or events could have a
material  adverse effect on the  Company's financial condition  and results of
operations.
<PAGE>
<PAGE>

      The Company  currently operates 30  vessels offshore West  Africa, which
primarily  service the local  offshore oil  and gas  industry.   The Company's
operations offshore West Africa are highly dependent on the level  of activity
in Nigeria.   At this  time, Nigeria,  because of its  domestic policies,  has
become  the   subject  of  certain  international   sanctions,  including  the
suspension of  development aid  by the  European Union  and the  suspension of
Nigeria from the Commonwealth of Nations.  Additional sanctions may be imposed
in the future, which could include economic sanctions, such as an oil embargo.
Economic sanctions or an oil embargo would have a significant negative  impact
on activity in the  oil and gas industry  offshore West Africa, which in  turn
would have a negative impact on the Company's operations  in that area.  There
can be no assurance  that the effects of economic sanctions or  an oil embargo
with  respect  to Nigeria  would not  have a  material  adverse effect  on the
Company's financial condition and results of operations.

CURRENCY FLUCTUATIONS

      Due  to its  foreign  operations, the  Company  is exposed  to  currency
fluctuations and  exchange rate risks.   To minimize  the financial  impact of
these risks, the Company attempts to contract the majority of  its services in
U.S. dollars.   However, in certain  of the Company's  foreign operations, the
Company collects revenues and  pays expenses in local currency.  For financial
statement  reporting purposes these accounts  are translated into U.S. dollars
at the weighted average exchange rates during the relevant period.

      Because the Company  conducts substantially all  its operations in  U.S.
dollars,  to the extent the value of the  U.S. dollar decreases in relation to
the value  of applicable foreign  currencies, such decrease  potentially could
adversely affect the  Company's operating revenues  in foreign  jurisdictions.
To date, currency fluctuations have not had a material impact on the Company's
financial condition or results of operations and the Company is not a party to
any currency hedging arrangements.

AGE OF FLEET

      As of  March 31, 1996 the  average age of the  Company's offshore marine
service fleet was approximately  14 years, whereas, at such  date, the average
age  of the  Company's environmental  service response  fleet was  27.6 years.
NRC's vessels  primarily operate in a  "stand-by" mode with minimal  wear and,
consequently, management does not  consider age to be a reliable  indicator of
the  commercial viability of the vessels.   The Company believes that after an
offshore  supply vessel has  been in service  for approximately 25  years, the
amount of expenditures (which typically increase with vessel age) necessary to
satisfy required  marine  certification  standards  may  not  be  economically
justifiable.   If the Company is unable  to replace its vessels  at the end of
their  useful  economic  lives, the  cost  of  new  building could  materially
increase the  Company's capital expenditures.  There  can be no assurance that
the Company will be able to maintain its fleet by extending the  economic life
of existing  vessels or acquiring new  or used vessels, or  that the Company's
financial   resources  will  be  sufficient  to  enable  it  to  make  capital
expenditures for such purposes.

COMPETITION

      Both the Company's  marine and environmental segments  operate in highly
competitive industries.   In addition  to price, service  and reputation,  the
principal competitive factors for offshore supply fleets include the existence
of national flag  preference, operating  conditions and intended  use (all  of
which determine the  suitability of vessel  types), complexity of  maintaining
logistical support and the cost of  transferring equipment from one market  to
another.

      The principal competitive factors in the environmental services business
are price,  service, reputation, experience  and operating capabilities.   The
Company believes that  the lack  of uniformity of  regulatory development  and
enforcement on a federal and state level has created a lower  barrier of entry
in several market

<PAGE>
<PAGE>

segments which has increased the number of competitors.  NRC faces competition
in several market segments which has increased the number of competitors.  NRC
faces competition  from the Marine  Spill Response  Corporation (a  non-profit
corporation  funded by  the major  integrated  oil companies),  other industry
cooperatives, and  also from  smaller contractors  who target specific  market
niches.

DIVIDENDS

      The  Company has  not paid  any cash  dividends  since its  inception in
December 1989 and presently does not  intend to pay any cash dividends  on its
Common Stock in  the future.  Instead, the Company  intends to retain earnings
for working capital and to  finance the expansion of its business  operations.
In  addition, as  a holding  company, the  Company's ability  to pay  any cash
dividends is  dependent  on  the earnings  and  cash flows  of  its  operating
subsidiaries  and  their  ability to  make  funds  available  to the  Company.
Pursuant  to the  terms of the  DnB Facility,  the Company,  without the prior
written consent of Den norske Bank A/S, is prohibited through January 31, 1996
from paying cash dividends in respect of the Common Stock.

LIMITATION ON FOREIGN OWNERSHIP OF COMMON STOCK

      The  Company is  subject  to the  Shipping Act,  1916,  as amended  (the
"Shipping Act"),  and the Merchant Marine  Act of 1920, as  amended (the "1920
Act," and collectively with the Shipping Act, the "Acts"), which govern, among
other things,  the ownership  and operation  of  vessels used  to carry  cargo
between  U.S. ports.    The Acts  require  that vessels  engaged  in the  U.S.
coastwise trade be (i)  owned by U.S. citizens and (ii) built in the U.S.  For
a corporation engaged in  the U.S. coastwise trade  to be deemed a  citizen of
the U.S., (a) the corporation must be  organized under the laws of the U.S. or
of a  state, territory or  possession thereof,  (b) each of  the president  or
other chief  executive officer and the  chairman of the board  of directors of
such corporation must be  U.S. citizens, (c)  no more than  a minority of  the
number of directors  of such corporation necessary to constitute  a quorum for
the transaction  of business can be non-U.S. citizens and  (d) at least 75% of
the interest in such corporation must  be owned by U.S. "Citizens" (as defined
in  the Acts).   Should the Company  fail to comply with  the U.S. citizenship
requirements of the Acts, it would be prohibited from operating its vessels in
the U.S. coastwise trade during the period of such non-compliance.

      To  facilitate   compliance  with  the  Acts,   the  Company's  Restated
Certificate of  Incorporation: (i) contains provisions  limiting the aggregate
percentage ownership by Foreigners of any class of the Company's capital stock
(including  the Common Stock) to 22.5% of  the outstanding shares of each such
class  to ensure  that  such foreign  ownership will  not  exceed the  maximum
percentage  permitted  by  applicable  maritime  law  (presently  25.0%),  and
authorizes the Board  of Directors, under  certain circumstances, to  increase
the foregoing percentage to  24.0%, (ii) requires institution of  a dual stock
certification  system to help determine  such ownership and  (iii) permits the
Board of Directors to make such  determinations as reasonably may be necessary
to ascertain such ownership and implement such  limitations.  In addition, the
Company's  By-laws  provide that  the number  of  foreign directors  shall not
exceed  a minority  of the  number necessary  to constitute  a quorum  for the
transaction of  business and restrict  any officer who  is not a  U.S. citizen
from acting in  the absence  or disability  of the  Chairman of  the Board  of
Directors  and Chief Executive Officer and the  President, all of whom must be
U.S. citizens.   At September 3, 1996, less  than 1% of the outstanding Common
Stock was owned by Foreigners.

                                DIVIDEND POLICY

      SEACOR  has not  paid  any cash  dividends  since its  incorporation  in
December  1989.   SEACOR  presently intends  to  retain earnings  for  working
capital and to finance the expansion of the Company's business operations and,
therefore, does not  intend to pay cash  dividends on the Common  Stock in the
foreseeable  future.  In addition,  as a holding  company, SEACOR's ability to
pay dividends  is strictly dependent  on the  earnings and cash  flows of  its
operating  subsidiaries and  their  ability to  make  funds available  to  the
Company and is further restricted by the terms of the DnB Facility.  See "Risk
Factors-Dividends."

      The payment  of future cash dividends,  if any, would be  made only from
assets  legally available  therefor, and  would also  depend on  the Company's
financial condition, results  of operations, current  and anticipated  capital
requirements,   plans  for   expansion,   restrictions  under   then  existing
indebtedness  and other factors deemed relevant by SEACOR's Board of Directors
in its sole discretion.

                             SELLING STOCKHOLDERS

      In connection with the McCall Acquisition, on May 31, 1996,  the Company
entered into an investment  and registration rights agreement with  the former
stockholders of the  McCall Companies (the  "Selling Stockholders") listed  on
the signature  pages thereto  (the  "McCall Registration  Rights  Agreement").
Pursuant to the McCall  Registration Rights Agreement, the Company  has agreed
to  bear  certain  expenses related  thereto  and  to  indemnify each  Selling
Stockholder against  certain liabilities, including liabilities  arising under
the federal  securities laws.  The Company has filed with the Commission under
the  Securities Act, the Registration Statement of which this Prospectus forms
a part with respect to the sale by the Selling Stockholders of the Shares from
time to  time  on the  NASDAQ  National  Market (or  any  national  securities
exchange  or  U.S. automated  inter-dealer  quotation system  of  a registered
national securities  association on which  the shares are  then listed) or  in
privately negotiated transactions, and has agreed  to use its best efforts  to
keep the Registration Statement current and effective through September  1998,
subject to extension  in certain  circumstances, or such  shorter period  that
will terminate when all the shares covered by the  Registration Statement have
been sold.

                             PLAN OF DISTRIBUTION

      The Selling Stockholders have advised the Company that the Shares may be
sold from time to time  by the Selling Stockholders, or their  transferees, on
the  NASDAQ National  Market  (or any  national  securities exchange  or  U.S.
automated  interdealer quotation  system of  a registered  national securities
association on which shares of Common Stock are then listed), or in negotiated
transactions or  otherwise.  The  Shares will be sold  at prices and  on terms
then prevailing,  at prices  related to the  then-current market price  of the
Shares,  or  at negotiated  prices.   The Company  has  been advised  that the
Selling Stockholders may effect sales of the Shares directly, or indirectly by
or through agents or broker-dealers and that  the Shares may be sold by one or
more  of  the following  methods:   (a)  ordinary brokerage  transactions, (b)
purchases by a broker-dealer as principal and resale by such broker-dealer for
its  own  account,  and (c)  in  "block" sale  transactions.   At  the  time a
particular  offer is  made,  a Prospectus  Supplement,  if required,  will  be
distributed that sets forth the name or names of agents or broker-dealers, any
commissions and  other terms constituting  selling compensation and  any other
required information.  Moreover, in effecting sales, broker-dealers engaged by
any Selling Stockholder  and/or the purchasers of  the Shares may  arrange for
other  broker-dealers to participate in the sale process.  Broker-dealers will
receive discounts  or  commissions from  the  Selling Stockholder  and/or  the
purchasers of the Shares in amounts which will be negotiated prior to the time
of sale.  Sales will be made only through broker-dealers registered as such in
a subject  jurisdiction or in transactions exempt from such registration.  The
Company has not been advised of any definitive selling arrangement at the date
of  this Prospectus between any  Selling Stockholder and  any broker-dealer or
agent.

      In  connection  with  the  distribution  of  the  Shares,   the  Selling
Stockholders  may enter  into hedging  transactions  with broker-dealers.   In
connection with such transactions, broker-dealers may engage in short sales of
the Shares in the course of hedging the positions they assume with the Selling
Stockholders.   The Selling Stockholders  may also sell  the Shares  short and
redeliver  the  Shares  to  close  out  the  short  positions.    The  Selling
Stockholders may also  enter into  option or other  transactions with  broker-
dealers which  require the delivery to  the broker-dealer of the  Shares.  The
Selling Stockholders may also loan or pledge the Shares to a broker-dealer and
the broker-dealer may sell the  Shares so loaned or upon a default the broker-
dealer may effect sales of the pledged shares.

      Any  broker or  dealer participating  in any  distribution of  Shares in
connection with  the offering made hereby may be deemed to be an "underwriter"
within the meaning of the Securities Act and may be required to deliver a copy
of  this  Prospectus, including  a Prospectus  Supplement,  to any  person who
purchases any of the Shares from or through such broker or dealer.

      The  Company is required under the  McCall Registration Rights Agreement
to comply  with the requirements of  Rule 144(c) under the  Securities Act, as
such Rule may be amended from time to time (or any

<PAGE>
<PAGE>

similar rule or regulation hereafter adopted by the Commission), regarding the
availability  of current public information  to the extent  required to enable
the  Selling  Stockholders  to  sell  Shares  without  registration under  the
Securities Act pursuant to Rule 144 (or any similar rule or regulation).

      Pursuant to  the McCall Registration  Rights Agreement, all  expenses of
registration of the Shares will be paid  by the Company, including, Commission
filing fees,  and expenses of  compliance with state securities  or "blue sky"
laws.   The Selling  Stockholders will be  indemnified by the  Company against
certain  civil liabilities,  including certain  liabilities arising  under the
Securities  Act,  or, to  the extent  such  indemnification is  unavailable or
otherwise  limited, will be entitled to  contribution in connection therewith.
The Company will not receive any  of the proceeds from the sale of  the Shares
by the Selling Stockholders.

                                 LEGAL MATTERS

      The legality  of the securities  offered hereby will be  passed upon for
the Company by Weil, Gotshal & Manges LLP.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

      (1)   As more fully  described below,  Section 145 of  the DGCL  permits
Delaware  corporations to indemnify each of their present and former directors
or officers under certain  circumstances, provided that such persons  acted in
good  faith and in a  manner which they  reasonably believed to be  in, or not
opposed to, the best interests  of the corporation.  Article Eight  of the By-
laws  provides that  the  Company  shall  indemnify,  to  the  fullest  extent
permitted by Section 145  of the DGCL, as the same may be amended from time to
time, all persons whom it may indemnify pursuant thereto.

      Specifically,  Section 145 of the  DGCL provides that  a corporation may
indemnify any person who was or is a party or is threatened to be made a party
to  any threatened, pending or  completed action, suit  or proceeding, whether
civil, criminal, administrative or  investigative (other than an action  by or
in the  right of the corporation)  by reason of the  fact that he is  or was a
director, officer, employee, or agent of the corporation, or is or was serving
at the request of the  corporation as a director, officer, employee,  or agent
of another corporation,  partnership, joint venture, trust or other enterprise
against  expenses (including  attorneys' fees),  judgments, fines  and amounts
paid in  settlement actually and reasonably incurred by him in connection with
such action, suit, or proceeding if he acted in  good faith and in a manner he
reasonably believed  to be in  or not  opposed to  the best  interests of  the
corporation,  and, with respect  to any criminal action  or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The  termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon
plea of  nolo contendere or  its equivalent,  shall not, of  itself, create  a
presumption that the person did not act in good faith and in a manner which he
reasonably believed  to be  in or  not opposed to  the best  interests of  the
corporation, or,  with respect to  any criminal action or  proceeding, that he
had reasonable cause to believe that his conduct was unlawful.

      Section  145 of the DGCL also provides  that a corporation may indemnify
any person  who was or is a  party or is threatened to be  made a party to any
threatened, pending, or  completed action or suit  by or in  the right of  the
corporation to procure a  judgment in its favor by reason of  the fact that he
is or was a director, officer, employee, or agent of the corporation, or is or
was  serving  at  the  request  of the  corporation  as  a  director, officer,
employee, or agent of another corporation or is or was serving at  the request
of  the  corporation as  a  director, officer,  employee or  agent  of another
corporation,  partnership, joint  venture, trust  or other  enterprise against
expenses (including attorneys'  fees) actually and reasonably  incurred by him
in connection  with the  defense or settlement  of such action  or suit  if he
acted  in good faith and  in a manner  he reasonably believed to  be in or not
opposed  to  the  best  interests  of  the  corporation  and  except  that  no
indemnification shall be made in  respect of any claim, issue or  matter as to
which such  person shall have  been adjudged to  be liable to  the corporation
unless and

                                      II-1

<PAGE>
<PAGE>
     

only to  the extent that  the Court  of Chancery  or the court  in which  such
action or suit was brought shall determine upon adjudication that, despite the
adjudication of  liability but in view  of all the circumstances  of the case,
such person is fairly  and reasonably entitled to indemnity  for such expenses
which the Court of Chancery or such other court shall deem proper.

      Any such indemnification  (unless ordered by a  court) shall be made  by
the  corporation only as authorized in  the specific case upon a determination
that indemnification of the director, officer, employee or agent is proper  in
the  circumstances  because such  person has  met  the applicable  standard of
conduct set forth above.

      Section  145  of the  DGCL permits  a  Delaware business  corporation to
purchase and  maintain insurance  on  behalf of  any person  who is  or was  a
director, officer, employee or agent of  the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another  corporation, partnership,  joint venture,  trust or  other enterprise
against any liability asserted against such  person and incurred by him in any
such  capacity, or  arising  out of  his status  as such,  whether or  not the
corporation would have the power to indemnify such person.

      (2)    Section 102(b)  of the  DGCL  enables a  Delaware  corporation to
include  a provision in its certificate of incorporation limiting a director's
liability  to the  corporation or  its stockholders  for monetary  damages for
breaches of fiduciary  duty as a  director.  The Certificate  of Incorporation
contains  provisions that limit the personal liability of each director to the
Registrant  or its  stockholders  for  monetary  damages  for  breach  of  the
fiduciary duty  of care as  a director.   These provisions  eliminate personal
liability to the fullest extent permitted by the DGCL.

ITEM 17.  UNDERTAKINGS

(a)  The undersigned registrant hereby undertakes:

           (1)   To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

                        (iii)    To  include  any  material  information  with
                  respect to the plan of distribution not previously disclosed
                  in the registration statement or any material change to such
                  information in the registration statement;

           (2)  That, for  the purpose of determining any liability  under the
      Securities Act,  each such post-effective amendment  shall be  deemed to
      be  a new  registration  statement relating  to the  securities  offered


                                      II-4
<PAGE>
<PAGE>


      therein,  and the  offering of  such securities  at that  time shall  be
      deemed to be the initial bona fide offering thereof.

           (3)    To remove  from registration  by  means of  a post-effective
amendment  any of the  securities being registered which  remain unsold at the
termination of the offering.

(b)    The  undersigned registrant  hereby undertakes  that,  for purposes  of
determining  any  liability  under the  Securities  Act,  each  filing of  the
registrant's annual report pursuant  to Section 13(a) or Section 15(d)  of the
Exchange Act that is  incorporated by reference in the  registration statement
shall be deemed to be a  new registration statement relating to the securities
offered  therein, and the  offering of such  securities at that  time shall be
deemed to be the initial bona fide offering thereof.

(e)   The undersigned registrant hereby undertakes to deliver or cause  to be
delivered  with the prospectus, to each person  to whom the prospectus is sent
or given, the latest  annual report, to security holders  that is incorporated
by reference  in the  prospectus and  furnished pursuant  to  and meeting  the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities  Exchange Act of
1934; and, where  interim financial  information required to  be presented  by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom  the prospectus is sent or given,
the  latest quarterly report that is specifically incorporated by reference in
the Prospectus to provide such interim financial information.

(h)   Insofar as indemnification for liabilities  arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the  registrant  pursuant  to  the  foregoing  provisions,  or  otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is  against public policy as expressed  in the
Act  and is,  therefore,  unenforceable.    In  the event  that  a  claim  for
indemnification against  such  liabilities  (other  than the  payment  by  the
registrant of expenses incurred or paid by a director, officer or  controlling
person  of the  registrant in the  successful defense  of any  action, suit or
proceeding) is asserted  by such  director, officer or  controlling person  in
connection with the securities being  registered, the registrant will,  unless
in  the opinion  of its  counsel the  matter has  been settled  by controlling
precedent,  submit to a court of appropriate jurisdiction the question whether
such indemnification  by it is against  public policy as expressed  in the Act
and will be governed by the final adjudication of such issue.

The Board of Directors
SEACOR Holdings, Inc. 
11200 Westheimer 
Suite 850 
Houston, TX  77042

Ladies and Gentlemen:

            We  have acted  as counsel  to SEACOR  Holdings, Inc.,  a Delaware
corporation (the "Company"), in connection with the  preparation and filing of
the Registration Statement of the Company on Form S-3 (the "Registration
Statement")  under the  Securities Act  of 1933,  as amended  (the "Securities
Act"),  relating  to the  intended resale  from time  to  time by  the Selling
Stockholders  (in the  manner described in  the prospectus  (the "Prospectus")
contained  in the Registration Statement)  of up to  an aggregate of 1,176,646
shares of Common Stock, $.01 par value (the "Common Stock"), of the Company.

            In  so  acting,  we  have  reviewed  the  Registration  Statement,
including  the Prospectus contained  therein, and the  Restated Certificate of
Incorporation and the Bylaws of the Company in effect  on the date hereof.  In
addition,  we  have  examined  originals or  copies,  certified  or  otherwise
identified  to  our  satisfaction,  of  such  corporate  records,  agreements,
documents and other instruments, and such certificates or comparable documents
of  public officials and  of officers and representatives  of the Company, and
have  made such  inquiries of such  officers and  representatives, as  we have
deemed  relevant and  necessary as  a basis for  the opinions  hereinafter set
forth.

            In such  examination,  we  have assumed  the  genuineness  of  all
signatures,  the legal capacity  of natural  persons, the authenticity  of all
documents submitted to us as  originals, the conformity to original  documents
of all  documents submitted to us  as certified or photostatic  copies and the
authenticity of the  originals of such latter documents.   As to all questions
of fact material to this opinion that have not been independently established,
we have  relied  upon certificates  or comparable  documents  of officers  and
representatives of the Company.

            Based  on the foregoing, and  subject to the qualifications stated
herein, we are of the opinion that:

            1.    The Company  is a corporation duly  incorporated and validly
existing under the laws of the State of Delaware.

            2.    The  shares  of  Common  Stock to  be  sold  by  the Selling
Stockholders in the manner described under the captions "Selling Stockholders"
and  "Plan of Distribution"  in the  Prospectus contained in  the Registration
Statement have been validly issued and fully paid for and are nonassessable.
