                               Chairman's Message

DEAR FELLOW SHAREHOLDERS:
The Taxpayer  Relief Act of 1997 recently  signed into law by President  Clinton
includes new twists and important changes to Individual Retirement Account (IRA)
laws. The provisions will, among other things,  allow more people to qualify for
annual  tax-deductible IRA contributions and to save tax-free for college.  They
also allow IRA investors to withdraw money  penalty-free  from all IRAs to buy a
first home or pay for college expenses.

     For existing  deductible  IRAs, the law doubles income limits over the next
eight to 10 years for those eligible to deduct an annual IRA  contribution of up
to $2,000.  For individuals,  the annual income cap will increase  incrementally
from the  current  $25,000 to  $50,000 by 2005.  For  couples,  the limit  would
increase from $40,000 today to $80,000 in 2007.  The new law allows  non-working
spouses to make IRA  contributions  even if their spouse is covered by a pension
plan at work, provided the couple's joint income is less than $150,000.

[A 1 1/4" x 1" photo of Edward J. Boudreau,  Jr.,  Chairman and Chief  Executive
Officer, flush right, next to second paragraph.]

     The law also creates two new IRA investment vehicles. One, called the "Roth
IRA" after its principal congressional sponsor, allows for non-deductible annual
contributions up to a $2,000 maximum. But income accumulates tax-free and if the
account has been open for five  years,  distributions  are  tax-free if they are
used after age 591/2 or upon death,  disability or a first-time  home  purchase.
Withdrawals for higher-education expenses would not be subject to a 10% penalty.
Eligible investors must earn less than $95,000 per year individually or $150,000
per couple.

     A second new IRA plan,  called the "Education  IRA," allows  non-deductible
contributions  of up to $500 per year,  per child under age 18.  Earnings in the
account  accumulate  tax-free,  and  withdrawals are also not taxed when applied
toward undergraduate or graduate-level expenses.  Eligible investors are subject
to the same income restrictions that apply to the Roth IRA.

     The law has also made some important changes in capital gains tax rates and
estate tax laws. But the devil is in the details,  and so we recommend exploring
how you can benefit from the changes with your investment  professional  and tax
advisor.  The Taxpayer  Relief Act of 1997 gives  investors  new options  toward
savings. It's a move we applaud.

Sincerely,

/s/ Edward J. Boudreau, Jr.

                            Premium Dividend Fund I

                Utility stocks powered by favorable bond market,
                ------------------------------------------------
                             regulatory environment
                             ----------------------


Utility  stocks -- which are the primary focus of John Hancock  Patriot  Premium
Dividend  Fund I -- were boosted by the twin engines of a strong bond market and
a more  favorable  regulatory  environment  over the past 12 months.  Because of
their high yields,  utility stocks tend to closely follow the bond market, which
was a bit shaky at first but ended the period  with a full head of steam.  After
shrugging  off several bouts of  nervousness  earlier this year over whether the
economy was growing fast enough to whip up inflation, investors sent bond prices
higher and bond yields lower throughout most of the summer and fall.

     While  the  bond  market's  success  was the main  key to  utility  stocks'
performance,  there were also others.  First, August 1997 was the stock market's
worst month in several  years.  In a classic  "flight to safety," some investors
fled from high-flying growth stocks into high dividend-yielding  stocks, such as
utility stocks, as a way to guard against the vagaries of a weaker stock market.
In the meantime,  the regulatory environment showed signs of turning in favor of
the utilities themselves.  Some areas of the country appear to be leaning toward
adopting California's and Massachusetts' model of allowing competition. In those
states,  electric  utilities will be allowed to recoup expenses -- incurred at a
time when  utilities  were  monopolies  -- in a manner  that will  allow them to
compete

"...the  regulatory  environment  showed  signs  of  turning  in  favor  of  the
utilities..."

[Pie  chart with the  heading  "Portfolio  Diversification"  at top of left hand
column.  The chart is divided into five sections.  Going from top left to right:
Short-term  Investments & Other 1%; Common Stock Utilities 21%;  Preferred Stock
Utilities 47%;  Financials 18%;  Industrials  13%. A footnote below states "As a

effectively  with  out-of-state  providers.  Additionally,  the  Federal  Energy
Regulatory  Commission and various state  electric  utility  agencies  quickened
their response to proposed mergers among utilities.

Performance and strategy recap 
For the year ended  September 30, 1997, the Fund had a total return of 18.60% at
net asset value. By comparison, the Dow Jones Utility Average had a total return
of 15.46% and the average  preferred  stock  closed-end  fund  returned  18.68%,
according  to  Lipper  Analytical  Services,  Inc.  Throughout  the past year we
maintained  a  defensive  stance,  but  became  a bit  less so by the end of the
period.  Preferred-stock holdings, which made up 78% of net assets at the end of
the  period,  offer  above-average  yields.  Because  of that,  they are a great
defense against rising interest rates, and generally weathered the bond market's
volatility  better  than  common  stocks.  Of our  preferred  holdings,  roughly
three-quarters  were securities  eligible for the  dividends-received  deduction
(DRD), which offer distinct tax advantages to corporate investors. The prices of
DRD-eligible  securities  were driven  higher  because  supply is shrinking  and
demand has been unusually strong.

left  column  is  "Investments";  the  header  for the right  column is  "Recent
performance  ... and what's  behind the  numbers."  The first listing is Montana
Power  Company  followed by an up arrow and the phrase  "Enters  agreement  with
telecom providers." The second listing is Florida Progress  Corporation followed
by an up arrow and the phrase "Rebounded from nuclear plant problems." The third
listing is Commonwealth  Edison Company  followed by a horizontal  arrow and the
phrase  "Concerns  about  nuclear  plant  safety."  Footnote  below reads:  "See
"Schedule of Investments." Investment holdings are subject to change."]

     Despite our  continued  emphasis on preferred  stocks,  we made a conscious
effort to add more  high-yielding  utility common stocks because we thought they
were exceptionally cheap,  particularly in April, July, and August. When some of
the Fund's higher-yielding  preferred stocks were called out of the market -- or
redeemed -- by their issuers, we looked for  attractively-priced,  high-yielding
stocks to replace them. In many cases,  utility common stocks were not only more
attractively-priced  than their preferred  DRD-eligible  counterparts,  but they
also offered higher yields. By the end of the period, utility common stocks made
up 21% of the Fund's net assets, compared to 14% six months earlier.

Winners and losers 
During the  period,  one of our best  performers  was Boston  Edison,  which was
boosted by favorable  and  improving  regulatory  conditions  in  Massachusetts.
Likewise,  neighboring New England Electric System benefited from that trend, as
well as from its sale of non-nuclear power plants at favorable  prices.  Another
solid performer was Montana Power, one of the lowest-cost  electric providers in
the United States,  which was boosted in part on the news of its partnering with
Enron and Williams Companies in a telecommunications joint venture to build

[Bar chart with heading "Fund Performance" at top of left hand column. Under the
heading is the  footnote:  For the year ended  September 30, 1997." The chart is
scaled in increments of 5% with 20% at the top and 0% at the bottom.  Within the
chart there are three solid bars.  The first  represents the 18.60% total return
for the John Hancock Patriot Premium Dividend Fund I. The second  represents the
18.68% total return for the Average  preffered stock  closed-end fund. The third
represents the 15.46% total return for the Dow Jones Utility Average. A footnote
below states: "The total return for John Hancock Patriot Premium Dividend Fund I

fiber optic networks. Florida Progress Corporation also posted attractive gains,
after tumbling  earlier when it was forced to close its nuclear plant. We bought
the stock after the problems  surfaced because its price cheapened to a level we
felt was  attractive,  given  the  company's  commitment  to a  relatively  high
dividend,  its strong  balance  sheet,  its strong  service  territory,  and the
favorable  regulatory  environment  in  Florida.  More  recently,  the  NRC  has
applauded the utility's  progress in cleaning up its nuclear site,  which helped
the stock  stage a  rebound.  Finally,  we  enjoyed  good  performance  from IES
Industries,  which announced its participation in a three-party electric company
merger.

     Outside the utility  sector,  we saw solid  performance  from our financial
stocks.  The price of Salomon Inc.'s preferred stock, for example,  rose on news
that it planned to merge with insurance giant Travelers.

     Like any other time  period,  this one had a few  disappointments.  One was
electric provider  Commonwealth  Edison,  which serves the Chicago  metropolitan
area.  Concerns  about the safety of its nuclear  plants,  its  relatively  high
costs,  and a  less-than-favorable  regulatory  environment in Illinois kept the
credit under pressure.

"Our outlook is reasonably optimistic."

Outlook
Our outlook is  reasonably  optimistic.  Recent  developments  suggest  that the
economy  may be  slowing.  One  implication  of that  slowing  is that it likely
eliminates the impetus for the Federal  Reserve Board to raise  interest  rates.
Stable interest  rates, of course,  would be a positive for the bond market and,
ultimately, for preferred and utility stocks.  Additionally, a weakening economy
could translate into lower corporate earnings. If that is the case, we could see
more buying of utility stocks,  which are viewed as immune to the economy's ebbs
and flows.  As far as electric  utility  stocks go, we think their recent strong
performance  could be extended.  We've already seen evidence that the regulatory
environment  has  improved  and  merger   activity  is  quickening.   There's  a
possibility  that the Public  Utility  Holding  Company Act of 1935 -- which has
slowed merger activity -- will be repealed next year. If that law is eliminated,
we're likely to see the rate of utility company consolidation  quicken, aided by
purchases from oil companies and foreign buyers.

              John Hancock Funds - Patriot Premium Dividend Fund I


NOTE A --
ACCOUNTING POLICIES
Patriot  Premium  Dividend  Fund  I (the  "Fund")  is a  diversified  closed-end
management  investment  company,  registered under the Investment Company Act of
1940, as amended.  Significant  accounting  policies of the Fund are as follows:

VALUATION OF  INVESTMENTS  Securities in the Fund's  portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services,
or at fair value as  determined  in good  faith in  accordance  with  procedures
approved by the Trustees.  Short-term debt  investments  maturing within 60 days
are valued at amortized cost which approximates market value.

INVESTMENT  TRANSACTIONS  Investment transactions are recorded as of the date of
purchase,  sale  or  maturity.  Net  realized  gains  and  losses  on  sales  of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies, and
to  distribute  all of its taxable  income,  including  any net realized gain on
investments, to its shareholders.  Therefore, no federal income tax provision is
required.  For federal income tax purposes, the Fund has $1,225,714 of a capital
loss carryforward  available,  to the extent provided by regulations,  to offset
future net realized capital gains. If such  carryforward is used by the Fund, no
capital gains distributions will be made. The carryforward  expires on September
30, 2003.  Additionally,  net capital losses of $2,399  attributable to security
transactions incurred after October 31, 1996 are treated as arising on the first
day (October 1, 1997) of the Fund's next taxable year.

DIVIDENDS,  INTEREST AND DISTRIBUTIONS  Dividend income on investment securities
is recorded on the ex-dividend date. Interest income on investment securities is
recorded on the accrual basis.

     The Fund records all dividends and  distributions to shareholders  from net
investment income and realized gains on the ex-dividend date. Such distributions
are  determined  in  conformity  with  federal  income tax  regulations.  Due to
permanent book/tax differences in accounting for certain transactions,  this has
the potential for treating certain distributions as return of capital as opposed
to  distributions  of net investment  income or realized capital gains. The Fund
has adjusted for the cumulative  effect of such permanent  book/tax  differences
through  September 30, 1997,  which has no effect on the Fund's net assets,  net
investment income or net realized gains.

USE OF ESTIMATES The  preparation  of these  financial  statements in accordance
with generally accepted  accounting  principles  incorporates  estimates made by
management in determining the reported amounts of assets, liabilities, revenues,
and expenses of the Fund. Actual results could differ from these estimates.

DUTCH AUCTION RATE TRANSFERABLE  SECURITIES PREFERRED STOCK SERIES A (DARTS) The
Fund issued 685 shares of Dutch Auction Rate Transferable  Securities  Preferred
Stock Series A (DARTS)  concurrently  with the issuance of its Common  Shares in
the public offering.  The  underwriting  discount was recorded as a reduction of
the capital of the Common  Shares.  Dividends on the DARTS,  which accrue daily,
are cumulative at a rate which was  established at the offering of the DARTS and
have been reset every 49 days thereafter by auction.  Dividend rates ranged from
3.86% to 4.25% during the year ended September 30, 1997.

     The DARTS are  redeemable  at the option of the Fund at a redemption  price
equal to  $100,000  per share  plus  accumulated  and  unpaid  dividends  on any
dividend  payment date. The DARTS are also subject to mandatory  redemption at a
redemption  price  equal to  $100,000  per share,  plus  accumulated  and unpaid
dividends,  if the Fund is in default on its asset  coverage  requirements  with
respect to the DARTS.  If the  dividend on the DARTS shall  remain  unpaid in an
amount equal to two full years' dividends, the holders of the DARTS, as a class,
have the right to elect a majority of the Board of  Trustees.  In  general,  the
holders of the DARTS and the Common  Shares have equal voting rights of one vote
per share,  except that the holders of the DARTS, as a class,  vote to elect two
members of the Board of  Trustees,  and  separate  class  votes are  required on
certain  matters  that affect the  respective  interests of the DARTS and Common
Shares.  The DARTS have a  liquidation  preference  of $100,000 per share,  plus
accumulated and unpaid dividends. The Fund is required to maintain certain asset
coverage with respects to the DARTS, as defined in the Fund's By-Laws.

              John Hancock Funds - Patriot Premium Dividend Fund I


NOTE B -- 
MANAGEMENT FEE AND TRANSACTIONS WITH AFFILIATES 
AND OTHERS  
Under the investment management contract, the Fund pays a monthly management fee
to John Hancock Advisers, Inc. (the "Adviser"), a wholly owned subsidiary of The
Berkeley Financial Group, for a continuous investment program equivalent,  on an
annual basis, to the sum of 0.50% of the Fund's average weekly net assets,  plus
5% of the Fund's  weekly gross income.  The Adviser's  total fee is limited to a
maximum  amount equal to 1.00% annually of the Fund's average weekly net assets.
For the period  ended  September  30,  1997,  the  advisory fee incurred did not
exceed the maximum advisory fee allowed.

     The Fund has  entered  into an  administrative  agreement  with the Adviser
under which the Adviser oversees the custodial, auditing, valuation, accounting,
legal,  stock  transfer,  and dividend  disbursing  services and maintains  Fund
communications  services with the  shareholders.  The Adviser receives a monthly
administration  fee  equivalent,  on an  annual  basis,  to 0.10% of the  Fund's
average weekly net assets.

     Each  unaffiliated  Trustee is  entitled,  as  compensation  for his or her
services, to an annual fee plus remuneration for attendance at various meetings.

     Mr.  Edward J.  Boudreau,  Jr.,  Ms.  Anne C.  Hodsdon  and Mr.  Richard S.
Scipione are directors and/or officers of the Adviser and/or its affiliates,  as
well as Trustees of the Fund. The compensation of unaffiliated Trustees is borne
by the Fund. The unaffiliated Trustees may elect to defer for tax purposes their
receipt of this  compensation  under the John  Hancock  Group of Funds  Deferred
Compensation  Plan. The Fund makes investments into other John Hancock Funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's  deferred  compensation  liability  are  recorded on the Fund's
books as an other asset. The deferred compensation  liability and the investment
to cover the  liability  are  marked to market on a  periodic  basis to  reflect
income earned by the  investment and income earned by the investment is recorded
on the Fund's books.  At September 30, 1997, the Fund's  investment to cover the
deferred compensation liability had unrealized appreciation of $2,192.

NOTE C --
INVESTMENT TRANSACTIONS 
Purchases and proceeds from sales of securities,  other than  obligations of the
U.S.  government  and its agencies and  short-term  securities,  during the year
ended   September   30,  1997,   aggregated   $119,115,005   and   $116,368,267,
respectively.  There  were no  purchases  or  sales of  obligations  of the U.S.
government and its agencies during the year ended September 30, 1997.

     The cost of long-term  investments  owned at September 30, 1997 for federal
income  tax  purposes  was  $205,004,901.   Gross  unrealized  appreciation  and
depreciation of investments aggregated $11,321,778 and $1,660,095, respectively,
resulting in net unrealized appreciation of $9,661,683 for federal tax purposes.

NOTE D -- 
RECLASSIFICATION OF ACCOUNTS 
During the year ended September 30, 1997, the Fund has  reclassified  amounts to
reflect an increase in accumulated net realized loss on investments of $174,436,
an increase in undistributed net investment income of $179,774 and a decrease in
capital paid-in of $5,338.  This represents the amount necessary to report these
balances  on a  tax  basis,  excluding  certain  temporary  differences,  as  of
September 30, 1997. Additional adjustments may be needed in subsequent reporting
periods. These reclassifications, which have no impact on the net asset value of
the Fund, are primarily  attributable to certain  differences in the computation
of  distributable  income and  capital  gains  under  federal  tax rules  versus
generally  accepted  accounting  principles.  The  calculation of net investment
income per share in the financial highlights excludes these adjustments.

INDEPENDENT AUDITORS' REPORT
To the  Shareholders  and Board of  Trustees  of John  Hancock  Patriot  Premium
Dividend Fund I:

We have audited the  accompanying  statement of assets and  liabilities  of John
Hancock  Patriot Premium  Dividend Fund I (the Fund),  including the schedule of
investments,  as of September 30, 1997, the related statements of operations and
changes in net assets,  and financial  highlights for the year then ended. These
financial  statements  and financial  highlights are the  responsibility  of the
Fund's  management.  Our  responsibility  is to  express  an  opinion  on  these
financial  statements and financial highlights based on our audit. The financial
statements  of the Fund for the year ended  September 30, 1996 and the financial
highlights  for the four years then ended were audited by other  auditors  whose
report,  dated  November  1, 1996,  expressed  an  unqualified  opinion on those
statements.

     We conducted  our audit in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
September 30, 1997 by correspondence with the custodian.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

     In our opinion,  such financial statements and financial highlights present
fairly,  in all  material  respects,  the  financial  position of the Fund as of
September  30,  1997,  the  results of its  operations,  the  changes in its net
assets, and its financial  highlights for the year then ended in conformity with
generally accepted accounting principles.

              John Hancock Funds - Patriot Premium Dividend Fund I


INVESTMENT OBJECTIVE AND POLICY
The Fund's  investment  objective is to provide high current income,  consistent
with modest  growth of capital for holders of its Common  Shares.  The Fund will
pursue its objective by investing in a diversified  portfolio of dividend-paying
preferred  and common equity  securities.  

DIVIDEND REINVESTMENT PLAN   
The Fund provides  shareholders with a Dividend  Reinvestment Plan ("the Plan"),
which offers the  opportunity to earn compounded  yields.  Each holder of Common
Shares will  automatically have all distributions of dividends and capital gains
reinvested by State Street Bank and Trust Company, 225 Franklin Street,  Boston,
Massachusetts, 02210, as agent for the common shareholders unless an election is
made to receive cash.  Holders of Common Shares who elect not to  participate in
the Plan will receive all distributions in cash, paid by check,  mailed directly
to the  shareholder  of record  (or if the  Common  Shares are held in street or
other  nominee  name  then  to the  nominee)  by the  Plan  Agent,  as  dividend
disbursing agent.  Shareholders whose shares are held in the name of a broker or
nominee should  contact the broker or nominee to determine  whether and how they
may participate in the Plan.

     If the Fund declares a dividend payable either in Common Shares or in cash,
nonparticipants  will receive cash and participants in the Plan will receive the
equivalent  in Common  Shares.  If the market price of the Common  Shares on the
payment  date for the  dividend is equal to or exceeds  their net asset value as
determined on the payment date,  participants  will be issued Common Shares (out
of authorized  but unissued  shares) at a value equal to the higher of net asset
value or 95% of the market  price.  If the net asset  value  exceeds  the market
price of the Common Shares at such time, or if the Board of Trustees  declares a
dividend  payable  only in  cash,  the  Plan  Agent  will,  as  agent  for  Plan
participants,  buy shares in the open market,  on the New York Stock Exchange or
elsewhere,  for the participants' accounts. Such purchases will be made promptly
after the payable date for such  dividend  and, in any event,  prior to the next
ex-dividend  date, after such date except where necessary to comply with federal
securities  laws.  If, before the Plan Agent has completed  its  purchases,  the
market price exceeds the net asset value of the Common  Shares,  the average per
share  purchase  price paid by the Plan Agent may exceed the net asset  value of
the Common  Shares,  resulting  in the  acquisition  of fewer shares than if the
dividend had been paid in shares issued by the Fund.

     Participants  in the Plan may withdraw from the Plan upon written notice to
the Plan Agent.  Such withdrawal  will be effective  immediately if received not
less  than ten days  prior to a  dividend  record  date;  otherwise,  it will be
effective for all subsequent dividend record dates. When a participant withdraws
from the Plan or upon  termination of the Plan as provided  below,  certificates
for whole Common  Shares  credited to his or her account  under the Plan will be
issued and a cash payment  will be made for any fraction of a Share  credited to
such account.

     The  Plan  Agent  maintains  each  shareholder's  account  in the  Plan and
furnishes  monthly written  confirmations  of all  transactions in the accounts,
including  information  needed by the shareholders for personal and tax records.
Common Shares in the account of each Plan  participant  will be held by the Plan
Agent in  non-certificated  form in the name of the participant.  Proxy material
relating to the  shareholders'  meetings of the Fund will  include  those shares
purchased as well as shares held pursuant to the Plan.

     There will be no brokerage  charges with  respect to Common  Shares  issued
directly by the Fund.  However,  each  participant  will pay a pro rata share of
brokerage  commissions  incurred  with  respect to the Plan  Agent's open market
purchases in connection with the reinvestment of dividends and distributions. In
each case,  the cost per share of the shares  purchased  for each  participant's
account will be the average cost, including brokerage commissions, of any shares
purchased  on the open  market  plus the cost of any shares  issued by the Fund.
There are no other charges to participants for reinvesting  dividends or capital
gain  distributions,  except for certain  brokerage  commissions,  as  described
above.

     The automatic  reinvestment of dividends and distributions will not relieve
participants  of any  federal  income tax that may be payable or  required to be
withheld on such dividends or  distributions.  Participants  under the Plan will
receive tax information annually.  The amount of dividend to be reported on Form
1099-DIV should be (1) in the case of shares issued by the Fund, the fair market
value of such shares on the dividend payment date; and (2) in the case of shares
purchased by the
