LINKING TRADITION
AND INNOVATION

At Vanguard, we treasure our rich nautical heritage--even as we steer our
course toward the twenty-first century. Our Report cover reflects that blending
of tradition and innovation, of past, present, and future.

The montage includes a bronze medallion with a likeness of our namesake, HMS
Vanguard (Lord Nelson's flagship at The Battle of the Nile); a clock built
circa 1816 in Scotland, featuring a portrait of Nelson; and several views of
our recently completed campus, which is steeped in nautical imagery--from our
buildings named after Nelson's warships (Victory, Majestic, and Goliath are
three shown), to our artwork and ornamental compass rose.

DEAR SHAREHOLDER,


     During the first half of Vanguard Florida Insured Tax-Free Fund's 1997
fiscal year, interest rates drifted unevenly upward as the surprising staying
power of the U.S. economy continued to stoke fears of higher inflation. While
the general rise in interest rates caused municipal bond prices to decline,
interest income was sufficient to give bonds a marginally positive total return
for the six months ended May 31, 1997. In this environment, our return
surpassed that of our average competitor, as shown in the table below.

     The Fund's total return (capital change plus reinvested dividends) is
based on a change in net asset value from $11.07 per share on November 30,
1996, to $10.94 per share on May 31, 1997, adjusted for dividends totaling
$0.281 per share from net investment income.

THE PERIOD IN REVIEW

The half-year was marked by swift reactions to each change in sentiment about
the strength of the U.S. economy and the possibility that inflation would
accelerate. In the taxable bond market, yields moved steadily higher during the
first four months of the period, only to retrace a few steps during the final
two months as concerns about inflation eased somewhat.

   Tax-Free Fund                  +1.4%
- --------------------------------------------
Average Florida Municipal Fund    +1.2
- --------------------------------------------
</TABLE>

     On balance, yields on longer-term U.S. Treasury securities ended the
period higher than they started. The yield on the benchmark 30-year U.S.
Treasury bond rose by 56 basis points (0.56 percentage point), from 6.35% on
November 30, 1996, to 6.91% on May 31, 1997. Municipal bonds withstood the
interest rate increase better than their taxable counterparts, thanks in part
to a reduced supply of new issues during the period. The yield on long-term
municipal bonds edged up on balance from 5.45% to 5.55%.

     The Fund's +1.4% total return during the half-year consisted of a +2.6%
income return and a capital decline of -1.2%, reflecting bond price declines
engendered by the modest increase in interest rates. This return bested that of
the average Florida municipal bond fund, but fell behind the +1.7% return of
the Lehman Municipal Bond Index. This national Index is a tough standard for
all state tax-free funds, existing, as it does, outside the "real world" of
operating expenses and transaction costs.

     Though recent history shows the harm that rising interest rates can
inflict on long-term bonds, the extended view reminds us that falling interest
rates periodically have the opposite effect. In the end, these changes amount
over time to little more than "noise," leaving the rate of interest income as
the main source of our long-term returns.

     Over these longer periods, our Fund is aided by our disciplined management
approach, as well as by our low expenses--durable advantages for our
shareholders that we expect to continue. Our Fund's expense ratio (expenses as
a percentage of average net assets) was 0.19% in fiscal 1996, compared with 1%
charged by the average Florida tax-free fund.


                                       1

     This cost advantage allows us to offer a portfolio of bonds that carry
private insurance guaranteeing the payment of principal and interest in the
event of an issuer's default--insurance that obviously comes at a cost--while
providing returns that are fully competitive with those of uninsured municipal
bond portfolios. Our expense ratio advantage aided our performance during the
brief semiannual period, just as it has done over longer periods (+8.6% for our
Fund versus +7.5% for our peers over the past twelve months, and an annualized
+7.5% return versus an annualized +6.4% for competing funds since the Fund's
September 1992 inception).

IN SUMMARY

It's worth noting that the mediocre performance of the U.S. bond market over
the past six months stands in stark contrast to that of the U.S. stock market,
which continued to steam ahead, gaining +13.1% (as measured by the Standard &
Poor's 500 Composite Stock Price Index).

     While it may be difficult for bond investors to watch the big gap between
the recent returns of stocks and bonds, it is exactly this lack of correlation
between the asset classes that makes the creation and maintenance of a balanced
investment program of stock funds, bond funds, and money market funds a prudent
move for mutual fund investors. As that gap narrows--or opens in favor of bonds
over stocks, as it will from time to time--the true value of a balanced program
will be evident.

     We look forward to reporting to you in further detail in our 1997 Annual
Report six months hence.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED MAY 31, 1997

U.S. EQUITY MARKETS

With the economy continuing to exhibit strong growth and modest levels of
inflation, investors in U.S. common stocks were rewarded with solid gains
during the past six months. The best performers were primarily
larger-capitalization issues, although the small-company indexes finally
exhibited some strength in May. For example, during the last six months, the
Standard & Poor's 500 Composite Stock Price Index gained 13.1%, fueled by a
6.1% boost in May. Reflecting the gains among smaller companies, the Russell
2000 Index posted an 8.4% increase for the six-month period, driven by an 11.1%
jump in May. It was particularly noteworthy that May's small-cap gains were led
by a 15.0% surge among small growth stocks, the worst segment of the U.S.
market during the past 12 months.

*Average annual.


     Stocks benefited from the continued strength of corporate earnings, which
rose some 15% during the past year. The strength in earnings and the
expectation that income will increase at an attractive pace helped stocks to
continue to produce solid gains in the fiscal period, despite the 0.6% increase
in the yield of the 10-year U.S. Treasury bond over the past six months. What's
more, earnings have shown not only good strength but remarkable consistency in
beating the consensus forecasts of Wall Street analysts.

     The strongest gains in the S&P 500 Index during the past six months came
from the technology sector (up 17.5%) and the consumer-staples sector (up
20.4%). By contrast, the more economically sensitive and less predictable
earnings of stocks in the materials & processing sector caused these issues to
lag the broad market, although, on an absolute basis, their 8.2% return over
six months is quite good.

U.S. FIXED-INCOME MARKETS

The general rise in interest rates during the past six months reflects the
economy's underlying momentum. The 10-year U.S. Treasury's yield increased from
6.04% at the end of November to 6.97% by the middle of April. Economic reports
released in the last several weeks of the period indicated a possible slowing
in economic growth, which reduced fears that inflation might accelerate and
helped interest rates fall to 6.66% by the end of May.




                                       3

     Fueled by robust consumer spending, the U.S. economy expanded at a strong
3.8% annual rate in the fourth quarter of 1996 and a remarkable 5.8% rate in
the first three months of 1997. The nation's unemployment rate, at 4.8% in May,
was the lowest in a generation. Strong economic growth and tight labor markets
often lead bond investors to expect an acceleration in inflation because of
increased demand for goods and services. Reflecting this expectation, the
Federal Reserve raised its federal funds interest rate target by 0.25% on March
25 in a "preemptive" strike against mounting inflationary pressures. Observed
price increases have been subdued in recent months, however. Wholesale prices
have fallen in each of the first four months of 1997, and so far this year
consumer prices have risen at a slower pace than last year.

     Higher interest rates dampened returns for bond investors. The Lehman
Brothers Aggregate Bond Index gained 0.94% over the past six months, reflecting
an income return of 3.43% that was partially offset by a capital decline of
- -2.49%. During this period, investors who favored shorter-maturity and
lower-quality issues achieved somewhat better returns. Mortgage-backed
securities continued to perform well because refinancing activity has been
reduced to historically low levels as interest rates have risen. Municipal
issues also tended to perform better than their taxable counterparts.

INTERNATIONAL EQUITY MARKETS

International investors fared reasonably well over the past six months. As
measured by the broad Morgan Stanley Capital International-Europe, Australasia,
Far East Index, foreign markets gained 4.2%.

     The period saw two major developments. First, the Japanese stock market
moved sharply higher in the spring, gaining 11% in May alone. Better tone in
the economy, plus strong earnings reported by export-oriented companies
benefiting from the weak yen, gave Japan a long-awaited boost. For the six
months, however, the Japanese market remained in negative territory (-5.5%).
The competitive benefits of a weak currency relative to the dollar extended to
Germany, where the export-driven capital goods and chemical manufacturers
gained; overall, the German market rose 12.4% during the six-month period.

     Arguably the biggest news came from the French elections at the end of
May. The new government is considered to be less friendly toward the austerity
measures needed to meet the eligibility requirements for the European Monetary
Union (EMU) in 1999. The French elections also had a broad impact across the
continent. Although most investors appear to agree that the elections won't
jeopardize the continent's move toward the EMU, the timing and intensity of the
fiscal measures are now less certain. Market reaction to the new French
government was mixed. France lost -2.1% in May (in francs), while Germany
gained 2.7% (in deutsche marks). For the six months, Europe gained 20.1% in
local currencies, which a strong dollar trimmed to 11.1% for U.S. investors.

REPORT FROM THE ADVISER


     Stronger-than-expected economic growth and concerns over inflation led to
a rise in interest rates during the six months ended May 31, 1997, the first
half of the fiscal year for Vanguard Florida Insured Tax-Free Fund. In March,
the Federal Reserve Board responded by increasing the federal funds rate a
quarter-point to 5.50%. Yields on the benchmark 30-year U.S. Treasury bond rose
0.56 percentage point to 6.91% during the six months, while yields on
long-term, high-quality municipal bonds increased a mere 0.10 percentage point
to 5.55%.

     The magnitude of the rise in rates was partially mitigated by strong
investor demand and reduced supply in the municipal market. Consequently,
yields of long-term, high-grade tax-exempt bonds rose less in relation to
yields on U.S. Treasury bonds, from a ratio of 86% last November 30 to 80% on
May 31. While the lack of supply helped the performance of municipal bonds
relative to Treasuries, it also resulted in a compression of the yield
differentials between higher- and lower-quality municipal securities. Over the
short term, such an environment is often advantageous to the price performance
of mutual funds holding lower-quality bonds. In contrast, Vanguard's state
tax-free Portfolios are insured and adhere to significantly higher quality
standards than the typical mutual fund. Nonetheless, the Portfolios provided
returns competitive with those of lower-quality competitors.

     During the first fiscal half, we pursued two strategies to maximize
tax-exempt income and minimize risk. First, we lowered the effective maturities
of the Portfolios, which reduced their exposure to rising interest rates and
preserved principal. This was accomplished by offsetting our market exposure
through hedges in (i.e., sales of) Treasury futures contracts, while
maintaining our holdings of municipal bonds. Second, we overweighted our
holdings of intermediate-term bonds with maturities of 10-20 years.
Intermediate bonds currently offer the best relative value because they
generate 95% of the yield of long-term municipal bonds while providing less
price volatility. In combination, these strategies enabled us to reduce our
exposure to interest rate changes, maintain a high tax-exempt dividend stream,
and capitalize on the relative outperformance of municipal bonds.

     Vanguard's investment objective is to provide consistent above-average
performance relative to our competitors. We accomplish this by combining a
disciplined management approach with a low expense ratio. Over the long term,
we believe this philosophy will continue to produce superior performance and a
durable tax-exempt dividend for our shareholders.

     The second half of the fiscal year will require investors to remain
vigilant because of the possibility of further increases in the federal funds
rate by the Federal Reserve Board.

INVESTMENT PHILOSOPHY

The Fund reflects a belief that a high level of current income exempt from
federal income tax and Florida's intangible personal property tax can be
achieved by investing primarily in long-term insured bonds issued by state,
county, and municipal governments in Florida.

FINANCIAL STATEMENTS
MAY 31, 1997 (unaudited)

STATEMENT OF NET ASSETS

This Statement provides a detailed list of the Fund's municipal bond holdings,
including each security's market value on the last day of the reporting period
and information on credit enhancements (insurance or letters of credit).
Securities are grouped and subtotaled according to their insured or noninsured
status. Other assets are added to, and liabilities are subtracted from, the
value of Total Municipal Bonds to calculate the Fund's Net Assets. Finally, Net
Assets are divided by the outstanding shares of the Fund to arrive at its share
price, or Net Asset Value (NAV) Per Share.

     At the end of the Statement of Net Assets, you will find a table
displaying the composition of the Fund's net assets on both a dollar and
per-share basis. Undistributed Net Investment Income is usually zero because
the Fund distributes its net income to shareholders as a dividend each day. Any
realized gains must be distributed annually, so the bulk of net assets consists
of Paid in Capital (money invested by shareholders). The balance shown for
Accumulated Net Realized Gains usually approximates the amount available to
distribute to shareholders as taxable capital gains as of the statement date,
but may differ because certain investments or transactions may be treated
differently for financial statement and tax purposes. Any Accumulated Net
Realized Losses, and any cumulative excess of distributions over net realized
gains, will appear as negative balances. Unrealized Appreciation (Depreciation)
is the difference between the value of the Fund's investments and their cost,
and reflects the gains (losses) that would be realized if the Fund were to sell
all of its investments at their statement-date values.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how the Fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
that is detailed in the Statement of Operations. Because the Fund distributes
its income to shareholders each day, the amounts of Distributions--Net
Investment Income generally equal the net income earned as shown under the
Operations section. The amounts of Distributions--Realized Capital Gain may not
match the capital gains shown in the Operations section, because distributions
are determined on a tax basis and may be made in a period different from the
one in which the gains were realized on the financial statements. The Capital
Share Transactions section shows the amount shareholders invested in the Fund,
either by purchasing shares or by reinvesting distributions, and the amounts
redeemed. The corresponding numbers of Shares Issued and Redeemed are shown at
the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes the Fund's investment results and distributions to
shareholders on a per-share basis. It also presents the Fund's Total Return and
shows net investment income and expenses as percentages of average net assets.
These data will help you assess: the variability of the Fund's net income and
total returns from year to year; the relative contributions of net income and
capital gains to the Fund's total return; how much it costs to operate the
Fund; and the extent to which the Fund tends to distribute capital gains. The
table also shows the Portfolio Turnover Rate, a measure of trading activity. A
turnover rate of 100% means that the average security is held in the Fund for
one year.

NOTES TO FINANCIAL STATEMENTS

Vanguard Florida Insured Tax-Free Fund is registered under the Investment
Company Act of 1940 as an open-end investment company, or mutual fund. The Fund
invests in debt instruments of municipal issuers whose ability to meet their
obligations may be affected by economic and political developments in the state
of Florida.

A. The following significant accounting policies conform to generally accepted
accounting principles for mutual funds. The Fund consistently follows such
policies in preparing its financial statements.

     1. SECURITY VALUATION: Bonds, and temporary cash investments acquired more
than 60 days to maturity, are valued using the latest bid prices or using
valuations based on a matrix system (which considers such factors as security
prices, yields, maturities, and credit ratings), both as furnished by
independent pricing services. Other temporary cash investments are valued at
amortized cost, which approximates market value.

     2. FEDERAL INCOME TAXES: The Fund intends to continue to qualify as a
regulated investment company and distribute all of its income. Accordingly, no
provision for federal income taxes is required in the financial statements.

     3. FUTURES CONTRACTS: The Fund may use Municipal Bond Index, U.S. Treasury
Bond, and U.S. Treasury Note futures contracts, with the objectives of
enhancing returns, managing interest rate risk, maintaining liquidity,
diversifying credit risk, and minimizing transaction costs. The Fund may
purchase or sell futures contracts instead of bonds to take advantage of
pricing differentials between the futures contracts and the underlying bonds.
The Fund may also seek to take advantage of price differences among bond market
sectors by simultaneously buying futures (or bonds) of one market sector and
selling futures (or bonds) of another sector. Futures contracts may also be
used to simulate a fully invested position in the underlying bonds while
maintaining a cash balance for liquidity. The primary risks associated with the
use of futures contracts are imperfect correlation between changes in market
values of bonds held by the Fund and the prices of futures contracts, and the
possibility of an illiquid market.

     Futures contracts are valued based upon their quoted daily settlement
prices. The aggregate principal amounts of the contracts are not recorded in
the financial statements. Fluctuations in the value of the contracts are
recorded in the Statement of Net Assets as an asset (liability) and in the
Statement of Operations as unrealized appreciation (depreciation) until the
contracts are closed, when they are recorded as realized futures gains
(losses).

     4. DISTRIBUTIONS: Distributions from net investment income are declared
daily and paid on the first business day of the following month. Annual
distributions from realized capital gains, if any, are recorded on the
ex-dividend date.

     5. OTHER: Security transactions are accounted for on the date securities
are bought or sold. Costs used to determine realized gains (losses) on the sale
of investment securities are those of the specific securities sold. Premiums
and original issue discounts are amortized and accreted, respectively, to
interest income over the lives of the respective securities.

B. The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to the Fund under methods approved by the board of
trustees. At May 31, 1997, the Fund had contributed capital of $44,000 to
Vanguard (included in Other Assets), representing 0.2% of Vanguard's
capitalization. The Fund's trustees and officers are also directors and
officers of Vanguard.

C. The Fund's custodian bank has agreed to reduce its fees when the Fund
maintains cash on deposit in the non-interest-bearing custody account. For the
six months ended May 31, 1997, custodian fee offset arrangements reduced
expenses by $7,000.


                                      14

<PAGE>   17



D. During the six months ended May 31, 1997, the Fund purchased $113,717,000 of
investment securities and sold $62,530,000 of investment securities, other than
temporary cash investments.

E. Capital gains (losses) may be realized in a different time period for tax
purposes than for financial reporting purposes. At November 30, 1996, the Fund
had available a capital loss carryforward of $304,000 to offset future net
capital gains through November 30, 2003.

F. At May 31, 1997, net unrealized appreciation of investment securities for
financial reporting and federal income tax purposes was $19,242,000, consisting
of unrealized gains of $19,589,000 on securities that had risen in value since
their purchase and $347,000 in unrealized losses on securities that had fallen
in value since their purchase.

     At May 31, 1997, the aggregate settlement value of open futures contracts
expiring in June 1997 and the related unrealized depreciation were:
