ITEM 1. REPORTS TO STOCKHOLDERS.

                           THE GABELLI UTILITIES FUND

                               SEMI-ANNUAL REPORT
                                  JUNE 30, 2003


TO OUR SHAREHOLDERS,

      We are  changing  the way we provide  portfolio  managers'  commentary  to
shareholders  of our Funds.  Our  shareholder  reports have typically  contained
commentary  on  each  portfolio  manager's   assessment  of  the  stock  market,
individual  stocks and how economic  events affect their  thinking in managing a
specific Fund. We have always provided  details about  performance and presented
returns,  both good and bad,  hopefully  in a clear and concise  fashion.  These
comments have been included as part of each Fund's quarterly,  semi-annual,  and
annual financial statements.

      The Sarbanes-Oxley Act's new corporate governance  regulations now require
a Fund's  principal  executive  and  financial  officers  to certify  the entire
contents of  shareholder  reports in a filing with the  Securities  and Exchange
Commission on form N-CSR.  This  certification  covers the  portfolio  manager's
commentary  and  subjective  opinions  if they are  attached to or a part of the
financial statements.

      Rather than ask our portfolio  managers to eliminate their opinions and/or
restrict  their  commentary  to  historical  facts only,  we are removing  their
commentary from the financial statements and sending it to you separately.  As a
result,  this commentary will no longer be considered part of a Fund's financial
report and therefore will not be subject to the officers' certifications.

      We  trust  that  you  understand   that  our  approach  is  an  unintended
consequence of the  ever-increasing  regulatory  requirements  affecting  public
companies generally.  We hope the specific  certification  requirements of these
new  regulations  will be  modified  as  they  relate  to  mutual  funds,  since
investment  companies have different  corporate  structures and objectives  than
other public companies.

                                                     Sincerely yours,




                                                     /S/ BRUCE N. ALPERT

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

1.  ORGANIZATION.  The Gabelli  Utilities Fund (the "Fund") was organized on May
18,  1999 as a Delaware  Business  Trust.  The Fund is a  diversified,  open-end
management  investment  company  registered under the Investment  Company Act of
1940, as amended (the "1940 Act").  The Fund commenced  operations on August 31,
1999.  The Fund's  primary  objective is to provide a high level of total return
through a combination of capital appreciation and current income.

2. SIGNIFICANT  ACCOUNTING POLICIES.  The preparation of financial statements in
accordance with accounting  principles  generally  accepted in the United States
requires  management to make estimates and assumptions  that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those  estimates.  The  following  is a summary of  significant  accounting
policies followed by the Fund in the preparation of its financial statements.

SECURITY  VALUATION.  Portfolio  securities  listed or  traded  on a  nationally
recognized securities exchange or traded in the U.S. over-the-counter market for
which market quotations are readily available are valued at the last quoted sale
price or a market's  official  closing  price as of the close of business on the
day the  securities  are being  valued.  If there  were no sales  that day,  the
security is valued at the  average of the  closing  bid and asked  prices or, if
there were no asked  prices  quoted on that day,  then the security is valued at
the closing bid price on that day. If no bid or asked  prices are quoted on such
day,  the  security is valued at the most  recently  available  price or, if the
Board of Trustees

                                       4

THE GABELLI UTILITIES FUND
NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)
- --------------------------------------------------------------------------------

so determines,  by such other method as the Board of Trustees shall determine in
good faith,  to reflect its fair market value.  Portfolio  securities  traded on
more than one national securities exchange or market are valued according to the
broadest and most  representative  market,  as determined by Gabelli Funds,  LLC
(the "Adviser").  Portfolio  securities  primarily traded on foreign markets are
generally  valued at the preceding  closing  values of such  securities on their
respective exchanges.  Securities and assets for which market quotations are not
readily  available  are valued at their fair value as  determined  in good faith
under procedures  established by and under the general  supervision of the Board
of Trustees.  Short term debt securities with remaining maturities of 60 days or
less are valued at amortized cost, unless the Board of Trustees  determines such
does not reflect the securities fair value, in which case these  securities will
be valued at their  fair  value as  determined  by the Board of  Trustees.  Debt
instruments  having a maturity greater than 60 days for which market  quotations
are  readily  available  are valued at the  latest  average of the bid and asked
prices. If there were no asked prices quoted on such day, the security is valued
using the  closing  bid price.  Options are valued at the last sale price on the
exchange on which they are listed.  If no sales of such options have taken place
that day,  they will be valued at the mean between  their  closing bid and asked
prices.

REPURCHASE  AGREEMENTS.  The Fund may  enter  into  repurchase  agreements  with
primary  government  securities dealers recognized by the Federal Reserve Board,
with member banks of the Federal Reserve System or with other brokers or dealers
that meet credit guidelines established by the Adviser and reviewed by the Board
of Trustees.  Under the terms of a typical repurchase agreement,  the Fund takes
possession  of an  underlying  debt  obligation  subject to an obligation of the
seller to repurchase,  and the Fund to resell,  the obligation at an agreed-upon
price and time, thereby  determining the yield during the Fund's holding period.
The Fund will always receive and maintain  securities as collateral whose market
value, including accrued interest,  will be at least equal to 102% of the dollar
amount  invested by the Fund in each  agreement.  The Fund will make payment for
such  securities  only upon  physical  delivery  or upon  evidence of book entry
transfer of the collateral to the account of the  custodian.  To the extent that
any repurchase transaction exceeds one business day, the value of the collateral
is marked-to-market on a daily basis to maintain the adequacy of the collateral.
If the seller defaults and the value of the collateral declines or if bankruptcy
proceedings   are  commenced  with  respect  to  the  seller  of  the  security,
realization of the collateral by the Fund may be delayed or limited.

SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME.  Securities  transactions  are
accounted  for on the  trade  date  with  realized  gain or loss on  investments
determined  by using the  identified  cost method.  Interest  income  (including
amortization  of premium  and  accretion  of  discount)  is  recorded as earned.
Dividend income is recorded on the ex-dividend date.

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS.  Dividends and  distributions to
shareholders  are recorded on the ex-dividend  date.  Income  distributions  and
capital gain  distributions are determined in accordance with Federal income tax
regulations which may differ from accounting  principles  generally  accepted in
the United States.  These differences are primarily due to differing  treatments
of income and gains on various  investment  securities held by the Fund,  timing
differences and differing  characterization  of distributions  made by the Fund.

PROVISION  FOR  INCOME  TAXES.  The Fund  intends  to  continue  to qualify as a
regulated  investment company under Subchapter M of the Internal Revenue Code of
1986, as amended. As a result, a Federal income tax provision is not required.

The Fund has a net capital loss  carryforward for Federal income tax purposes at
December 31, 2002 of $1,798,633.  This capital loss carryforward is available to
reduce future distributions of net capital gains to shareholders.  $1,088,544 of
the loss carryforward is available  through 2008;  $655,271 is available through
2009; and $54,818 is available through 2010.

3.  INVESTMENT  ADVISORY  AGREEMENT.  The Fund has  entered  into an  investment
advisory  agreement (the "Advisory  Agreement")  with the Adviser which provides
that the Fund will pay the Adviser a fee,  computed  daily and paid

                                       5

monthly,  at the annual rate of 1.00% of the value of the Fund's  average  daily
net assets.  In accordance with the Advisory  Agreement,  the Adviser provides a
continuous   investment   program  for  the  Fund's   portfolio,   oversees  the
administration  of all aspects of the Fund's  business  and affairs and pays the
compensation  of all Officers  and Trustees of the Fund who are its  affiliates.
The Adviser contractually agreed to reimburse expenses of the Fund to the extent
necessary to maintain the annualized total operating  expenses for Class AAA, A,
B, and C of 2.00%, 2.00%,  2.75% and 2.75%,  respectively,  of average daily net
assets.  For the six months ended June 30, 2003, the Adviser reimbursed the Fund
in the amount of $1,775.  The Fund is obliged to repay the  Adviser for a period
of two fiscal years  following  the fiscal year in which the Adviser  reimbursed
the Fund only to the extent that the  operating  expenses of the Fund fall below
2.00%,  2.00%, 2.75% and 2.75% of average  daily net assets for Class AAA, A, B,
andC,  respectively.  The cumulative amount which the Fund may repay the Adviser
is $122,750.

4.  DISTRIBUTION  PLAN.  The Fund's Board of Trustees has adopted a distribution
plan (the "Plan") for each class of shares pursuant to Rule 12b-1 under the 1940
Act.  For the six months  ended June 30, 2003,  the Fund  incurred  distribution

(a)      The registrant's  principal executive and principal financial officers,
         or  persons  performing  similar  functions,  have  concluded  that the
         registrant's  disclosure  controls and  procedures  (as defined in Rule
         30a-3(c)  under the  Investment  Company Act of 1940,  as amended  (the
         "1940 Act") (17 CFR 270.30a-3(c)))  are effective,  as of a date within
         90 days of the filing date of the report that  includes the  disclosure
         required by this paragraph, based on their evaluation of these controls
         and  procedures  required by Rule  30a-3(b)  under the 1940 Act (17 CFR
         270.30a-3(b))  and Rules  13a-15(b) or 15d-15(b) under the Exchange Act
         (17 CFR 240.13a-15(b) or 240.15d-15(b)).


(b)      There  were  no  changes  in the  registrant's  internal  control  over
         financial reporting (as defined in Rule 30a-3(d) under the 1940 Act (17
         CFR  270.30a-3(d))  that occurred during the  registrant's  last fiscal
         half-year (the  registrant's  second fiscal half-year in the case of an
         annual report) that has materially affected, or is reasonably likely to
         materially  affect,  the  registrant's  internal control over financial
         reporting.
