                               THE HENLOPEN FUND

                               SEMIANNUAL REPORT
                               DECEMBER 31, 2003

To My Fellow Shareholders:

For the quarter ended December 31, 2003, The Henlopen Fund increased 16.41%.
Annualized returns for the Fund for 1, 3, 5 and 10 years are 64.98%, 9.57%,
11.68%, and 15.02%, respectively.  Since our inception on December 2, 1992, the
Fund has an annualized return of 16.18%.

The December quarter capped off a year of strong gains for all the major
indices.  The acceleration of economic growth and overall improvement in
employment statistics mentioned in our September quarterly letter continued to
drive investor enthusiasm, as evidenced by strong performance across most
industry sectors.  The Henlopen Fund again benefited from broad-based gains,
with holdings in technology, financial services and energy making the strongest
advances.  The Fund increased its exposure to the biotechnology sector during
the year, as we believe the industry will yield many of the next generation of
therapeutic advances.  Our thesis appears to have been validated during the
December quarter as two of these holdings, Applied Molecular Evolution and
Esperion Therapeutics, were acquired by large pharmaceutical companies looking
to strengthen their drug pipelines.

The climate for equities remains favorable, as the economy continues to
strengthen and interest rates remain extremely low.  Valuation levels of stock
indices and the threat of future interest rate hikes should provide fodder for
the bears and increase market volatility in the year ahead, but companies with
strong growth prospects and solid management execution should continue to be
rewarded with higher stock prices.  We will continue our efforts to position the
Fund in such companies for our shareholders' benefit.

Sincerely yours,

/s/Michael L. Hershey                           /s/Bruce V. Vogenitz

                         NOTES TO FINANCIAL STATEMENTS
                         December 31, 2003 (Unaudited)

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES --

     The following is a summary of significant accounting policies of The
     Henlopen Fund (the "Fund"), which is organized as a Delaware Business Trust
     and is registered as a diversified open-end management company under the
     Investment Company Act of 1940, as amended. The Fund commenced operations
     on December 2, 1992. The investment objective of the Fund is long-term
     capital appreciation.

     (a)  Each security, excluding short-term investments, is valued at the
     last sale price reported by the principal security exchange on which
     the issue is traded, securities that are traded on the Nasdaq National
     Market or the Nasdaq Smallcap Market are valued at the Nasdaq Official
     Closing Price, or if no sale is reported, the latest bid price.
     Securities which are traded over-the-counter are valued at the latest
     bid price. Securities for which quotations are not readily available
     are valued at fair value as determined by the investment adviser under
     the supervision of the Board of Trustees. Short-term investments with
     maturities of 60 days or less are valued at cost which approximates
     market value. For financial reporting purposes, investment transactions
     are recorded on trade date.

     (b)  Net realized gains and losses on sales of securities are computed
     on the identified cost basis.

     (c)  Dividend income is recorded on the ex-dividend date. Interest
     income is recorded on the accrual basis.

     (d)  The Fund has investments in short-term variable rate demand notes,
     which are unsecured instruments. The Fund may be susceptible to credit
     risk with respect to these notes to the extent the issuer defaults on
     its payment obligation. The Fund's policy is to monitor the
     creditworthiness of the issuer and nonperformance by these
     counterparties is not anticipated.

     (e)  Accounting principles generally accepted in the United States of
     America ("GAAP") require that permanent differences between income for
     financial reporting and tax purposes be reclassified in the capital
     accounts.

     (f)  The preparation of financial statements in conformity with GAAP
     requires management to make estimates and assumptions that affect the
     reported amounts of assets and liabilities and disclosure of contingent
     assets and liabilities at the date of the financial statements and the
     reported amounts of revenues and expenses during the reporting period.
     Actual results could differ from these estimates.

     (g)  Provision has not been made for Federal income taxes since the
     Fund has elected to be taxed as a "regulated investment company" and
     intends to distribute substantially all net investment company taxable
     income and net capital gains to its shareholders and otherwise comply
     with the provisions of the Internal Revenue Code applicable to
     regulated investment companies.

     (h)  The Fund imposes a 1% redemption fee on the value of shares
     redeemed less than 30 days after purchase.  The redemption fee will not
     apply to shares purchased through reinvested distributions (dividends
     and capital gains), shares held in retirement plans or through the
     systematic withdrawal plan.  The redemption fee is designed to
     discourage short-term trading and any proceeds of the fee will be
     credited to paid in capital.

(2)  INVESTMENT ADVISER AND MANAGEMENT AGREEMENT AND TRANSACTIONS WITH RELATED
     PARTIES --

     The Fund has a management agreement with Landis Associates LLC (the
     "Adviser"), with whom certain officers and trustees of the Fund are
     affiliated, to serve as investment adviser and manager. Under the terms of
     the agreement, the Fund will pay the Adviser a monthly management fee at
     the annual rate of 1% on the daily net assets of the Fund.

     The Fund has an administrative agreement with Fiduciary Management, Inc.
     ("FMI"), with whom an officer of the Fund is affiliated, to supervise all
     aspects of the Fund's operations except those performed by the Adviser.
     Under the terms of the agreement, the Fund will pay FMI a monthly
     administrative fee at the annual rate of 0.2% on the first $30,000,000 of
     the daily net assets of the Fund, 0.1% on the daily net assets of the Fund
     on the next $30,000,000 and 0.05% on the daily net assets of the Fund over
     $60,000,000.

                                                                  ------------
                                                                  ------------

     The difference, if any, between the cost amount for financial statement and
     federal income tax purposes is due primarily to timing differences in
     recognizing certain gains and losses in security transactions.

     The tax components of dividends paid during the year ended June 30, 2003,
     capital loss carryovers (expiring in 2011), as of June 30, 2003, and tax
     basis post-October losses as of June 30, 2003, which are not recognized for
     tax purposes until the first day of the following fiscal year are:

           ORDINARY        LONG -TERM       NET CAPITAL
            INCOME        CAPITAL GAINS         LOSS          POST-OCTOBER
        DISTRIBUTIONS     DISTRIBUTIONS      CARRYOVERS          LOSSES
        -------------     -------------     -----------       ------------
            $  --             $  --         $20,918,990        $14,631,388

     Since there were no ordinary distributions paid for the year ended June 30,
     2003, there were no distributions designated as qualifying for the
     dividends received deduction for corporate shareholders.
