                               THE HENLOPEN FUND

                               SEMIANNUAL REPORT
                               DECEMBER 31, 2004

To My Fellow Shareholders:

For the quarter ended December 31, 2004, The Henlopen Fund increased 12.39%.
Annualized returns for the Fund for 1, 5 and 10 years are 16.78%, 4.58%, and
17.14%, respectively.  Since our inception on December 2, 1992, the Fund has an
annualized return of 16.23%.

The December quarter saw a broad-based rally that lifted the major indices into
positive territory for the year.  Whether it was relief over a clean conclusion
to a divisive presidential election or normal seasonal bias, investor sentiment
turned decidedly positive during the quarter.  The breadth of the rally was
evidenced throughout The Henlopen Fund portfolio with especially strong gains
found among the Fund's holdings in the gaming, tanker, homebuilding and
financial sectors.  The Fund continues to be positioned to benefit from our
belief that energy prices are in the midst of a secular upturn but that the
economy, being less impacted by higher energy costs than in past decades, will
show continued growth.

A rise in speculative behavior in the quarter and a disturbingly weak "Santa
Claus rally" at year-end raises a near-term caution flag, as does the knowledge
that both the bull market and the economic recovery are both one year older.
However, the bigger picture is that we exit the year with much the same
backdrop as we entered it:  Interest rates are low and expected to rise at a
"measured" pace; inflation is occasionally spoken about but rarely seen; and
the economy continues to grow at a respectable and non-threatening rate.  This
environment has proven favorable for our stock-picking style in the past, and
we will continue to work hard to benefit our current shareholders.

On December 29, 2004, our Board of Trustees declared an income dividend of
$0.01002 per share, payable December 30, 2004, to shareholders of record on
December 28, 2004.

Sincerely yours,

Performance data quoted represents past performance; past performance does not
guarantee future results.  The investment return and principal value of an
investment will fluctuate so that an investor's shares, when redeemed, may be
worth more or less than their original cost.  Current performance of the Fund
may be lower or higher than the performance quoted.  Performance data current
to the most recent month end may be obtained by visiting www.henlopenfund.com.
The graph does not reflect the deduction of taxes that a shareholder would pay
on Fund distributions or the redemption of Fund shares.

                                COST DISCUSSION

As a shareholder of the Fund you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments, reinvested
dividends, or other distributions; redemption fees; and exchange fees; and (2)
ongoing costs, including management fees and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in The Henlopen Fund and to compare these costs with the ongoing costs of
investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period from June 30, 2004 through December 31,
2004.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period.  Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

In addition to the costs highlighted and described below, the only Fund
transaction costs you might currently incur would be wire fees ($15 per wire),
if you choose to have proceeds from a redemption wired to your bank account
instead of receiving a check.  Additionally, U.S. Bank charges an annual
processing fee ($15) if you maintain an IRA account with the Fund. To determine
your total costs of investing in the Fund, you would need to add any applicable
wire or IRA processing fees you've incurred during the period to the costs
provided in the example at the end of this article.


HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds.  To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads), redemption or exchange fees.  Therefore, the second line of the
table is useful in comparing ongoing costs only, and will not help you determine
the relative total costs of owning different funds.  In addition, if these
transactional costs were included, your costs would have been higher.

                         NOTES TO FINANCIAL STATEMENTS
                         December 31, 2004 (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 Office
     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. The fair value of a security
     is the amount which the Fund might reasonably expect to receive upon a
     current sale. The fair value of a security may differ from the last
     quoted price and the Fund may not be able to sell a security at the
     fair value. Market quotations may not be available, for example, if
     trading in particular securities was halted during the day and not
     resumed prior to the close of trading on the New York Stock Exchange.
     Short-term investments with maturities of 60 days or less are valued at
     amortized 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 1.0% 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.

     In the normal course of business the Fund enters into contracts with
     service providers that contain general indemnification clauses. The Fund's
     maximum exposure under these arrangements is unknown as this would involve
     future claims that may be made against the Fund that have not yet occurred.
     However, based on experience, the Fund expects the risk of loss to be
     remote.

(3)  DISTRIBUTIONS TO SHAREHOLDERS --

     Net investment income and net realized gains, if any, are distributed to
     shareholders at least annually. On December 29, 2004, the Fund distributed
     $108,497 from net investment income ($0.01002 per share). The distribution
     was paid on December 30, 2004, to shareholders of record on December 28,
     2004.

(4)  INVESTMENT TRANSACTIONS --

     For the period ending December 31, 2004, purchases and proceeds of sales of
     investment securities (excluding short-term securities) were $313,134,169
     and $350,879,250, respectively.

(5)  ACCOUNTS PAYABLE AND ACCRUED LIABILITIES --

     As of December 31, 2004, liabilities of the Fund included the following:

          Payable to shareholders for redemptions                $4,556,032
          Payable to brokers for investments purchased            2,559,994

          Other liabilities                                          45,305

(6)  SOURCES OF NET ASSETS --

     As of December 31, 2004 the sources of net assets were as follows:

          Fund shares issued and outstanding                   $299,268,289
          Net unrealized appreciation on investments             35,129,649
          Accumulated net realized loss                          (7,329,909)
          Accumulated net investment loss                        (1,189,371)

                                                               $325,878,658
                                                               ------------
                                                               ------------

  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 and for mark to
  market for Passive Foreign Investment Companies ("PFICs").The tax components
  of dividends paid during the years ended June 30, 2004 and 2003, capital loss
  carryovers, which may be used to offset future capital gains, subject to
  Internal Revenue Code limitations, (expiring in 2011), as of June 30, 2004,
  and tax basis post-October losses as of June 30, 2004, which are not
  recognized for tax purposes until the first day of the following fiscal year
  are:

  

                                 JUNE 30, 2004                                                    JUNE 30, 2003

       $  --                  $  --             $8,943,326             $  --                $  --               $  --

  

  The Fund has utilized $14,631,388 of its post-October losses from the prior
  year to decrease current year net capital gains.

  The Fund has also utilized $11,975,664 of its capital loss carryovers during
  the year ended June 30, 2004.

  Since there were no ordinary distributions paid for the year ended June 30,
  2004, there were no distributions designated as qualifying for the dividends
  received deduction for corporate shareholders nor as qualified dividend
  income under the Jobs and Growth Tax Relief Act of 2003.

(8)  OTHER --

     On June 22, 2004 the Securities and Exchange Commission filed a civil
     action in the United States District Court for the Eastern District of
     Pennsylvania against, among others, the Fund's investment adviser, Landis
     Associates LLC, and its principal, Michael L. Hershey, the President of the
     Fund and a member of the Fund's Board of Trustees.  The complaint in the
     civil action alleges that Mr. Hershey and Landis Associates LLC violated
     certain federal securities laws by breaching their fiduciary duty to a
     wealthy private client in connection with investments made by the client in
     a private company between 1998 and 2001.  The complaint seeks an injunction
     against Mr. Hershey and Landis Associates LLC for violating the federal
     securities laws it alleges were violated in connection with such private
     client's investments.

     The allegations raised in the complaint do not involve the Fund nor the
     type of investments which the Fund makes.  If the court issues the
     injunction requested by the Securities and Exchange Commission, Landis
     Associates LLC would no longer be eligible to serve as the Fund's
     investment adviser and Mr. Hershey would no longer be eligible to serve as
     an officer or trustee of the Fund.  Landis Associates LLC and Mr. Hershey
     have advised the Fund that they deny all allegations of wrongdoing, intend
     to vigorously contest the allegations raised by the Securities and Exchange
     Commission and believe they will be successful in their defense.
