Item 1.  Security and Issuer.
         -------------------

     This Amended  Schedule 13D  ("Amendment")  amends the Schedule 13D filed on
August 27, 2002.  This  Amendment  relates to shares of Common Stock,  par value
$0.001 (the "Shares") of PartsBase, Inc., a Delaware corporation ("Issuer"). The
address  of the  Issuer's  principal  executive  office  is 621 NW 53rd  Street,
Seventh Floor,  Boca Raton,  Florida 33487. The Reporting  Persons (as described
below) own an aggregate of 1,471,200 Shares as set forth in Item 5.

Item 2.  Identity and Background.
         -----------------------

     a. The  persons  filing  this  statement  are Atlas II,  LP  ("Atlas")  and
Marathon  Partners  LP  ("Marathon"),  collectively  referred to together as the
"Reporting Persons."

     b. The business  addresses for Atlas is 630 Fifth Avenue,  20th Floor,  New
York,  NY 10100 and for  Marathon is 52  Vanderbilt  Ave,  5th Fl, New York,  NY
10017.

     c. Atlas and Marathon manage and operate as investment funds.

     Neither of the Reporting Persons,  during the past five (5) years, have not
(i) been convicted in a criminal  proceeding  (excluding  traffic  violations or
similar misdemeanors),  or (ii) been a party to a civil proceeding of a judicial
or  administrative  body of  competent  jurisdiction,  and as a  result  of such
proceeding,  were or are subject to a judgment,  decree or final order enjoining
future violations of, or prohibiting or mandating  activities  subject to United
States federal or state securities laws or finding any violation with respect to
such laws.

Item 3.  Source and Amount of Funds or Other Consideration.
         -------------------------------------------------

     Not applicable.

Item 4.  Purpose of the Transactions.
         ---------------------------

     The Reporting  Persons are filing this  Amendment to state that they do not
intend to oppose the proposal by the Issuer's President,  Robert A. Hammond, Jr.
and Hammond I, Inc. to acquire all of the outstanding  Shares (other than shares
owned by Mr.  Hammond and  stockholders  owned or controlled by Mr.  Hammond) at
$1.50 per Share. In the Reporting  Persons' original Schedule 13D, they reported
their opposition to a proposal by Mr. Hammond to purchase all of the outstanding
Shares at $1.25 per Share.  The terms of the current proposal at $1.50 per Share
can be found in the  Issuer's  proxy  statement on Schedule  13E. The  Reporting
Persons  pursuant to the  attached  voting  agreement  agreed to give a proxy to
Hammond I, Inc. to vote 1,370,400  shares which they have shared voting power in
favor of the merger. The Reporting Persons will have no economic interest in the
acquiring  company,  but may be deemed part of the "group" formed by Mr. Hammond
and  Hammond I, Inc.  under Rule  13d-5(b)(1)  due to the voting  agreement.  As
permitted  under Rules  13d-1(k),  the  Reporting  Persons will continue to make
their own filing as they deem necessary to comply with Rule 13D.

     This filing does not constitute a  solicitation  for any proxy and is filed
to disclose  the intent of the  Reporting  Group.  Any  solicitation,  including
filing and sending a proxy statement, will be made directly by the Issuer.


Item 5.  Interest in Securities of the Issuer.
         ------------------------------------

     (a) The Reporting Persons  aggregately  beneficially own 1,471,200 or 10.5%
of the shares of Common Stock of the Issuer.

     (b)  Atlas  has  shared  voting  power  over  1,370,400   Shares  and  sole
dispositive  power over 866,000  shares.  Marathon has shared  voting power over
1,370,400  Shares and sole  dispositive  power over  605,200  (of which  100,800
Shares are held on behalf of clients'  managed accounts and 400 Shares are owned
by the children of Mario Cibelli, Managing Member of Marathon. Marathon does not
have  voting  power over the 100,800  Shares held on behalf of clients'  managed
accounts, but the clients generally follow his recommendations to them.).
