                                  RISK FACTORS

     Any investment in our stock involves a high degree of risk. We have
identified a number of risk factors which you should consider before buying
shares of our common stock. These risk factors are incorporated by reference
into this registration statement from our annual report on Form 20-F filed on
June 30, 2006. Some of these risk factors contained in our annual report on Form
20-F relate principally to the industry in which we operate and our business in
general. Other risks relate to the securities market for and ownership of our
common stock. Any of these risk factors could significantly and negatively
affect our business, financial condition, operating results and common stock
price.

                           FORWARD-LOOKING STATEMENTS

     This prospectus, and the documents incorporated by reference in this
prospectus, contain forward-looking statements. These forward-looking statements
include information about possible or assumed future results of our operations
or our performance. Words such as "expects," "intends," "plans," "believes,"
"anticipates," "estimates," and variations of such words and similar expressions
are intended to identify the forward-looking statements. Although we believe
that the expectations reflected in such forward-looking statements are
reasonable, no assurance can be given that such expectations will prove to have
been correct. These statements involve known and unknown risks and are based
upon a number of assumptions and estimates which are inherently subject to
significant uncertainties and contingencies, many of which are beyond our
control. Actual results may differ materially from those expressed or implied by
such forward-looking statements. Forward-looking statements include statements
regarding:

     o    our future operating or financial results;

     o    future, pending or recent acquisitions, business strategy, areas of
          possible expansion, and expected capital spending or operating
          expenses; and

     o    drybulk and containership market trends, including charter rates and
          factors affecting vessel supply and demand.

     We undertake no obligation to publicly update or revise any forward-looking
statements contained in this prospectus, or the documents to which we refer you
in this prospectus, to reflect any change in our expectations with respect to
such statements or any change in events, conditions or circumstances on which
any statement is based.

                                 USE OF PROCEEDS

     We will not receive any proceeds from sales of shares of our common stock
by the selling shareholders.

                              PLAN OF DISTRIBUTION

     We are registering shares of our common stock under the Securities Act for
sale by the selling shareholders. As used in this prospectus, "selling
shareholders" include certain entities identified in the footnotes to the table
in the section captioned "Selling Shareholders" as the holders of record of the
indicated securities and include the respective pledgees, assignees,
successors-in-interest, donees, transferees or others who may later hold the
selling shareholders' Euroseas common stock and would be identified in an
amendment to this prospectus at the appropriate time. We have agreed to pay the
costs and fees of registering the shares, but the selling shareholders will pay
any brokerage commissions, discounts or other expenses relating to the sale of
the shares.

      The selling shareholders will sell their shares at prevailing market
prices or privately negotiated prices. A Selling Shareholder may use any one or
more of the following methods when selling shares:

     o    ordinary brokerage transactions and transactions in which the
          broker-dealer solicits purchasers;

     o    block trades in which the broker-dealer will attempt to sell the
          shares as agent but may position and resell a portion of the block as
          principal to facilitate the transaction;

     o    purchases by a broker-dealer as principal and resale by the
          broker-dealer for its account;

     o    an exchange distribution in accordance with the rules of the
          applicable exchange;

     o    privately negotiated transactions;

     o    settlement of short sales entered into after the effective date of the
          registration statement of which this prospectus is a part;

     o    broker-dealers may agree with the Selling Stockholders to sell a
          specified number of such shares at a stipulated price per share;

     o    a combination of any such methods of sale;

     o    through the writing or settlement of options or other hedging
          transactions, whether through an options exchange or otherwise; or

     o    any other method permitted pursuant to applicable law.

     The Selling Shareholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

     Broker-dealers engaged by the Selling Shareholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Shareholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated, but, except as set forth in a supplement to this prospectus, in the
case of an agency transaction not in excess of a customary brokerage commission
in compliance with NASDR Rule 2440; and in the case of a principal transaction a
markup or markdown in compliance with NASDR IM-2440.

     In connection with the sale of Euroseas common stock or interests therein,
the Selling Shareholders may enter into hedging transactions with broker-dealers
or other financial institutions, which may in turn engage in short sales of the
common stock in the course of hedging the positions they assume. The Selling
Shareholders may also sell shares of the common stock short and deliver these
securities to close out their short positions, or loan or pledge the common
stock to broker-dealers that in turn may sell these securities. The Selling
Shareholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more
derivative securities which require the delivery to such broker-dealer or other
financial institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this
prospectus (as supplemented or amended to reflect such transaction).

     The Selling Shareholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act. Each Selling Shareholder has informed us
that it does not have any written or oral agreement or understanding, directly
or indirectly, with any person to distribute the common stock. In no event shall
any broker-dealer receive fees, commissions and markups which, in the aggregate,
would exceed eight percent (8%).

     We are required to pay certain fees and expenses incurred by us incident to
the registration of the shares. We have agreed to indemnify the Selling
Shareholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.

     Because Selling Shareholders may be deemed to be "underwriters" within the
meaning of the Securities Act, they will be subject to the prospectus delivery
requirements of the Securities Act. In addition, any securities covered by a
prospectus which qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than under a prospectus. Each Selling
Shareholder has advised us that it has not entered into any written or oral
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the common stock. There is no underwriter or coordinating
broker acting in connection with the proposed sale of the common stock by the
Selling Shareholders.

     We have agreed to keep a prospectus effective until the earlier of (i) the
date on which the shares may be resold by the Selling Shareholders without
registration and without regard to any volume limitations by reason of Rule
144(e) under the Securities Act or any other rule of similar effect or (ii) all
of the shares have been sold pursuant to the prospectus or Rule 144 under the
Securities Act or any other rule of similar effect. The common stock will be
sold only through registered or licensed brokers or dealers if required under
applicable state securities laws. In addition, in certain states, the common
stock may not be sold unless it has been registered or qualified for sale in the
applicable state or an exemption from the registration or qualification
requirement is available and is complied with.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the common stock may not simultaneously engage in
market making activities with respect to the common stock for a period of two
business days prior to the commencement of the distribution. In addition, the
Selling Shareholders will be subject to applicable provisions of the Exchange
Act and the rules and regulations thereunder, including Regulation M, which may
limit the timing of purchases and sales of shares of the common stock by the
Selling Shareholders or any other person. Euroseas will make copies of any
prospectus available to the Selling Shareholders and have informed them of the
need to deliver a copy of a prospectus to each purchaser at or prior to the time
of the sale.

     In addition, BTG Investments, LLC ("BTG"), a wholly owned affiliate of Roth
Capital LLC ("Roth Capital"), purchased shares and warrants in our Private
Placement on August 25, 2005 (the "BTG Shares"). Under NASD rules, neither BTG
nor Roth Capital will be permitted to re-sell the BTG Shares until 180 days
after the date of the first sale of common stock registered pursuant to our
registration statement on Form F-1 (File No. 333-129145).

                       ENFORCEABILITY OF CIVIL LIABILITIES

     We are a Marshall Islands company and our executive offices are located
outside of the United States of America in Maroussi, Greece. Some of our
directors and officers and some of the experts named herein reside outside the
United States of America. In addition, a substantial portion of our assets and
the assets of our directors, officers and experts are located outside of the
United States of America. As a result, you may have difficulty serving legal
process within the United States of America upon us or any of these persons. You
may also have difficulty enforcing, both in and outside the United States of
America, judgments you may obtain in United States of America courts against us
or these persons in any action, including actions based upon the civil liability
provisions of United States of America federal or state securities laws.
Furthermore, there is substantial doubt that the courts of the Marshall Islands
or Greece would enter judgments in original actions brought in those courts
predicated on United States of America federal or state securities laws.

                    WHERE YOU CAN FIND ADDITIONAL INFORMATION

     As required by the Securities Act, we filed a registration statement
relating to the securities offered by this prospectus with the SEC. This
prospectus is a part of that registration statement, which includes additional

Government Filings

     We file annual and special reports within the SEC. You may read and copy
any document that we file at the SEC's Public Reference Room at 100 F Street,

Information Incorporated by Reference

     The SEC allows us to "incorporate by reference" information that we file

file later with the SEC prior to the termination of this offering will also be
considered to be part of this prospectus and will automatically update and
supersede previously filed information, including information contained in this

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 6. Indemnification of Directors and Officers.

     The Bylaws of the Registrant provide that any person who is or was a
director or officer of the Registrant, or is or was serving at the request of
the Registrant as a director or officer of another, partnership, joint venture,
trust or other enterprise, shall be entitled to be indemnified by the Registrant
upon the same terms, under the same conditions, and to the same extent as
authorized by Section 60 of the Business Corporations Act (Part I of the
Associations Law) of the Republic of the Marshall Islands, if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Registrant, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.

     Section 60 of the Business Corporations Act (Part I of the Associations
Law) of the Republic of the Marshall Islands provides as follows:

     Indemnification of directors and officers.

     (1) Actions not by or in right of the corporation. A corporation shall have
     power to indemnify any person who was or is a party or is threatened to be
     made a party to any threatened, pending or completed action, suit or
     proceeding whether civil, criminal, administrative or investigative (other
     than an action by or in the right of the corporation) by reason of the fact
     that he is or was a director or officer of the corporation, or is or was
     serving at the request of the corporation as a director or officer of
     another corporation, partnership, joint venture, trust or other enterprise,
     against expenses (including attorneys' fees), judgments, fines and amounts
     paid in settlement actually and reasonably incurred by him in connection
     with such action, suit or proceeding if he acted in good faith and in a
     manner he reasonably believed to be in or not opposed to the best interests
     of the corporation, and, with respect to any criminal action or proceeding,
     had no reasonable cause to believe his conduct was unlawful. The
     termination of any action, suit or proceeding by judgment, order,
     settlement, conviction, or upon a plea of no contest, or its equivalent,
     shall not, of itself, create a presumption that the person did not act in
     good faith and in a manner which he reasonably believed to be in or not
     opposed to the best interests of the corporation, and, with respect to any
     criminal action or proceeding, had reasonable cause to believe that his
     conduct was unlawful.

     (2) Actions by or in right of the corporation. A corporation shall have the
     power to indemnify any person who was or is a party or is threatened to be
     made a party to any threatened, pending or completed action or suit by or
     in the right of the corporation to procure judgment in its favor by reason
     of the fact that he is or was a director or officer of the corporation, or
     is or was serving at the request of the corporation as a director or
     officer of another corporation, partnership, joint venture, trust or other
     enterprise against expenses (including attorneys' fees) actually and
     reasonably incurred by him or in connection with the defense or settlement
     of such action or suit if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation and except that no indemnification shall be made in respect of
     any claim, issue or matter as to which such person shall have been adjudged
     to be liable for negligence or misconduct in the performance of his duty to
     the corporation unless and only to the extent that the court in which such
     action or suit was brought shall determine upon application that, despite
     the adjudication of liability but in view of all the circumstances of the
     case, such person is fairly and reasonably entitled to indemnity for such
     expenses which the court shall deem proper.

     (3) When director or officer is successful. To the extent that director or
     officer of a corporation has been successful on the merits or otherwise in
     defense of any action, suit or proceeding referred to in subsections (1) or
     (2) of this section, or in the defense of a claim, issue or matter therein,
     he shall be indemnified against expenses (including attorneys' fees)
     actually and reasonably incurred by him in connection therewith.

     (4) Payment of expenses in advance. Expenses incurred in defending a civil
     or criminal action, suit or proceeding may be paid in advance of the final
     disposition of such action, suit or proceeding as authorized by the board
     of directors in the specific case upon receipt of an undertaking by or on
     behalf of the director or officer to repay such amount if it shall
     ultimately be determined that he is not entitled to be indemnified by the
     corporation as authorized in this section.

     (5) Indemnification pursuant to other rights. The indemnification and
     advancement of expenses provided by, or granted pursuant to, the other
     subsections of this section shall not be deemed exclusive of any other
     rights to which those seeking indemnification or advancement of expenses
     may be entitled under any bylaw, agreement, vote of stockholders or
     disinterested directors or otherwise, both as to action in his official
     capacity and as to action in another capacity while holding such office.

     (6) Continuation of indemnification. The indemnification and advancement of
     expenses provided by, or granted pursuant to, this section shall, unless
     otherwise provided when authorized or ratified, continue as to a person who
     has ceased to be a director, officer, employee or agent and shall inure to
     the benefit of the heirs, executors and administrators of such a person.

     (7) Insurance. A corporation shall have power to purchase and maintain
     insurance on behalf of any person who is or was a director or officer of
     the corporation or is or was serving at the request of the corporation as a
     director or officer against any liability asserted against him and incurred
     by him in such capacity whether or not the corporation would have the power
     to indemnify him against such liability under the provisions of this
     section.

Item 7.  Recent Sales of Unregistered Securities

     On August 25, 2005, Euroseas raised approximately $21 million in gross
proceeds from a private placement transaction of its securities to a number of
institutional and accredited investors. In the private placement, Euroseas
issued 7,026,993 shares of common stock at a price of $3.00 per share, as well
as warrants to purchase an additional 1,756,743 shares of common stock. The
warrants have a five year term and an exercise price of $3.60. All of such
shares were issued, and the warrants were granted, in transactions exempt from
the registration requirements under the Securities Act of 1933, as amended,
pursuant to Section 4(2) thereof and pursuant to Rule 506 of Regulation D. In
particular, there were not more than 35 purchasers of securities and each
purchaser represented that it was either (i) an "accredited investor" as defined
in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or
(ii) a "qualified institutional buyer" as defined in Rule 144A(a) under the
Securities Act. Each purchaser further represented that it had such knowledge
and experience in financial and business matters that it was capable of
evaluating the merits and risks of the prospective investment. Finally, each
purchaser acknowledged that it was not purchasing the securities as a result of
any advertisement, article, notice or other communication regarding the
securities published in any newspaper, magazine or similar media or broadcast
over television or radio or presented at any seminar or any other general
solicitation or general advertisement. Euroseas filed a Form D with the
Commission with respect to this private placement.

Item 9. Undertakings.

(a)  Rule 415 Offering.

The undersigned Registrant hereby undertakes:

(1)  To file, during any period in which offers or sales are being made, a
     post-effective amendment to this registration statement:

     (i)  To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933, as amended (the "Act");

     (ii) To reflect in the prospectus any facts or events arising after the
          effective date of the registration statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement; and

     (iii) To include any material information with respect to the plan of
          distribution not previously disclosed in the registration statement or
          any material change to such information in the registration statement.

(2)  That, for the purpose of determining any liability under the Securities Act
     of 1933, each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.

(3)  To remove from registration by means of a post-effective amendment any of
     the securities being registered which remain unsold at the termination of
     the offering.

(4)  To file a post-effective amendment to the registration statement to include
     any financial statements required by ss.210.3-19 of Regulation S-X at the
     start of any delayed offering or throughout a continuous offering.
     Financial statements and information otherwise required by Section 10(a)(3)
     of the Act need not be furnished, provided, that the registrant includes in
     the prospectus, by means of a post-effective amendment, financial
     statements required pursuant to this paragraph (a)(4) and other information
     necessary to ensure that all other information in the prospectus is at
     least as current as the date of those financial statements. Notwithstanding
     the foregoing, with respect to registration statements on Form F-3, a
     post-effective amendment need not be filed to include financial statements
     and information required by Section 10(a)(3) of the Act or Rule 3-19 of
     this chapter if such financial statements and information are contained in
     periodic reports filed with or furnished to the SEC by the registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934, as amended (the "Exchange Act"), that are incorporated by reference
     in the Form F-3.

(5)  Each prospectus filed pursuant to Rule 424(b) as part of a registration
     statement relating to an offering, other than registration statements
     relying on Rule 430B or other than prospectuses filed in reliance on Rule
     430A, shall be deemed to be part of and included in the registration
     statement as of the date it is first used after effectiveness. Provided,
     however, that no statement made in a registration statement or prospectus
     that is part of the registration statement or made in a document
     incorporated or deemed incorporated by reference into the registration
     statement or prospectus that is part of the registration statement will, as
     to a purchaser with a time of contract of sale prior to such first use,
     supersede or modify any statement that was made in the registration
     statement or prospectus that was part of the registration statement or made
     in any such document immediately prior to such date of first use.

(6)  That for the purpose of determining liability of the registrant under the
     Act to any purchaser in the initial distribution of the securities:

     The undersigned registrant undertakes that in a primary offering of
     securities of the undersigned registrant pursuant to this registration
     statement, regardless of the underwriting method used to sell the
     securities to the purchaser, if the securities are offered or sold to such
     purchaser by means of any of the following communications, the undersigned
     registrant will be a seller to the purchaser and will be considered to
     offer or sell such securities to such purchaser:

     (i)  Any preliminary prospectus or prospectus of the undersigned registrant
          relating to the offering required to be filed pursuant to Rule 424;

     (ii) Any free writing prospectus relating to the offering prepared by or on
          behalf of the undersigned registrant or used or referred to by the
          undersigned registrant;

     (iii) The portion of any other free writing prospectus relating to the
          offering containing material information about the undersigned
          registrant or its securities provided by or on behalf of the
          undersigned registrant; and

     (iv) Any other communication that is an offer in the offering made by the
          undersigned registrant to the purchaser.

(b)  Filings incorporating subsequent Exchange Act documents by reference.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Act, each filing of the registrant's annual
report pursuant to Section 13(a) or 15(d) of the Exchange Ac (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

(e)  Incorporated annual and quarterly reports.

     The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X is not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.

(h)  Request for acceleration of effective date or filing of registration
statement on Form S-8.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing this Post-Effective Amendment No. 1 to Form F-1 and has
duly caused this Post-Effective Amendment No. 1 to the Registration Statement to
be signed on its behalf by the undersigned, thereunto duly authorized, in the
City of Maroussi, Country of Greece on September 12, 2006.
