(Bahamas)  Limited  ("Amendment  No. 2") does not relate to the  contents of the

Restated  Articles  of  Association  of  the  Company  as  Exhibits  1 and  3.1,

PART II
INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 6. Indemnification of Directors and Officers.

The articles of association of the Registrant and the International Business
Companies Act, 2000 of the Commonwealth of The Bahamas, or the IBCA, provide for
indemnification of every director and officer of the Registrant out of the funds
of the Registrant. The indemnification provisions of the articles of
associations provide as follows:

(1) Actions by Others. The Registrant (a) will 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 Registrant) by
reason of the fact that he is or was a director or an officer of the Registrant
and (b) except as otherwise required by paragraph (3) below, may 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 Registrant) by reason of the fact that he is or was an employee or
agent of the Registrant, or is or was serving at the request of the Registrant
as a director, officer, employee, agent of or participant in another person,
against expenses (including attorneys' fees), judgments, fines and amounts
actually and reasonably incurred by such person in connection with such action,
suit or proceeding if he acted honestly and in good faith with a view 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. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, will not, of
itself, create a presumption that the person did not act honestly and in good
faith with a view to the best interests of the Registrant, and, with respect to
any criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.

(2) Actions by or in the Right of the Registrant. The Registrant will 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
Registrant to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the Registrant, or is or was
serving at the request of the Registrant as a director, officer, employee, agent
of or participant in another person against expenses (including attorneys' fees)
actually and reasonably incurred by such person in connection with the defense
or settlement of such action or suit if he acted honestly and in good faith with
a view to the best interests of the Registrant and except that no
indemnification will be made in respect of any claim, issue or matter as to
which such person have been adjudged to be liable for negligence or misconduct
in the performance of his duty to the Registrant unless and only to the extent
that the court in which such action or suit was brought will 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 such court will deem proper.

(3) Successful Defense. To the extent that a person who is or was a director,
officer, employee or agent of the Registrant has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in
paragraph (1) or paragraph (2) above, or in defense of any claim, issue or
matter therein, such person will be indemnified through the use of Registrant
funds against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

(4) Specific Authorization. Any indemnification under paragraph (1) or paragraph
(2) above (unless ordered by a court) will be made by the Registrant only as
authorized in the specific case upon a determination that indemnification of the
director, officer, employee or agent is proper in the circumstances because such
person has met the applicable standard of conduct set forth in said paragraph
(1) and (2) above. Such determination will be made (a) by the board of directors
by a majority vote of a quorum consisting of the directors who were not parties
to such action, suit or proceeding, or (b) if such a quorum is not obtainable,
or, even if obtainable a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion, or (c) by the shareholders of
the Registrant.

(5) Advance of Expenses. Expenses incurred by any person who may have a right of
indemnification under the articles of association of the Registrant in defending
a civil or criminal action, suit or proceeding may be paid by the Registrant 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, officer, employee or agent to repay
such amount unless it will ultimately be determined that he is entitled to be
indemnified by the Registrant pursuant to the indemnification provisions of the
articles of association.

(5) Right of Indemnity not Exclusive. The indemnification provided by the
indemnification provisions of the articles of association is not deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any provision of the articles of association, agreement, vote of
shareholders or disinterested directors of the Registrant or otherwise, both as
to action in his official capacity and as to action in another capacity while
holding such office, and will continue as to a person who has ceased to be a
director, officer, employee or agent and will inure to the benefit of the heirs,
executors and administrators of such a person.

(6) Insurance. The Registrant may purchase and maintain insurance on behalf of
any person who is or was a director, officer, employee or agent of the
Registrant, or is or was serving at the request of the Registrant as a director,
officer, employee or agent of or participant in another person against any
liability asserted against him and incurred by him in any such capacity, or
arising out of such person's status as such, whether or not the Registrant would
have the power to indemnify him against such liability under the indemnification
provisions of the articles of association.

Section 57 of the IBCA provides as follows:

Indemnification

(1) Subject to subsection (2) and any limitations in its memorandum or articles
of association in any unanimous shareholder agreement, a company incorporated
under the IBCA may indemnify against all expenses, including legal fees, and
against all judgments, fines and amounts paid in settlement and reasonably
incurred in connection with legal or administrative proceedings any person who:

     (a)  is or was a party or is threatened to be made a party to any
          threatened, pending or completed proceedings, whether civil or
          administrative by reason of the fact that the person is or was a
          director, an officer or a liquidator of the company; or

     (b)  is or was, at the request of the company, serving as a director,
          officer or liquidator, or in any other capacity is or was acting for,
          another company or a partnership, joint venture, trust or other
          enterprise.

(2) Subsection (1) only applies to a person if the person acted honestly and in
good faith with a view to the best interests of the company.

Section 58 of the IBCA allows for directors' and officers' insurance to be
purchased by the Registrant and provides as follows:

Insurance

A company incorporated under IBCA may purchase and maintain insurance in
relation to any person who is or was a director, a registered agent, an officer
or a liquidator of the company, or who at the request of the company is or was
serving as a director, a registered agent, an officer or a liquidator of, or in
any other capacity is or was acting for, another company or a partnership, joint
venture, trust or other enterprise, against any liability asserted against the
person and incurred by the person in that capacity, whether or not the company
has or would have had the power to indemnify the person against the liability
under subsection (1) of Section 57 of the IBCA, described above.

Item 7. Recent Sales of Unregistered Securities.

In November 2004, we issued $180,000 of 9% First Preferred Ship Mortgage Notes
due 2014, or the Notes. The Notes were issued pursuant to the exemption under
Section 4(2) of the Securities Act. The proceeds of the Notes offering were used
principally to prepay the $135,000 of 10 1/2% First Preferred Ship Mortgage
Notes due 2008 we issued in 1998, or the Prior Notes, and to buy an additional
Ocean Business asset, further invest in our River Business and to diversify into
the Passenger Business with the acquisition of two passenger vessels.

In the first quarter of 2005, pursuant to a registration rights agreement, we
completed a registered exchange offer in which we exchanged registered Notes for
the Prior Notes in order to allow the Notes to be eligible for trading in the
public markets. Credit Suisse First Boston acted as underwriter for the issuance
and exchange of the Notes.

Item 9.      Undertakings.

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;

     (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. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b)
          (ss.230,424(b) of this chapter) if, in the aggregate, the changes in
          volume and price represent no more than a 20% change in the maximum
          aggregate offering price set forth in the "Calculation of Registration
          Fee" table in the effective registration statement;

    (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;

     Provided, however, That:

          (A) Paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply
          if the registration statement is on Form S-8 (ss.239.16b of this
          chapter), and the information required to be included in a
          post-effective amendment by those paragraphs is contained in reports
          filed with or furnished to the Commission by the registrant pursuant
          to section 13 or section 15(d) of the Securities Exchange Act of 1934
          (15 U.S.C. 78m or 78o(d)) that are incorporated by reference in the
          registration statement; and

          (B) Paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section
          do not apply if the registration statement is on Form S-3 (ss.239.13
          of this chapter) or Form F-3 (ss.239.33 of this chapter) and the
          information required to be included in a post-effective amendment by
          those paragraphs is contained in reports filed with or furnished to
          the Commission by the registrant pursuant to section 13 or section
          15(d) of the Securities Exchange Act of 1934 that are incorporated by
          reference in the registration statement, or is contained in a form of
          prospectus filed pursuant to Rule 424(b) (ss.230.424(b) of this
          chapter) that is part of 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)  If the registrant is a foreign private issuer, to file a post-effective
     amendment to the registration statement to include any financial statements
     required by Item 8.A of Form 20-F (17 CFR 249.220f) 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 (ss.239.33 of this chapter), a
     post-effective amendment need not be filed to include financial statements
     and information required by Section 10(a)(3) of the Act or ss.210.3-I9 of
     this chapter if such financial statements and information are contained in
     periodic reports filed with or furnished to the Commission by the
     registrant pursuant to section 13 or section 15(d) of the Securities
     Exchange Act of 1934 that are incorporated by reference in the Form F-3.

(5)  That, for the purpose of determining liability under the Securities Act of
     1933 to any purchaser:

     (i)  If the registrant is relying on Rule 430B (ss.230.430B of this
          chapter):

     (A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3)
     (ss.230.424(b)(3) of this chapter) shall be deemed to be part of the
     registration statement as of the date the filed prospectus was deemed part
     of and included in the registration statement; and

     (B) Each prospectus required to be filed pursuant to Rule 424(b)(2),
     (b)(5), or (b)(7) (ss.230.424(b)(2), (b)(5), or (b)(7) of this chapter) as
     part of a registration statement in reliance on Rule 430E relating to an
     offering made pursuant to Rule 4l5(a)(1)(i), (vii), or (x)
     (ss.230.415(a)(1)(i), (vii), or (x) of this chapter) for the purpose of
     providing the information required by section 10(a) of the Securities Act
     of 1933 shall be deemed to be part of and included in the registration
     statement as of the earlier of the date such form of prospectus is first
     used after effectiveness or the date of the first contract of sale of 314
     securities in the offering described in the prospectus. As provided in Rule
     430B, for liability purposes of the issuer and any person that is at that
     date an underwriter, such date shall be deemed to be a new effective date
     of the registration statement relating to the securities in the
     registration statement to which that prospectus relates, and the offering
     of such securities at that time shall be deemed to be the initial bona fide
     offering thereof. 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 effective date, 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 effective date; or

     (ii) If the registrant is subject to Rule 430C (ss.230.430C of this
          chapter), 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 (ss.230.430A of this
          chapter), 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
     Securities Act of 1933 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
