America upon surrender of this Warrant  Certificate  and payment of the Exercise
Price at the  office or agency of the  Warrant  Agent,  but only  subject to the
conditions  set forth  herein and in the  Warrant  Agreement  referred to on the
reverse  hereof.  The Exercise Price and number of Warrant Shares  issuable upon
exercise  of the  Warrants  are subject to  adjustment  upon the  occurrence  of
certain events set forth in the Warrant Agreement.

         No Warrant may be exercised before the Exercisability  Date. No Warrant
may be exercised  after 5:00 p.m., New York City Time, on December 14, 2003, and
to the extent not exercised by such time such Warrants shall become void.

         Reference  is  hereby  made  to  further  provisions  of  this  Warrant
Certificate set forth on the reverse hereof,  which further provisions shall for
all purposes have the same effect as though fully set forth at this place.

Warrant Agent, as such term is used in the Class A Warrant Agreement.

         This  Warrant  Certificate  shall  be  governed  by  and  construed  in

Seabulk International, Inc.
READ CAREFULLY

   Because vessels owned by Seabulk International,  Inc. (the "Company") and its
subsidiaries  operate in the United States coastwise  trades,  United States law
provides that no more than 25 percent of its stock may be owned or controlled by
Non-Citizens, as defined in the Application for Purchase of Common Stock printed
below  on this  Certificate.  Under  the  Certificate  of  Incorporation  of the
Company,  the maximum percentage of the total outstanding shares of common stock
of the Company that may be owned by Non-Citizens is 24.99%.  Any purported sale,
transfer or other  disposition to  Non-Citizens  of shares of common stock which
would result in increasing  the ownership of shares by  Non-Citizens  above such
maximum  permitted  percentage  shall be  ineffective  as against the Company to
transfer the shares or any voting or other rights in respect  thereof,  and such
transfer shall not be recorded on the books of the Company in any such case, and
neither  the  Company  nor the  transfer  agent for the  common  stock  shall be
required to  recognize  the  transferee  or  purported  transferee  thereof as a
stockholder  of the  Company  for any  purpose  whatsoever  except to the extent
necessary to effect any remedy  available  to the Company.  Each share of common
stock  issued  by the  Company  shall be  represented  by either  CITIZEN  SHARE
CERTIFICATES  or  NON-CITIZEN  SHARE  CERTIFICATES,  and shall be subject to the
limitations  set  forth  thereon.   Any  shares  represented  by  CITIZEN  SHARE
CERTIFICATES  held in the names of or for the account of Non-Citizens  will have
no rights, and the Company may regard any certificate  representing such shares,
whether or not validly issued, as having been invalidly issued. The Company will
furnish to any Warrant holder,  upon written request and without charge,  copies
of the applicable provisions of the Certificate of Incorporation of the Company.
Any such request may be addressed to the Company.  The shares of common stock to
be purchased pursuant to this Warrant will be issued on the books of the Company
only if the  Application  for  Purchase of Common Stock set forth below has been
executed by the purchaser and the Company determines that such issuance will not
cause the  percentage  ownership of common stock by  Non-Citizens  to exceed the
maximum permitted percentage.
