Ladies and Gentlemen:

We have acted as Liberian counsel to General Maritime Corporation, a corporation organized under the laws of the Republic of the Marshall Islands (the “Company”) and each of its wholly owned Liberian subsidiaries listed in Schedule 1 hereto (the “Additional Registrants”), in connection with the Registration Statement on Form S-4, as amended (File No. 333-166280) ( the “Registration Statement “), filed by the Company with the United States Securities and Exchange Com- mission, pursuant to which the Company is registering (i) $300,000,000 aggregate  principal amount of its 12% Senior Notes due 2017 (the “Series B Notes”) to be exchanged for the Company’s outstanding notes bearing substantially identical terms and in like principal amount (the “Series A Notes”) in a registered exchange offer as contemplated by the Registration Statement and (ii) the guarantees (the “Subsidiary Guarantees”) of each of the subsidiary guarantors listed on Schedule 1 hereto (the “Subsidiary Guarantors”) of the Series B Notes.  The Series A Notes were issued, and the Series B Notes will be issued, under an Indenture dated as of November 12, 2009, among the Company, the Subsidiary Guarantors parties thereto and The Bank of New York Mellon, as trustee.

We have made such inquiries and reviewed such documents and records as we have deemed necessary or appropriate as a basis for our opinion.  We have also relied upon the statements, representations and certificates of officers or other representatives of the Additional Registrants, public officials and others.  We have not independently verified the facts so relied on.

Based on the foregoing, and subject to the qualifications, limitations and assumptions set forth herein, we are of the opinion that the Subsidiary Guarantee of each Additional Registrant has been duly authorized by such Registrant.
