Article 4 - Liens on Vessels and Enforcement Thereof
84 - Assignment of Lien.

ยง 84. Assignment of lien. A lien, a notice of which has been filed
pursuant to the provisions of this article, may be assigned by a written
instrument duly acknowledged and filed in the same place where the
notice of the lien was filed. The assignment shall specify the debt upon
which the lien is founded, the date of the filing of the notice thereof
and the assignee. Such assignment and the name of the assignee shall be
entered by the clerk opposite the original entry of such lien, and after
the filing of such assignment, but not otherwise, the assignee may
enforce the lien in like manner as the assignor could have done.
