Clause 30

Every registered mortgagee shall have power absolutely to dispose of the ship or share in respect of which he is registered, and to give effectual receipts for the purchase money; but where there are more persons than one registered as mortgagees of the same ship or share, a subsequent mortgagee shall not, except under the order of the High Court, sell the ship or share without the concurrence of every prior mortgagee.

Every registered mortgagee shall be entitled to enforce his mortgage by an action in rem in admiralty whenever any sum secured by the mortgage is unpaid when due or otherwise in accordance with the terms of any deed or instrument collateral to the mortgage.
