49. (1) Where any Registrar, not being the Registrar of the ship's port of registry, on an application as to an alteration in a ship directs the ship to be registered anew, he shall either grant a provisional Certificate of Registry describing the ship as altered or provisionally endorse the particulars of the alteration on the existing Certificate of Registry. (2) Every provisional Certificate of Registry granted, and every Certificate provisionally endorsed, under sub section (1), shall, within ten days after the first subsequent arrival of the ship at her port of registry, be delivered by the master to the Registrar, and the Registrar shall thereupon cause the ship to be registered anew. (3) The Registrar who grants provisional Certificate of Registry or provisionally endorses a Certificate under sub section (1), shall add to the Certificate or endorsement a statement that the same is provisional and shall send a report of the particulars of the case to the Registrar of ship's port of registry, containing a similar statement as the Certificate or endorsement.
