All international sailing boats over 3 m in length (and vessels shorter than 3 m that glide such as jet skis and powerboats) together with all sailing boats with an engine capacity of over 4 KW must be declared in the Port branch office, whether it arrived by sea or by land.

Should there be no vessel registration document, the Harbour Master's Office will perform and charge for a spot check of the small boat. An insurance policy may also be obtained from the Harbour Master's Office.
The crew list is certified by the Harbour Master's Office or the branch office. The owner of the vessel is required to report any changes in the crew list.
