International Yacht Tonnage Measurement

Tonnage measurement for international yacht registration

Global Yacht Surveyor works with international yacht owners, including North American buyers, and the brokers, closing agents and registration professionals handling their transactions. Whether you are purchasing a yacht, registering it for the first time or changing flag, Tony helps coordinate the tonnage measurement with your registration and closing timetable.

Tonnage records a vessel’s size under the applicable measurement rules; it is different from the yacht’s weight or displacement. The work needed depends on the vessel and registration route.
