The yachts had to have a tonnage certificate of one ton at the most according to the Godinet rule of 1892.

This was the origin of the Suez Canal Net Tonnage and the Suez Canal Special Tonnage Certificate still used today.

In addition to the national or international tonnage certificates, Panama and Suez Canal tonnage certificates can be issued by ABS on behalf of those authorities.

It is still in use, as amended by the Rules of Navigation of the Suez Canal Authority, and is registered in the Suez Canal Tonnage Certificate.
