Canadian Tonnage Measurement for Canadian Documentation

We are one of only two companies recognised to provide tonnage measurement who are based in the Caribbean.

The Tonnage Measurement Survey is quite different from a Condition Survey.

The Tonnage Survey is carried our by a complicated series of measurements which are used to evaluate the internal volume of the hull and deck structure. There are various areas which are excluded from the tonnage, such as toilets if they are above the tonnage deck. The tonnage is used by the Port Authorities to levee harbour fees etc.

Before you request a Tonnage Survey, you should contact the port where you want the vessel to be registered and confirm that the name is available. We can then carry out the survey.

The survey can usually be carried out afloat, provided there is access to the hull interior throughout the vessel. In some instances you may be asked to provide plans of the vessel or, in rare cases, to haul the vessel.

The survey will probably take about 4 hours for a 50' boat. We then retire to the computer to work out the formula. You do not get a copy of the form. We send the forms, photographs, drawings of the plan view, end and side elevations to Transport Canada.

If your boat is 14 meters LOA or less and a monohull, you can do the measurement yourself with a simplified format. Our fees vary with the size of the vessel but for a normal monohull vessel less than 25 tons (most sailing boats less than 45�) we charge US$650.00 plus any travel time at US$150.00 per hour. We charge US$950.00 for catamarans, less than 24m. Canadian Tonnage measurements have to be done with the vessel out of the water. We usually do not charge travel time for vessels on Tortola.
