How to calculate gross tonnage of recreational vessels?
- For a boat with a simple sailing hull: Gross Tonnage = (. 5 x L x B x D) divided by 100.
- For a sailing boat with keel: Gross Tonnage = (. 375 x L x B x D) divided by 100.
- For power boats: Gross Tonnage = (. 67 x L x B x D) divided by 100.
How do they measure ships?
A ship’s Length Overall [LOA] is measured in feet and inches from the extreme forward end of the bow to the extreme aft end of the stern. Watercraft operators must be familiar with this and similar dimensions to safely maneuver the ship. The dimension is commonly found in lists of ship’s data for each vessel.

Is displacement the weight of a boat?
Boats with displacement hulls move through the water by pushing the water aside and are designed to cut through the water with very little propulsion. If you could weigh that displaced water, you would find it equals the weight of the boat. That weight is the boat’s displacement.
What is tonnage for boats?
Tonnage is a measure of the cargo-carrying capacity of a ship, and is commonly used to assess fees on commercial shipping. The term derives from the taxation paid on tuns or casks of wine. In modern maritime usage, “tonnage” specifically refers to a calculation of the volume or cargo volume of a ship.
How is boat displacement measured?
