What is the difference between GT and NT?
Gross tonnage (GT) is a function of the volume of all of a ship’s enclosed spaces (from keel to funnel) measured to the outside of the hull framing. Net tonnage (NT) is based on a calculation of the volume of all cargo spaces of the ship.
What is the difference between gross tonnage and gross registered tonnage?
Gross tonnage is calculated based on “the moulded volume of all enclosed spaces of the ship” and is used to determine things such as a ship’s manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces.
What is the difference between gross tonnage and deadweight?
Deadweight Tonnage: expresses the number of tons of 2,240 pounds that a vessel can transport of cargo, stores, and bunker fuel. Gross Tonnage: applies to vessels, not to cargo. It is determined by dividing by 100 the contents, in cubic feet, of the vessel’s closed-in spaces. A vessel ton is 100 cubic feet.
How do you calculate gross vessel tonnage?
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.

Tonnage Length means 96% of the total length on a waterline of a ship at 85% of the least moulded depth measured from the top of the keel, or the length from the fore-side of the stem to the axis of the rudder stock on that waterline, if that be greater.
