Thames Measurement, also known as Thames Tonnage, is a system for measuring ships and boats. It was created in 1855 as a variation of Builder's Old Measurement by the Royal Thames Yacht Club , and was designed for small vessels, such as yachts .
100 the divisor is unitless, so tonnage would be expressed in 'ft 3 of tun'. [1] In 1678 Thames shipbuilders used a method assuming that a ship's burden would be 3/5 of its displacement. Since tonnage is calculated by multiplying length × beam × draft × block coefficient, all divided by 35 ft 3 per ton of seawater, the resulting formula ...
Tonnage is a measure of the 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.
George Moorsom ordered the entire fleet of British merchant ships to be measured according to the new System and then divided the total gross tonnage by the total registered tonnage. The result was 98.22 cubic feet (2.781 m 3 ) per gross ton, which was rounded to 100 cu ft (2.8 m 3 ) per ton.
Gross tonnage is calculated by measuring a ship's volume (from keel to funnel, to the outside of the hull framing) and applying a mathematical formula. Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. [1]
The net tonnage calculation is based on a number of factors, one of which is the moulded draft d.The choice of the value to use for d can be complicated. For ships subject to the International Convention on Load Lines, the Summer Load Line draft is used, with the exception of cases where that is a timber load line.
It was built at the Albert Yard, Cowes, for J.Howard Taylor, who later won the gold medal in the category 3 to 10 tons at the 1900 Olympics. This yacht was authentically restored between 1999 and 2003 by the Cantiere Navale dell'Argentario, in Tuscany, and is the last 19th-century Godinet rater.
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. [1]
