Thames Measurement, also known as Thames Tonnage, is a system for measuring ships and boats. It was created by the Thames Yacht Club, and was designed for small vessels, such as yachts. It was originally used for calculating the port dues for yachts; the formula was also used in some early handicapping systems for yacht racing. It is a variation of Builder's Old Measurement.
