caption_attribution_description: English: Thames Raters near Ravens Ait on the River Thames
context_page_description: The Thames A Class Rater is both a historic and modern specialist sailing craft designed for the particular conditions at Thames Sailing Club, on the River Thames at Surbiton in England. The class is a development of the Half Rater, which was designed by Linton Hope in 1907. The rules refer to the craft as a yacht.
  The rig is lofty, supported by standing rigging and usually by runners, and the hull is a scow with metal centreplate.
  All boats built before 1922 are made from wood whilst those built since are of a different construction.
  The rater is extremely fast, planes easily, and is a technically highly challenging boat to sail in anything above moderate wind conditions. It is usually sailed with a crew of three.
  Raters have traditionally commuted by river under tow between Thames Sailing Club at Surbiton and Upper Thames Sailing Club at Bourne End, Buckinghamshire.
