A 1966 study on the relationship between resistance and speed of sailing yachts with a variety of hull shapes by a Dutch group analyzed 22 models. Nine models were analyzed in cooperation with M.I.T. in Boston. Another 13 model tests were completed and analyzed in Delft. The speed of a sailing yacht depends on the strength and direction of the wind, in addition to its own characteristics. Tests were carried out to determine wind and hydrodynamic data for a variety of sailing forces, which led to sail force coefficients used to calculate yacht speeds. Course stability and traverse stability were also examined. The results of the study form the basis for the new International Measurement System, a handicap system used to calculate the impact of prevailing wind strength on speed in competition sailing yachts.
