Abstract
During the last decade the civil and military applications of catamaran vessels have developed rapidly. Their particular area of proliferation is the short sea shipping where their power, economy, habitability and behavior have provided them a market niche. The rapid market growth ha caused catamarans to experience design modifications regarding size, speed, cargo diversity (passengers, vehicles, containers). The purpose of this article is to show the work developed by the El Pardo Hydrodynamic Experiences Channel (CEHIPAR) regarding the propulsive qualities of catamaran vessels. This work is the result of the need expressed by the Ministry of Defense for provision of technical assistance and scientific research for an I+D program that established more adequate program parameters for a catamaran-type vessel from the propulsive point of view, in relation to its size and shape, so that it has the adequate information and trustworthiness when suggesting a vessel of this type as an alternative to other platforms, always within the scope of application of patrol-type or quick-attack-type vessels.

William Dampier, captain of an English vessel, occasional buccaneer and corsair, while at the same time an excellent writer, botanist and scientific observer, was the first British national to explore and map the coasts of New Holland and New Guinea, circumnavigating the world up to two times.Way back in 1697, travelling through the southwestern coast of India searching for business opportunities he found a sort of vessel, built with little more than bound logs which he described as :”...at the Coast of Malabar there are vessels they call catamarans

Canal de Experiencias Hidrodinámicas de El Pardo (CEHIPAR), an Autonomous State Entity, internationally renowned in the area of hydrodynamics, that carries out projects, experiments and research for shipyards, shipping agencies, engineering offices, manufacturers and individuals, has been in charge in this case of compiling and classifying all the necessary information regarding bottom data and towing tests
Summary
Way back in 1697, travelling through the southwestern coast of India searching for business opportunities he found a sort of vessel, built with little more than bound logs which he described as :”...at the Coast of Malabar there are vessels they call catamarans. The first documented catamaran in modern Europe, designed in 1662 as a member of the William Petty Royal Society was conceived so it could travel faster in shallow waters [7], with less wind and crew than other vessels of the time. Skepticism made it commercially unsuccessful, remaining an unused idea in the West for another 200 years
