A method and a sailing boat (1) are designed for low or non-drift sailing, in which the total power provided by the sail (5) is provided and in which the effective area and/or curvature and/or angle of incidence of the keel (3) in relation to the boat's hull is/are designed to provide the optimum power, possibly taking the water flow and the boat's weight into account. To this end the keel (3) takes the form of a multi-section, unballasted fin (33) which can be completely retracted into the hull (2) and pivoted in relation to the axis (10) of the boat and the sections (34, 37, 38) of which are fitted together via hinges (35, 39) to produce a different curvature.

L'invention concerne un procédé et un voilier (1) permettant d'actionner avantageusement un voilier avec peu de dérive ou pratiquement pas de dérive. La force globale fournie par la voile (5) est détectée, puis la quille (3) est adaptée en termes de surface active et/ou de bombement et/ou de forme profilée et/ou d'angle d'incidence, par rapport à la coque, éventuellement en tenant compte de l'écoulement de l'eau et du poids du bateau, de manière à produire une force antagoniste optimisée. A cet effet, la quille (3) se présente sous forme d'empennage (33) en plusieurs parties, sans ballast, pouvant être escamoté dans sa globalité dans la coque (2), pouvant pivoter par rapport à l'axe longitudinal (10) du bateau et dont les parties (34, 37, 38) peuvent être reliées par l'intermédiaire de charnières (35, 39) de manière à former un bombement modifié.
