Abstract: The invention relates to a sailing craft that comprises: two hulls (1) having a transverse cross-section (S1) that is constant on at least ¼ of the length thereof and having planar rear edges oriented along said section; two tubes or profiles (2) transversally secured to the hulls in the catamaran configuration or longitudinally secured to the hulls joined back-to-back in the pirogue configuration; six attachment points (3) on each hull for enabling the assembly of the two configurations and to enable a rapid conversion from a catamaran sailing craft into a pirogue rowing craft.
