A canting ballast twin foil (CBTF) sailing yacht constructed according to the invention includes a sailing hull, a ballast, a ballast-supporting structure, and an onboard ballast drive system. The ballast drive system moves the ballast in order to vary the counter-heeling force it produces underway.
A canting ballast twin foil (CBTF) sailing yacht constructed according to the invention includes a sailing hull, a ballast, a ballast-supporting structure, and an onboard ballast drive system. The ballast drive system moves the ballast in order to vary the counter-heeling force it produces underway. Twin foils that depend downwardly from the hull in positions fore and aft of the ballast provide leeway and steering control. An onboard main engine drive system provides power, either directly by suitable mechanical coupling or indirectly through charging of the battery/electric system, for one or more of a canting system, a leeway, and/or steering control system. The onboard main engine drive system may also power a yacht-propelling propeller.
