A canting ballast twin foil (CBTF) sailing yacht constructed according to the invention includes a sailing hull, a laterally moveable ballast suspended beneath the hull that provides a counter heeling force when the yacht is underway, and fore and aft foils that provide improved leeway control and ballast. Components are included for at least partially retracting into the hull at least one of the ballast-supporting strut, the fore foil, and the aft foil.
