ABSTRACT:
High performance sailing yacht designs are disclosed based on a keelless sailing yacht concept having fore and aft cambered foils for leeway control which foils replace the function of the standard keel. A keelless sailing yacht of this type is disclosed with dynamic ballast which is laterally movable to apply a variable counter-heeling force; a tiltable mast which may have a rotatable mast and sail leading edge; cambered foils for cyclic and collective steering; and adjustable camber controls for adjusting lift and leeway. The foregoing features allow disclosed improvements and modifications to hull design in having a duplex hull form, with lower and upper hull shapes, the lower of low drag shape, and of reduced section, while the upper hull extends laterally abeam from the lower hull for added buoyancy when heeled and for accommodation room.
