Boat with sails formed of vertical panels - has vertical panels held to mast by horizontal ties and rotatable about longitudinal axes to give curved appearance to sail

摘要

The sails are made from panels (13) which have parallel sides and a high aspect ratio. The panels are supported against a mast (14) and have some horizontal ties (16) to hold them to the mast. The panels are supported from a boom (15). The panels are capable of rotating about their longitudinal vertical axes, and each may be altered by a different amount, so that the combined sail may have a curved appearance. A control system may be regulated automatically from a central point on the vessel. The sails may be distributed along the centre line of the vessel which may have several masts.
