Abstract

The sail (1) consists of two panels formed by an outer strip so as to form an inflatable profile having an aerofoil shape. The sail is inflated through a side valve and has the leading edge fixed to the mast (9). The sail may be divided into a number of panels, inflated separately. The leech of the sail (3) consists of plain canvas or fabric behind the inflatable luff portion (2). The mast is supported by standing rigging (24) which avoids contact with the sail. The elements may be joined together by means of adhesive on the material.
