Sails, in particular for a boat 1, formed by a sail 5 which is mounted on a rigging 2-6 and which thus forms a hollow, characterised by the presence of at least one member for taking up the hollow consisting of two lips 16-17 fixed to the sail 5 so as to define a zone in the shape of an elongate panel 18 and by means 20 for moving these lips together and holding them together. The means for moving together may consist of a zip fastener. Such sails allow the navigator to adapt the hollow of the sail to the force of the wind and avoid any difficulty in rolling. <IMAGE>
