Sail battens for profiling sails for wind-driven vessels are known. They are made of an elastic material so that the battens have a suitable bending curve under predetermined loading. The known sail battens have the disadvantage that a change in wind pressure changes the bending curve and thus the aerodynamic profile of the sail - an undesirable change for the most part. The object of the invention is to create a dimensionally stable sail batten. This is achieved by the sail batten consisting of batten pieces which are connected to one another by articulated joints. The articulated joints can only be moved in a predetermined angular range and thus form with the batten pieces a sail batten which is also dimensionally stable during changes in the wind pressure.
