FSL – Furling Structure Luff – This is a completely new line of furled downwind sails in our offer. It is a new type of sail in which the luff design eliminates the heavy anti-torsion rope needed in traditional furling. The sail construction uses unidirectional, continuous yarns which transfer the load from tack to head along the natural line of stress distribution, thanks to which the sail does not require huge stresses on the halyard as in case of sails with anti-torsion rope. FSL sails can have up to 30% less luff tension than AT rope sails, making these sails lighter, safer and easier to handle.
