Almost all boats benefit from upgrading to a full battened mainsail, but which benefits are most important to you, depends upon the type of sailing you enjoy. Increased sail area: Full length battens allow the mainsail's roach to be increased, improving light air performance. Controls flogging: Makes for more comfortable heavy air sailing and increases sail life. Stabilised sail shape: Sail draft is held forward as apparent wind increases, creating more forward drive and less heeling. Easier sail handling: When combined with lazy jacks, lowering and reefing can be controlled from the cockpit. Lighter sailcloth: Full battens support the cloth on the bias making sails stronger therefore lighter fabrics can be used for cruising applications. The principle behind Bainbridge International's SAILMAN systems is simple.
