Choosing the right headsail LP (Luff-Perpendicular) depends on several things. When, where, and why you are sailing, as well as your rig set-up and limitations. The most versatile LP% is 135%. Your sailing destination and conditions and rig type help decide what size of headsail LP to choose. The type of sailing, racing, or cruising sailing, also factors in when choosing a headsail LP percentage. Give Precision Sails a call and we can help you out!
