Windsurfing rigs have by nature an elastic, living character... the aerodynamic form your rig presents to the wind depends primarily on three elements: -sail design (the mast and seam curves cut into the sail) -mast stiffness & flex character -the trim you set into your rig (downhaul & outhaul tension as well mast-foot position and boom-height among other trim settings). Trim sensitivity = Performance & wind range expansion Rig trim is critical to rig performance. Loftsails are exceptionally trim Trim begins with noting the boom length, mast length and the recommended mast for your sail...

Extreme low wind trim will increase light wind power and also make the rig feel stiff and more back hand oriented, especially should the wind rise. Greater outhaul tension flattens the sail profile making the sail much easier to handle and faster in medium and strong winds. Flatter outhaul trim allows the sail to pass more easily through the wind. For a given sail size the range between ideal strong and light wind trim may be up to An easy trim reference (cam-free sails) is the position of the forward end of the batten just above the boom. If this forward batten end passes the mast without...

Narrow harness lines (12cm and less) transfer power to the sailor more directly, more critically. As the harness lines are placed closer together on the boom they make rig trim more critical relative to the power center. Racers tend to set narrow harness line placement, often no space -Harness line length also influences performance. For average size windsurfers 24 to 26 cm from the line center to the boom is an average harness line length. Short lines limit speed potential... bodyweight is the power generator. Bodyweight too close to the rig and maximum power is unavailable. Overly short...

mast pocket, the sail head arrives all the way to the mast top before pulling the sail all the way down onto the mast. A fold will occur at the boomhole, which relieves pressure between the mast pocket and the mast top- avoiding damage to the mast pocket. -It is also very important that the mast parts do not slide apart during the rigging process. If your mast has a loose fit, check the joint before downhauling by feeling the middle of the mast with your hand- if you can feel a gap between the mast parts- STOP!... and re-fit your mast! Taping your mast together around the middle seam will...

High wind trim package If you feel overpowered set the mast and boom length to the recommended high-wind lengths and trim accordingly. Also try the boom lower by 2-4 cm and set the mastfoot further forward 1 -3cm. Hi wind trim will require the harness lines to move forward by 2-4cm compared to Low wind trim package To trim for power free the downhaul and the boom 2-4cm. Raise the boom a few centimeters and move the mastfoot back 2-3 cm. Low wind trim will require the harness lines to move back by 2-4cm compared to high wind trim. Experience the new sensations resulting from trim...
