1. Basis, I want to learn: �Windorientation �Lift the sail and start surfing 149 L >150 L 2. Beginner, I want to learn: �Turning �Surf in all possible direction �Low-wind tack �Low-wind jibe �Using the trapeze
3. Intermediate, I want to learn: � Turning with both the sail and carve � Planing � Beachstart � Better use of trapeze � Jibe � Tack � Foot straps � Waterstart 100 L 100 -130 L F 2 BANAAN 4. Advanced, I want to learn: � Carving � Fast-tack � Planed jibe � Jumping
Choose your sail! Normal: (1. 34 * weight) / windspeed Beginner: (1. 15 * weight) / windspeed
Choose your fin! Fin length = -0. 1*surface^2 + 6. 46*surface
We want �More speed �Fast into planing �Windstoten opvangen
Trimming �Boom height �Higher, more pressure back foot: � Earlier planing � Less control � Able to sail more to the wind �Lower, more pressure front foot: � More control � Less nervous behaviour
Trimming �Fin (spin out) Longer = more lift, earlier planing, more to the wind Shorter = more control (overpowered), better jibing Thicker = more lift, earlier planing Thinner = less resistance, higher end speed Straight = more speed Curved = better jibing
Trimming �Placing the mastfoot �Frontwards: � board is less nervous => more control � earlier planing �Backwards: � Higher end speed � More nervous behaviour � More maneuverable � Possibly dragging through the water
Trimmen �Loose leach
Trimming � How strong do we pull at the mastbase (neerhaler) � Stronger: � � Flatter profile (less deep ‘belly’) More ‘loose leach’ Higher end speed More control � Weaker � Earlier planing (but lower end speed) � How strong do we pull at the boom (uithaler) � With two fingers � Pressing the sail you may just touch the boom � More wind -> pull stronger -> less deep belly -> less power
Trimming �Which hole in your sail do you use �Upper one: normal conditions �Lower one: easier overpowered (more leach)
Trimming �Trapeze lines �Middle of trapeze lines in pressure point: � Middle between your hands when holding the boom �Distance between lines: � Personal � 25 - 30 cm customary � Beginners: closer together, easier to loose wind from gusts �Line length � Personal � Too long => spin-outs
Trimming �Foot straps To the front = earlier planing, easier to get into foot straps To the back = higher end speed To the middle = easer to get into and stay in the straps, more control over your board (freestyle) More outside = higher speed Far from each other = more controle, especially with more wind Close to each other = somewhat more relaxed
