(1) Mast rake adjustment – Detach crew trapeze from bungy and add a 3' piece of line to it. Holding mast
straight and pulling the trapeze line tight, measure to top of bridle pin on bow. Mark the line and take to rear of
boat. Rudder should be up and locked. Mark on line should touch trailing edge of rudder (facing up since
rudder is up) approximately 6" from tip of rudder.
(2) This tension pre-bends the mast and flattens the sail, vary the setting for the fullness or flatness of your sail.
Spreader Rake = 1" to 2" from the back of the mast to a line between the aft edges of the spreaders
(3) To get this kind of mast rotation requires a loose rig and a positive mast rotation system.
