The blocks on your "bow foil" .... are they "Cheek Blocks"???? If they are they are for a Jib Luff Tensioning system. Is your "mast rotator" mounted at the mast base and in front of the mast, also is it "trapizodial" in shape??? If so that is the upgraded "Over-Rotatable" Mast rotation system. You over rotate the mast going downwind (w/o the spin) for improved downwind performance. You have to cross the lines ... port to starboard, starboard to port when attaching them.

"Md Blow Boater" has a thread several weeks ago where we discussed some of these issues .... I just forgot the name of the thread .....
