i have purchased 2 f18 sails (mkI&mkII) for my 94 mystere 5.5. they both fit and performed extremely well (the difference from my boat to a f18 is i have a center board f18 have daggers)

I have had 2 tornado mains (both cut down a bit to better fit my mast). worked well


I am not sure what size your mast is, mine is 30'
