G'day Rolf the spin was designed for a Nacra 5.8, it's in good condition and came with the boat. The helm is okay but I cant get this spin to get going like my Taipan 5.7 used to go, that must have been set just right because I just got on it and went. I don't adjust the mast rake for spin should I?. It is easy to lift the hoist as its just a rope bail that goes into holes in the mast track so I will just drill some small holes for a higher hoist, the actual top support for the hoist is a saddle about 3ft above with a rope to the top block. The hard bit is how high to take the hoist, I'm thinking of taking it 10 inches up. This spin does have a lot of draft as all the Aus 5.8 spins apparently did but my current setup isn't helping, I'm currently considering putting a flatter F18 kite on it. Thanks for the info Scarecrow I've got 2 days of sailing this weekend so I can have a real play with the setup
