I have the sail, the hound is barkin and the pole is ready to go......On the H20, how and "exactly" where do you attach the main blocks, or, where is the sheeting point?
I've been told to attach them to the aft beam....

Hi Eric

It depends on your spin measurements and area ,
most particularly the spin foot -

If its a 270 sq ft spin with similar length pole
then the proper location may be more forward around the side staye like the I-20s have in spin set up .

Think this is more as the spin is designed and also helps performance and handling characteristics .

Hope that helps
