I know it's been done, but you may want to rethink putting a spin on a H16.
I've seen a lot of European H16 with spins on them.......so it must be an exciting experience.......something in me is saying that it could be too much sail though when the wind really begins to pick up.
Try this link out to Beachcats........not sure if this is what you are looking for.......i think it said H16 spin kit on an H14.
