Kevin,

Attached is a photo of my 16:1 setup on my Nacra 5.5. It is cascading 8:1/2:1 or something like that.

The photo cuts off the top of the setup. What is missing is the hooks that go through the gromet in the sail. By keeping the original hooks I can keep the whole setup rigged on the boat all the time.

It is hard to see but there are 3 blocks at the bottom besides the exit blocks/cleats. One on each side plus one centered on the track. I put a small aluminum plate just inside the track to bolt that block to.

I have more photos, and at higher resolution. If anyone wants them let me know and I will e-mail them.
