Hi Daniel

I tried it on my 18HT. We were not very happy with it and changed it back to the traditional 8:1 Lewmar system. One of the problems we had with it, was that sometimes after sheeting out allot and sheeting in again, one of the little blocks was canted. I also think the little blocks are to small, even with our tappered mainsheet (9mm to 6mm) I felt some considerable friction.

On my next boat, Eagle 18HT, I will try the 10:1 harken setup.
