[quote=dmgbear55]Yes, in fact I have owned the boat since 1976 then last summer I decided to do a complete rebuild. Now the boat is better than new, until I go out and mess it up.
The diamond wires control flatness by allowing/controlling the bending when the mast is rotated. The downhaul can flatten the main without rotation. So it is possible to get a cleaner airfoil. I forget what Andrew suggested for the downhaul, but likely it was in the 6:1 ratio, much more than was on the original setup.[/quote]
