Hi Bill, this pic is the best I could find on the downhaul fixing method that most of us use (we are allowed to do anything with most of our rigging, I think the Mosquito is probably one of the most open one-design boats around - the rule on rudders allow you to build or buy any rudders of any shape or length that you think will work. Generally it isn`t the rudders that win the race. In fact these open-minded class rules disprove many of the popular myths in sailing, our boats are all set up differently to a certain extent, yet the fast guys always win, and the lightest boat isn`t always the fastest (and it`s mine ) Even our hull shapes differ from one another within the building tolerances to a small degree. Of course all the epoxy boats are the same, but the woodies differ a bit.
We attach the bottom triple-block of the downhaul directly to the gooseneck with a shackle, simple and easy. My Gooseneck fitting is a little bent after 5 years of use, and the loads on our boats are quite small as you can see 5:1 or 6:1 downhaul is good enough.
These pics are both of Kevin`s boats, our National champ. the black & white boat is an epoxy, his 2nd boat, and he has streamlined all his systems to the minimum. His first boat had so much string on it the crew took up knitting.
Sorry no pic of mast rotator as he hadn`t fitted it when pics were taken. We connect to boom and seldom adjust unless the wind is very inconsistent, and I seldom let it off downwind with the kite up.
