I am widening my Nacra NA 5.8 to 11.5 feet.
I have already added a squaretop w/boom and a carbon sprit and F18 chute. Boat will be setup as a very fast and hectic singlehander. i'm 6'5" and 220, the width should make it manageable.
Here's the question.
I have two options:
A. Fabricate a new bow foil which is 3.5 feet wider than stock. Run the pole on top of it. i have fabricated a stainless "triangle" on which the cable for foil prebend rests atop, and the pole passes through.
B. epoxy a stainless sleeve onto the carbon pole. Place a 2x2 T6 beam between the beams on the center line. Then run a cable from the back beam to the end of the (lengthened) dolphin striker rod. then run cable from DS rod to stainless sleeve where forestay attaches. Then run anther cable from DS post through spreader under forestay to end of pole for pole prebend.
- i would replicate the system seen on the GC32 catamarans.
the boat wont be in big seas, and i want to keep the jib tack low enough to continue to use the NA jib, so i have no proble with the pole siting lower than would be normal, hence the elaborate setup. I think that if i go with option B, i wont need to drill holes in the front of the hull either, and can manage pole side movement with the existing forward tangs, since all upward force will be managed by the under-stay.
thoughts?
