OK, I 20 guys, how do you deal with the extra luff length on the spin? Should I be taking the mast back toll the spin luff is tighter? When I use the spin, the luff shakes way more than the spin on my N60, can't figure why, is it due to the slack luff?
The tuning guide on this forum has the mast standing pretty straight up, which would mean slack spin luff. Is that right?
Also, I have shortened the spin pole guys by about 2 " , pulling the tip down about 4.5". Without this the spin would go about 1' above the bail
I20 spin luff lengths have lengthened a bit over time (look at old Worrel photos and how straight the spinnaker poles were). You will need a LOT of prebend in the spinnaker pole to get the right luff tension with the stock rigging. It required so much on our last boat/spin, that I stopped putting the spin pole through the welded fitting in the forestay hardware and suspended it below with separate spliced mid-pole bridles (similar to how the old Nacra F18 was rigged) and made new end-pole bridles. There's no point in pre-loading the pole so the lightest down tweak will break the sucker.
