bigwhoop....see my posting on Jan 04, 2011 above. my factory shroud wires have a breaking strength of around 3,000# so it's overkill fer shur. factory CYA? if working strength is 50% (just a guess) then any block i would add into the system sized to match that loading would be huge......(as big as my head perhaps?)

will look into the sail since experience sez it's worth it. thanks!!

since i first posted the question on this forum concerning the loads that a shroud must handle, i've been thinking (obviously......very slooowwly). this summer, i was out on my 5.8 with my crew, who weighs about 220 and he was out on the wire when we were flying a hull. he looked up at the windward shroud (the one that should have been holding up the mast and it was slack. he was actually supporting the mast with the trap wire that he was suspended from.

now granted, it wasn't blowing anywhere near 20 but it was enough to have him on the wire and flying a hull. so the question is, are the loads that great that a trap wire alone can support the mast?
