I think Glen's system there is 8:1 i.e., 7:1 at the rear and the lead forward I think qualifies as another purchase. I also think he has a wire under the tramp to take the block loading.
I'd like to know how those straps/strops are attached to the boom. Probably epoxy. Definitely NOT drilled and riveted I'll bet. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />

I asked about this system and sheeting directly from the boom in and earlier post but got no satisfactory answers <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" /> but I think it would work. I can't see any more load on the boom doing it that way than there already is. I doubt I'd use the system now though because of the kite sheet and halyard presence on the trampoline. Too congested.

Don't you just love 'A's. I hope I get to own one before I die.
