Re: Question about spreader/rigging geometry
I think the answer to your question is that it is easier and stronger to attach the spreader to the mast at a perpendicular than at a slightly upward angle, and that given that the only part of the spreader that is permanently anchored is that connection, people have chosen to do that. It is not dissimilar to the joinery that takes place in building furniture. Theoretically, if the attachment is overengineered as RichH has suggested, then it is irrelevant the angle they take. Agree that the physics works better when they bisect the angle of the shroud, but that force may be negligible, and when the shrouds "relax" on an opposite tack, if the spreaders were upswept properly, but not significantly anchored to the mast strongly enough and more permanently, they could slide down as it seems yours may have. Anyone stand on them and compromise that joint?
Historically, lashing on a spreader at a right angle to the mast was essentially the only way to do it, so some of it may also be design aesthetic harkening back to that.
Oh yeah- and if you don't like wire clamps, you could do a lashing at the spreader tips, which should allow better access to oxygen to keep those stainless shrouds from pitting/rusting.
