So is a leech (leach, letch, leche, spelling optional) line a sail-based alternative to a vang/mainsheet, and therefore most useful on downwind points of sail when it's otherwise hard to sufficiently tension the leech? Or does it rather alter the harmonic of the fabric edge, which may not respond even to hard vanging and downward sheeting cuz it's stretched out?
It's clear that kind of vibration could hammer the fibers and resins on a sail; laminates must be really prone to leech fatigue, no? Are the gains worthwhile on smaller, high aspect sails like blade jibs and the tall narrow main of the San Juan 21? (23' luff; 8.5' foot)
Heh. Sometimes I think sailors are kittens and just enjoy having another string to pull. & then realize how bloody incomplete my youthful sailing education was. Never saw a leech line back then. Never saw a traveler. Never saw a jib car, even on quite large boats. No one jibed, not on purpose -- it was considered terrible form. One comes about, thru the wind properly, dontcherknow, or one doesn't sail at'tall. These my teachers talked about sailing a lot, they smoked pipes and waved them about convincingly, they even raced one another about the lakes in a genteel, old-money sort of way.
But I'm starting to suspect they weren't very good sailors. I've learned more from you lot in six months than in eight years before the mast in New York. Sheesh. Where the hell were you in ... say ... 1980?
