LEE BOW EFFECT

Right, so seriously this will go round and round, here's my last sketch on the subject..

Sketch A) determines a stock windward leeward course with the outer boundaries of the lay lines all things being equal. Steady Wind No tide.

Sketch B) Along comes a tide from the Right which effectively we're all agreed moves the water playing field and goal posts to the left .  Indicated in Red is an approximate course two boats would sail, one going downtide the other going uptide, OK it's extreme and exaggerated  for illustration purposes, but it is what happens, I've seen it so often, lots and lots of times, by the time the boats (boards) who haven't clocked it have sailed left, by the time they come right they're having to bear away to get to the mark and the boats that went right, benefited by the tidal lee bow sail at best a short dogleg on their second tack by getting high enough to get the tide on their stern on the second tack.. now go tell that to your chums Perry et al. Have a word with one of your current Hero's Geoff Carveth, he's been about and taking a thrashing like a man when he once tried to step up to a mans version of competitive regatta sailing..
