I saw a TV show filmed at North Sails showing how they make one of those A
Cup mainsails. They form a solid plug of wood, or similar, then lay laser
pre-cut pieces of kevlar, etc on the plug and sew it together with a giant
moving sewing needle on a CNC controlled machine in 3D.
The amazing thing

Hit the delete key if your not interested, sorry, but I find this
fascinating. Boy, during the winter, you guys will go on about anything.
;-) Honestly, I think there are a lot of applicable principles here, and
I am amazed at the number of RC soaring guys who are/have been sailors.

OK, here we go. There is true wind and there is apparent wind. Apparent wind is the
wind you feel if there is no wind and you're
on a bike and you start moving forward. It feels like there is wind, right?
Sailboats use wind and forward motion to work. Proper
sail trim is extremely important

Just think of ground wind speed the level sailvehicle is the thermal rise

While 120mph is extreme speed for any sailcraft, it would not require winds
of 120mph
Hi Guys,
Anybody been paying any attention to the "Luis Vuitton Cup?" Notice the
shape of the mainsails. Can you say elliptical? They seem to be running
fairly high aspect ratio with really close to elliptically shaped
sails.(Or should I call them wings?) I'm not a sailor (but I'd like to
