twist, acceleration and speed
I am a couple seasons into learning to sail the Scot (and a Catalina). I have read a great deal, but I still do not understand more precisely what I think authors are saying. My guess is that I am misunderstanding so I would like your help.
For pointing, it seems that the mainsail top batten chord should be parallel to the centerline boom position, or even turning a bit windward by a few degrees. However, doesn't that then cause the upper sail to not twist with the upward twist in the apparent wind direction, given the apparent wind at the top is greater in speed and therefore angled a bit more to the side of the boat? Why would we want to lose that ability of the upper sail to drive the boat? Why not twist it to match the twist of the wind to maximize the speed while pointing in the same direction? I do not understand how you gain from that. One author I read also said that you never sacrifice speed for pointing, but even he recommends sailing with the upper batten chord parallel to centerline (vs angled out 5-10 degrees). I also do not understand what authors mean when they say that you can increase acceleration by easing the main but you won't increase speed windward. I don't get it. If you accelerate you have to be going faster!! Any advice from the Scot peanut gallery here would be greatly appreciated!!! Frank
