Critter: Steve A has it right on both points (the stay sail) and especially his heading "no such thing as a dumb question" but there are a lot of dumb answers and I try to be very careful with my answers. Part of my problem, when I got back into sailing many years ago, was trying to figure out the correct question to ask because "a man does not know what he doesn't know". The answers I would get, with hindsight, were unbelievable but I did not know any better - until I went out sailing and tried them on my boat and I found that most didn't work. To illustrate, try this with your sailing friends. Ask them to describe draft depth and draft position and then ask them what controls are used to adjust each element (review my articles on both items before you ask the question). You probably won't get past the first section of the question and they'll be describing twist plus everything else you could imagine or ask them to explain the function of the traveler and the outhaul. Every sailor and I mean EVERY sailor goes through the same learning sequence and the questions they ask are the same - they just ask them differently. I talk to sailors all over the world about sail trim in conjunction with my sail trim book and chart and I think I have heard every question about sail trim that anyone could think of. Sooo, just fire away. On a lot of the questions, I think to myself, I should have thought of that question!!
