OK, I have a dumb newbie question that I *think* I I maybe know the answer to, but I'm going to ask anyway.
First, the background: On our last sail, it was beautiful on the way out, with wind from the SSW at maybe 6 knots. We had a leisurely sail to the other side of lake -- tacked a few times without issue, and we moving along at between 4-5 knots. About 3/4 of the way there, the wind started picking up, and we turned around to head back. Judging by the many, many whitecaps, the wind was probably up to 12 or 13 knots about 10 minutes later, and the marina we needed to get back to was due south. I don't think the direction of the wind had changed much. If anything, maybe it changed to be slightly more SW.
Now, here's where my terminology fails me, so please bear with me. When we tried to point SE, we beat the hell out of the boat and had the top rail a little closer to the water than I would generally like to see it, being a big chicken and all. When we pointed the boat a little more due South, it successfully slowed us down a bit, but the mainsail had a very weird shape to it. Like it was an "S" -- and it was flapping pretty good. We were able to keep it there and make pretty decent speed (about 4 knots) considering the pounding (and man did it pound. I think we need some sandbags in the forward hatch) but the sail flapped the whole way, no matter what we did to the jib. The only way we could get it to stop slapping against the standing rigging was to go way faster than we were comfortable going, heeled over way more than we were comfortable heeling.
I did try to research it a bit using google, but most of what I read dealt with larger boats and it sounded like sailing windward in rough water isn't fun no matter what size boat you have. I guess my question is, is the Weekender particularly bad at sailing windward? I mean, it was fun and all, but since we're still learning what the boat "feels like," I figured I'd run it by you all. Thanks, as always for your collective experience!
