That doesn't sound right. I'm thinking your dodger must be too high. I wouldn't think you'd want to change the shape of the main to compensate. But I guess if I were you, I'd do what I had to, to make it work.
Is there any chance you to adjust your main so it sits higher on the mast? Is there room at the mast head to do that? Seems like that would be a good way to go, even if you had to alter it a bit. I'm sure you don't want to loss that dodger. That's something I'm hoping to add to my boat. I have very little room in which to do it, so it will have to be a small one.
