Okay, since nobody is responding to this post, I have to ask a technical/engineering question: If you are sailing upwind and against a current, is it better to have deep daggerboards, or do deep daggerboards make you more of a victim to the current (more underwater stuff to pull you sideways)?

For instance, in the Hobie Wave, with its minimal lateral resistance, I felt as though I was at mercy of the current. And I thought that if I had more lateral resistance (deeper boards), I could have made better use of the wind and made more ground against the current.

I think this is a very interesting question. Anybody?
