The curvy daggarboards are too hard for my pea-brain to comprehend, so I'll stick with the simple canted-daggar style.

Am I correct in presuming that a canted daggarboard is more effective going downhill than uphill?

Would the vertical (zero cant) orientation be better upwind to counter the leeway? Or would there be some benefit of vertical lift (i.e., lifting the hull out of the water) with the heeled boat going upwind?

If this is true, is there a good "average" degree of cant that works for beachcats with spins (typically heeled about 15-20 degrees already)?
