M_Boats: and just when y'all were . . .

. . . hoping you wouldn't hear from me again this weekend, I have another rudder question . . . Does rudder weight affect rudder performance, and if so, why? For instance, will an ultralight rudder allow more lift? I was thinking it would be good to add more weight to my kickup blade to help keep it down, but it seems I've read that performance rudders are very light. Or is it just that EVERYTHING on a performance boat is very light?
