76[bolger] Re: Idaho?
- Aug 3, 1999I'm certainly no expert, but I would guess wetted surface area is far more
influential than finish, if finish is within reason. We are talking
turbulent flow here - when I raced (much slower) sailboats, we were careful
about the bottom finish and it made maybe 1/8 - 1/4 knot difference - quite
a bit at 3-4 knots over 10 -12 miles, but not much if you are already going
15-16 knots (and not racing).
