Ernest, what engines are you running to turn 18x18's? I have 340 H.P. gas engines on a 31' S.F. which I have a light cup and are perfect for a 27 M.P.H. cruise and a 38 M.P.H. top end @ about a mile to the gallon (slightly less loaded). They are 3 blade, I checked into 4 blade but without more power I can't turn them. I don't know the preformance difference between the hulls, but the weights are close to the same. I have standard brass and would like nibral, but am happy with the preformance I have and don't know what they would add, except cost.
Scott D.
