Check out "high performance sailing" by frank bethwaite. Im tellin' ya. If you grew up racing sailboats the information is so good it's almost like cheating. He wind tunnel tested wing vs. tubular masts, tip turbulators like are found on airplane wings, turbulence inducing leading edges to develop l...

theres an interesting chapter in "High Performance Sailing" by Frank Bethwaite who was a friggin genius with weather and fluid dynamics. From their testing he found that there was a 30-some % drag reduction on foils when polished vs. just sanded. There was not much difference when compared over a la...

We've had this happen in sailboats particularly catamarans and the problem was that the trailing edge was too thick and water would cling to the trailing edge rather than being a clean release. There wo...
