Shape and Flow: The Fluid Dynamics of Drag by Ascher H. Shapiro
Naval Architecture of Planing Hulls by Dr. Lindsay Lord
Hydrodynamica by Daniel Bernoulli
That’s one of the books my sister checked out for me at her high school when I was 10.
…just printed those out… they’ll be my before bed reading material this evening…
http://en.wikipedia.org/wiki/Planing_(sailing) too. There’s a lot here to think about. The fundamental is that wetted area decreases as you get up to plane, and the back part of the hull becomes a much smaller control surface. I noticed a while back that better surfers (on better waves) keep their front foot out ahead of the bow wake of their board and this is why Greg Griffin preaches “get off your front foot.” On front-footed boards like a lot of fish, you see a real push toward smaller boards to reduce wetted area (and shorten the rail). This and the lift entry together give me a better understanding of concave and outline and how good surfers and shapers can use it to go faster. The Coanda effect gives a rail or a hull suction. I look at hulls now and understand why the rails are bladed out.
Thanks!
