I believe the book you are referring to is "Design for Fast Sailing" by Bruce and Morse (Moorwood was the editor). This was a hard cover book produced by the...
As the result of many years of dinghy and keelboat racing in the Firth of Forth, I am satisfied that sailing in shallow water slows you down significantly and...
... There is definitely a bottom effect and it gets more pronounced with reducing width of water expanse (on rivers and canals). This is the Bernoulli effect...

And yet, speedsailing venues are not allowed to be less than some minimum depth, due to *advantageous* bottom effects. Surface waves are made smaller by...
... Would that be more due to planing effects with certain hull shapes that can take advantage of those when in shallower water? -- ...

I suspect that a planing hull may benefit in a similar way to a WIG (wing in ground effect) aerofoil, which may counterract the additional frictional drag in...
Hi I followed the link to the Bernoulli web page, but relating that to the close hauled performance of yachts in different depths of water is beyond my ...
Supporting what Paul says, there is a big difference between the hydrodynamics of keelboats sailing close-hauled (displacement-sailing at low Froude numbers in...
AIRWORTHYNESS OF POWER BOATS I have been thinking about this for many years - specifically since the flight of Donald Campbell's Bluebird. I am not sure how...
... The reason why the R/C airboats do so well is the fact that they have big, effective ailerons and elevators, sometimes on both the main hull and the...
This is very true! I have often thought about this myself. It seems amazing that these powerboaters never considered what would happen when their boats left...
