I have an unrelated question about boats. Assuming a boat is sailing with its hull in the water (not up on the foils), would it be faster if the hull were flexible? My logic is that wind means bumpy water (I think these are called "waves") and vehicles on bumpy surfaces are faster with suspension.

ever see an iceboat ?
with low drag on ice they can go 100mph in 20 to 30 mph wind speed
lift is the force giving the speed
dead down wind is all drag no lift and slow
a whale can flex some but most are faster under water then at the surface
do to drag from surface waves the moving body produces aka wake
even rubber boats add hard bottoms to go fast as flex is drag
