It's an interesting question as to whether this may be as bad in waves as intuition would have one think.
At first glance, "naturally" a pointy bow will slice through the water more easily.
But on second thought, if we compare equal beam (or thickness), which foil cuts through water better: one with a pointy leading edge, or a rounded one like this?
Actually the rounded one.
Of course, operating on the surface might change things.
Still, as ugly as this is, it has proven fast so far including in conditions that aren't anything like mirror smooth.
We may have prejudice against it because of high performance scows having so little freeboard as to be unable do well in waves, and we attribute their restriction to smooth condfitions to the roundness of the bow... but maybe that isn't the cause.
I hope this is not really faster, because it sure isn't pretty.
Another worthwhile question is that if not dealing with rating rules or concerned about per-foot mooring charges, would the boat be faster with the same amount of material
and same construction cost
put into a moderately longer boat with a finer bow?
Sure, one would probably gain only an extra couple of feet, but that might be enough to equal or more than equal the speed gain from the spoon bow.
(Of course we run into this consideration all the time with increased beam as well, but there seems usually to be little thought given to the fact that for same cost, more beam results in shorter length.)
