so what happens if this proposed hull shape is actually faster by a small, but noticable margin? Everyone runs out to buy the new boat? Is that what they refer to in other threads about "arms race"?
This could be a good thing. If the difference is small enough, it only matters to the best, most competitive sailors. Then they'll run out and buy a new boat and sell their older but still great boat to a less competitive sailor at a discount.
It's the trickle-down theory of class building.
