There is no law for hull speed.



Theoretical hull speed is a precise measurement and generally close to
the mark. Joe already said his boat does 9 knots on 30 knots of air. So
how is his hull speed 13 knots? Does it hit 13 knots in 80 knots of
air?

Hull speed for a Hobie that isn't planing?

What is the theoretical speed? How did you derive it?

Note you are talking theories, not laws.

Glory!
