You would need to know the amount of drag on each hull at various speeds, and how that drag was affected by weight.
That would determine the amount of force necessary to get a particular hull going a certain speed.
Another side of testing would be a dyno for our motors, where you could test a motor / esc at a given constant speed, to get a handle on the relationship between current and torque.
Props would introduce a another round of testing.
That way, you could figure out the most efficient way to generate the required amount of force.
This is just mt scientist / engineering brain trying to take a problem apart into smaller, more manageable chunks.
I'm SURE its not the only way.
Aside, This is why the science and engineering of racing is really expensive.
