Maybe I can add a little bit of an answer to the question. Now, as a pilot we do have a thing called best range airspeed. It is dependent on density altitude, weight etc. I am sure boats have about the same thing. Now here is the rub, it is only accurate in still air (water) so you add a bit (exact formulas vary) of airspeed for a head wind and subtract for a tail wind. Very general I know but now we can look in the correct direction.
