Boat Speed

How fast is your boat? Do you know? Does the question even make sense? Isn't any boat going to go faster if you apply more power to making it move? What people really should ask is" "how efficient is your boat?"

What efficiency means is that for a certain amount of energy applied to making the boat move, you will get a certain amount of motion. A more efficient boat will move more with less effort. This could mean that for a given speed a more efficient boat will require less effort, or for a given effort, a more efficient boat will move faster.
