I agree that fuel consumption is related more to speed and hull design than to engine make. However, you state:

"I claim NT is below Hull's speed, one of the least expensive boats in its entire class. Example of my NT37 1 x 380hp cummins speed at 7.4kn 1,5 gal/hour 1250rmp, same LWL Albin 43 2 x 120hp FL 7,5kn 3,5 gal/hours the question NT is a good length - width ratio and Lynn Senour Hull design."

With 380 (Cummins) you are not limited to hull speed, so will spend some, or most, of your time going faster, making a bigger wave, and using more fuel then the 120 (FL) is capable of doing.
