Ok so on a typical 30 boat theoretical hull speed is app 7.5 knots on a displacement hull the power needed to push the vessel faster than that is extremely Inefficient which would cost heavily in fuel cost, we operate planning hulls which are design to have the ability to be able to climb onto it's bow wave, now the correlation between the bow and stern wave is still the same that hasn't changed enabling the vessel to greatly exceed hull speed " which is not a limiting speed" However gasoline engines are inherently more efficient at higher rpm then lower, unlike a diesel engine so by trimming the boat to level it and reduce friction along the water, it may at times be more economical to operate at higher speeds. I'm sure there are many factors that come into play here also. On new boat tests many are more economical in the area of 3000 - 3500. Granted travel at hull speed is more efficient than adding a few knots and plowing trough the water but without accurately calculating fuel consumption to distance traveled it is a tough call .......installing flo scans on my 32 this winter so I will be back next spring with results.
