RE: Fuel Economy Question
I am looking at several different trawlers at the moment. The Marine Trader 34 typically has a 120 HP engine with a cruising speed of 6K. A 36' Morgan West Indian has a 160HP engine with a cruising speed of 8K. Being retarded when it comes to motors, I made some simple calculations:
This is advert garbage , useless for real world comparisons.
A real speed / fuelflow test of both would be required , not addvert blah blah.
Usually the displaced weight will determine the fuel use at every speed ,
however the speed desired will change the fuel burn by the greatest percentage , 300% extra to go fast.
Simply find the square root of the boats LWL , and that number in K is the cheap speed.
Hull speed? , that 200%-300% extra will apply.
