Merry Christmas Sailors:
Many ideas and opinions have been written in this forum about consumption, cruising speed, engine RPM, etc.
I am yet to find out what is economical and what is not for a specific boat size and weight. When I project the behavior of my boat, which is one of a kind because it is the first one in its size and design and there’s no brother vessel to compare, the best I can get is 2.4 miles/gallon at 7 knots cruising speed. According to the same calculations max speed will be 8.5 knots where the performance would be at its best 1.45 miles/gallon.
Anyway, having in mind that the cruising speed of 7 knots, in a 55 Klbs displacement hull sliding in 40.2’ of LWL, are 2.39 miles/gallon an economical number or could the it be better?
For you guys with boats ranging the same size and weight, is this a good number?
Thank you for your answers.
