Hello,
This has probably been flogged to death but I am going to ask anyway.
What is the formula for calculating boat speed?
From memory the propeller pitch, engine rpm a reduction for slippage and a
couple of other things are needed.
I did have the formula on the computer but a recent crash of the system
caused it to be "misplaced"
Many thanks..
