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..
