To check the most efficient speed, set the speed and then ask the nav officer the maximum distance for that speed; then go up and down in speed and repeat the question. You will soon know the maximum speed for maximum distance.

THX Irish....I should have added that part too!
......Also remember the the "most efficient" speed does NOT always stay the same.
It is affected by the weather / sea state.
What, in 0 mps winds, could have been Standard speed as most efficient, could change to 1/2 rd Speed during "heavy weather" with 15 mps winds.
It really does pay to keep talking to your crew!! That's what they are there for!
