May have found a fix for this, but would like a little more info. I have the Tambor taking 8-10 minutes by the game clock to go from 5 knots to 0 knots with no reverse bell applied. Will be putting the file out to the RFB testers to make sure the change doesn't screw something else up.

Any one got an idea what would be accurate? Any diesel boat sailors that can throw some numbers at me?
What would be accurate would be 2000 tons of steel ploughing through the water at 5 knots. If you just ring up all stop, you are just putting the engines in neutral - you have not turned off the Kinetic Energy of the boat. I would figure that it would take at least one mile to 'coast' to a complete stop.

If you need to stop faster than that, I would suggest you ring up 'All Back'. The faster you need to stop, the faster you will need to reverse. When the Speed-O-Meter reaches '0', THEN hit All Stop.

Newton's 'First Law of the Conservation of Energy' states: "A body in motion tends to stay in motion in a straight line until acted upon by an external force" (like friction or gravity). There are formulae to express this phenonoma, but one of our wiser folks on the forum will have to give it to you.
