- 4.5 to 5 knots on one engine = 2.75 to 3 nmpg (occasionally utilized in thin canal areas where docks / anchored / moored / small fishing boats abound)

- 6.5 to 7 knots on twins = 1.75 to 2 nmpg (often used in SF Delta - calced hull speed is 7.58 knots)

- 16 to 17 knots on full plane = 1 nmpg (whenever in relatively open water needing/wanting to get some distance covered)

- 21 to 22 knots at WOT = Way Too Much Fuel (used for short bursts when needed)
