Some good points Ted and having a consumption display is a nice tool to have. Not sure if you deal with much current where you are, but does it make sense to speed up some when traveling against a current? My thinking is that at 6.5 knts, a significant current is going to affect your speed over ground and lengthen your time so at some point it might pay to burn more fuel to get out of the current quicker?
Because of the huge fuel consumption difference between 6.5 knots (1.5 GPH) and 8 knots (3.7 GPH), the opposing current would need to be above 5 knots to make the higher speed more economical. A 3 knot tidal current usually has me waiting till it reverses. I have opposed a 4 knot tidal current going through a narrow bridge opening and can tell you it's a white knuckle experience. I'm retired and patient. At 3 knots, I go with the flow, not against it.
