I just had to make an edit...I missed a receipt for gas. Looks like my mileage did suffer a bit. More like 0.64mpg vs 0.71 I last calculated (with no dinghy).
I cruise between 22-23kts. With a following wind/sea yesterday it was closer to 24kts. 3,600rpm...
nice, that's fast. I can't run 23kt fully loaded comfortably for very long as its on the high end of rated cruise, we're more like 20kt and occasionally less than that.
I know we've all beat it to death but I think the diesel/gas mpg is closer that it seems if we consider running at the same speed. Any idea what your mpg is if you back down to ~20kt?
