Myles, I like that.
FWIW, here are the numbers for my Albin 25:
kwh/nm speed(kt)
.767 6
.392 5
.245 4
.163 3
Or, taking the inverse:
nm/kwh speed(kt)
1.3 6
2.6 5
4.1 4
6.1 3
Displacement is similar to yours, but I'm guessing she has a "slipperier" bottom shape.
Someone said we need a standard of comparison. Maybe this could be a helpful part of that, especially since we're all used to thinking in terms of MPG for our cars. Waddya think?
