I didn't realize on that last thread that you were comparing a NEW 210. I some how missed that. I actually have no experience with that boat.
I think it's going to be different for everyone. Altitude, ballast, number of passengers, riding speed, everything will vary.
Even if one boat burns one more gallon than the other per set, would that really sway your decision? When you're spending that much dough for a boat, is $20 extra at the end of the day going to matter?
Maybe this type of thinking is why I have no money.
