49mph wot with 80 gal and 3 people is impressive. That is what mine does wot on a good day with a light load. Seacrafts and yellowfins are within 250# or so and similar in design. I see a step or two on the yellowfin which might help at the top end a bit but pretty close.
I don't have a problem with the 140 weight...they weigh the same as the rudes...exactly. (although rude makes a 175 also at that weight)
