Thanks Budc , that basically what i was looking for as to ( what might be the difference ) Didnt want to find out the wrong answer when it might be to late, I didnt want to be spending twice the amount on gas for doing the same thing.I would like to have the extra room on the bigger boat,still a little worried about making the jump from 17 ft to 21 since i would be towing the boat about 170 miles one way when i go fishing, but then again i am only traveling that far about 5 times a year.
