Havent really noticed a major diffrence. i think it may be a little too fat but better same than sorry. I do thing i am over weight.. well not just me, but the boat. I have ran the same distance with my partner V/S solo on the same day, same conditions with a 3 MPH increase. I think if I took out some weight and had my prop B&B I could hit the high 70's. AS of right now with 2 people fully loaded with a full tank i am running 73 @ 6K. 75 Solo
