    it should take a fair amount of weight to effect the speeds at 70lbs lighter he should be a little faster.

    Thats what we thought at first....we figured the extra weight on the rear lifted the nose out of the water more. I got a kid that weighs 125 lbs to ride my ski so that I could get that magic gps number, nope, speed within 1/2 mph of my heavy self...

    In the group that I ride with we've found that weight does not effect speed, or at least much. We vary from 180 to 300 and rarely is on faster then the other on the same boat when it comes to top speed. All of our boats range from upper 70s to low 80s. Acceleration is a different story.

    I think speed is more about the amount of lift you can get on the nose of the boat, more than the weight of the rider. I have 50 lbs and about 4 inches of height on my buddy and I am about 1 mph faster than him on my old ski. See pictures below.

    I agree with Kirk. If your getting the weight towards the back, being heavier actually helps on top speed.

    When my 97 was stock, I raced another 97 and I had a passenger on the back and he did not. The passenger squated down on the rear deck and held on to the grab handle and I basically put my ass in his face & we walked away from the other 97.

    Warning: Do not try this, when you let off the throttle & the nose drops down you and the passenger will get ejected. This happened two times in a row and I will not try it again.
