We have just started wakeboarding. We have a 2004 Mobius LSV with stock ballast (single sack in ski locker). I have noticed that it seems difficult to get a nice balanced wake on both sides of the the boat. The wake on the right side of the boat seems to consistently be nicely shaped, but the wake on the left side, especially at speeds in the 15-18 mph range seems to be washed out. Filling the ballast did not seem to make much difference in the wake shape except the wake was taller. The one thing that seemed to make a difference was when my wife and youngest son sat opposite the drivers seat on the left side. Normally, my wife alone sits there and the riding son sits on the left side of the boat in the back. With son & wife opposite the drivers seat, both wakes seemed pretty well shaped, especially pulling my older son in the 19-20 mph range. Does anyone have any hints, tips, clues on what you should look at when one wake or the other seems washed out? Thanks for any help.
