Skiing in the River

I was on a boat traveling in a river.  There was going to be a race of water skiers.  We started downstream and I swerved around the boat to pick up speed and then let go of the tow rope so I could go faster.  I was moving quite fast and my skis were narrow like snow skis.  I was moving my feet back and forth similar to the down hill slalom skiing.  there was one or two skiers ahead of me but I was gaining on them.  They were being towed by boats as opposed to me who was moving under my own power.
