Stupid and just showing off!! When we lived in Ga. we fished Lanier a lot!!, a big lake with a lot of big boats that make big wakes, with stupid show offs at the helm. ( by the way , you are responsible for your wake around stationary objects and near by boats or property), That said, my bass boat--on slick water would run 80+. Early morning was great but mid day I always backed her down to about 60% power because of the waves. That little tip does a couple things for you--1-your not on the ragged edge--2--you have a ton of throttle response to get you out off trouble. Oh yea, jumping a wake is just plain stupid. If your faster than the boat in front you that you are approaching-- go over the wake at a shallow angle and throttle up as you go over. I'm rambling, boat safety is huge in my book. Water is a non-compressible so you only displace it---your riding on concrete.
