There is not much wind recently.
I have been considering alternative activity on the water and want to learn water ski, or wake board ( whichever is easier )
What is minimum requirement for outboard motor to be able to pull a water skier ?

I have 18 Hp Tohatsu and light inflatable boat ( or my catamaran which could go up to 30 km/h with this motor and 2-3 people on board). If that setup will be able to pull a skier ?
