Wakesurfer
Wakesurfing is a variant of wakeboarding where you are pulled by a boat first. Thus, an adrenaline rush is also quite sure with this sport. However, here you have a clearer feeling of freedom than in wakeboarding. It's about actually surfing on the wake behind the boat, so you let go of the rope after a while and are completely free in your movements. Your attention is only on yourself, your board and the water.
