Here is an excellent video showing one of USA's finest rednecks wake jumping.
I was wakeboarding behind my Nautique that threw a really nice BIG wake, and had a PWC spot the wake for jumping, come tearing from the starboard side across the lake and head for the wake about 40 feet behind the boat, which was 35 feet in front of me. Had I not thrown the handle/rope into the air, it would have ripped her and her kid right off the PWC. Her husband on shore immediately started yelling at her, and drove out in his boat to us to apologize profusely, saying she had never ridden a PWC before. Point being, be VERY aware of your surroundings.
Surfing a boat is fun too, but you had better be comfortable with big wave action.
