Here is the full skinny. The Game wardens are interpreting a swimmer rule to apply to wakesurfing. The law states that a boat cannot be under power, other than idle, within 50 feet of a swimmer.
The horrible and moronic interpretation is that once a surfer lets go of the rope, they are then a swimmer, and therefore the driver is breaking the swimmer / idle law.
I've been pulled 3 times now for it and oddly enough, they just won't give me a ticket. Even after debating the definition of the word swimmer to the extent the people in my boat are begging me to shut up and let it go.
My theory is they don't want to hand out a ticket because they don't want to defend it in court.
