Any reason why you wouldn't want to just "ban" wake surfing as an activity on your lake?
We live on a stretch of river that prohibits the use of wake assisting devices (fat sacs/loading/hydroplate/etc) - that helped a few years ago, but unfortunately doesn't restrict the new generation of boats designed for surfing (which are causing the most damage to docks/banks)
Seems like by eliminating the activity (surfing), you might be able to reduce the number of boats producing that type of wake
