Would you want to use rip rap or otherwise protect the shore line from wake damage?
He sure would! There is a pond near North Webster, Indiana where they sell water sport supplies via mail order. (Bart's Ski Shop.) They apparently did some high speed boating in the pond without rip rap and you can tell. Not sure if they rectified it yet, but last time I looked they tore the living hell out of the banks. Looks terrible!
