Rental shmental. I have everything one needs to wakeboard. We go out in salt water Turtle Cove, right across the bay from Long Beach Island. Sadly, the New Jerey wakeboarding season is just about over. Weather permitting we're going to go out this weekend and that may be it for the year. It's time to start prepping the boat for the long Winter hibernation. If you ever want to take the long ride to Long Beach Island, just let me know.
