I realize this thread is about the demise of DD boats, not about slamming wake boats, but I had to respond to @Shell 's comments, since he described just about everything about our lake. It is a small (150 acre) quasi private lake. I say quasi private because it is in a neighborhood, inside a gate, limited access to the outside world, unlimited access to the 500 or 1000 residents, whatever it is. About 10 years ago surfing and wake boats were banned. Lake was too small for them. I was and am fully on board with the decision. The language was sloppy and had holes in it, but it has since been tuned up. No ballast (can be used) does not say no boats with ballast capacity), no wake enhancing devices (wedges, NSS.....) ropes must be longer than 30 feet and you must use a rope (I actually got an exemption for those for my BF boom since people whined about that based on the language) and finally, "no surfing" So we pretty much have the problem licked here (also, jet skis are not allowed, so its a win win) Meanwhile, in a sister neighborhood across the highway, with an 800 acre lake (or 1200 acre, not sure) They took no such action 10 years ago. Now they have a bunch of problems with surf boats, giant wakes, shoreline, bulkhead, tied up boats....you know the drill, and they are stuck. Cant take away an existing right. Cant say, you cant use your boat any more. They are grasping at the only straw they have and that is to grandfather existing but allow no more. But the existing is too much and too many, so they are pretty much screwed. Its one thing to say you have to stay 200, 400, 500 whatever feet from shore on a huge lake, but on lakes this size, it either yes or no. Fortunately for us, its a no.
As far as the original topic, who knows the fate of DD boats. Grow the market, down to 2 or 1 manufacturers, a decent $40,000 ski boat that can be tricked up to pro level options? A world full of well preserved used boats? Hard to say.
