I fit into a lot of items being discussed on this thread. I have a 21 Prostar, ski on a public lake and am not a member of any club or association. I purchased my own ski course for our lake and have a great group of skiers that connect on the weekends when we are at the lake. I also have a surf boat (dont hate), as my kids were spending all their time with other families on their boats. IMO I did this to spend more time with my kids and can have them bring their friends. There are ways to use a surf boat to limit the annoyance to others on the lake and the beaches, but most of the owners of these barges are uneducated or just assholes. The next hated issue is seadoo's and jet ski's. We have 2 of each and my daughter and friends love these (I hate them). This keeps my teenage daughter coming to the lake and getting outside and enjoying the water rather than sitting inside on social media.
Sorry I went off topic on the ski boat issue, but my point is that regular casual skiers still purchase new ski boats (me) and that an educated person on the water makes the difference not just the watercraft (barge or seadoo) that they are using.
