I was originally looking into a 1980 Glastron-Carlson CV27, everything on it is original, including the engines. So I know I can it get relatively cheap, but I'm cash poor, so I would have to loan out the project. That gets expensive when the interest rate is double that of a 15yr boat loan. But the boat is super cool and would look amazing if I could do what I wanted. Then I just scrapped the entire idea and decided on the Sonic. There are two currently in my price range. One with twin 454's the other a single 502. Then the issue of what can the boat do for the family came up hence the open bow "family" boat arose.
If I could pull an inner tube of something with the Sonic I would be ok, but I don't know if that's possible.
