I have a 1960 Biesemeyer ski boat, and I have only seen 1 other boat like it. I am considering selling it to buy something bigger. Does anyone have any idea what something like this goes for? The carpet needs to be replaced but other than that it is in pretty good condition. It has a 1964 mercury kekiefer 100hp. outboard. Thanks for your help!

Help me out. Any ideas??

You need to find the right buyer. To most it is just an old boat. Check Ebay and craigslist for similar as a starting point. You will probably be disappointed in what they are going for. Put a listing in craigslist and see if you get a bite. Good luck.
By the way, I have never sold a boat, I only know people who have. I only seem to buy them.
