Seeing the "Rare Centurions" thread title, I thought I'd add a bit about this boat my family has had since new in 1993. Unfortunately, the person who used to know all about the boat is no longer here. So after some exchanges with someone who is "In the know" so to speak, I found that it's a sort of prototype boat they build only a handful of. If correct, it was built as a boat for ski races (such as the Catalina Ski Race.)
Thinking about rigging it soon - it's never been in the water!
