5.5 meters is actually a little over 18 feet. 5.2 meters is in the 17 feet range. I looked up some pictures of Nacra 5.2s and I don't think it's one of those. It has the big square bows of the Nacra/Inter 17. That's how I knew it was a Nacra by only seeing the front half of it for a second or two as I drove by in the van.

Anyhow- assuming it is a Nacra/Inter 17, what would it be worth? If it's not that boat, I'm probably not interested.
