Found on a Chris Craft site:

More vintage glass (our 1966 17' Century Fibersport inboard)
December 26 2007, by Tom Slayton

When I was a kid, we had a new 1966 Century Fibersport, which was the first fiberglass boat produced by Century. When Century saw all the boats Chris Craft was selling, it didn't take long for them to follow suit. The boat looked just like the Resorter and it had a Ford 352 Interceptor with 250-hp, and that dog would run!

Here is a photo of one I found the other day, just wondering if there were any left. This one is restored to show quality, and was for sale at $20,000. I was surprised to find several of these on the marketplace, ranging from $8500 and up.
