What are we looking at?

I actually saw this boat this summer, as it drove by me while I was working on my boat in Woods Hole. As soon as I saw it I ran to try and catch the person in hopes of talking to him, but alas I was too slow.

It is definately an inboard seacraft (it has the hull vents/curved transom/ integral bow rail) and I know where it is kept. I had planned on doing a recon mission on it this summer however, I just couldn't get a chance to do it.
