from that article
"The Boston Herald reported in 1996 on Kerry’s "a 200-horsepower SeaCraft powerboat valued at $20,000."
It actually had twin 200HP motors and quite a questionable history........
I do not think they have it any more but they do have a 27 Contender with twin 200+ engines. I have seen him a few times in Vineyard Sounds full tilt to the islands, he is not afraid to run the boat a full throttle.
