The boat is described as "stunt double for the boat in Jaws." Harry Dresden describes it as an ancient, battered commercial fishing boat. Thomas Raith once told him it was a trawler. It's forty-two feet long, and desperately needs some paint—its white hull had faded to grey and smoke-smudged black. The only fresh paint was the lettering for its name: Water Beetle. It had originally been built for charter use on the open sea, so it had some muscle. The Water Beetle has a secret compartment large enough to hide several women and their children. Thomas keeps it at Burnham Harbor.
