Sabino
Only two members survive of the American mosquito fleet. One of the two, called Sabino, is housed at the Mystic Seaport Museum in Mystic, Connecticut. Additionally, Sabino is a National Historic Landmark.
The wooden, coal-fired steamboat was built in 1908 at the W. Irving Adams shipyard in East Boothbay, Maine. The boat has served the entirety of its career as a ferry vessel. Even in its preserved status, patrons of the Mystic Seaport Museum can take a ferry ride on Sabino. Being a passenger aboard Sabino is a wonderful childhood memory of mine, but I much prefer my efficient Johnson outboard motor (filled with Johnson outboard oil) nowadays.
