The tugboat, Charlotte, built circa 1880 as a sandbagger sailboat. Later, she was converted to power between 1915 and 1920. Her original power was a one cylinder Wolverine gas engine. She was used by Steers Sand and Gravel Corporation of Northport, Long Island, New York as a launch and a barge by the workers at the Sand City work-site, now called Hobart Beach.

She was purchased in 1923 by Captain Dexter Seymour, who renamed her after his daughter and planned to use her as a work boat in his newly opened boat repair yard, Seymour Boat Shop, Inc. Charlotte was repowered many times over the years: in 1936 with a four cylinder Palmer gas engine; in 1945 with a four cylinder Lathrop gas engine; in 1966 with a six cylinder Palmer and finally in 1981 with a Ford Lehman 135 horse-power diesel engine.

In January, 1980 Charles J. Quinn acquired Charlotte with the purchase of the Seymour estate. Charlotte was donated to the Long Island Maritime Museum, formerly the Suffolk Marine Museum, in 1984. She has performed many duties for the Museum over the last twenty years. Primarily, she has been used for various projects in the Museum's boat basin and participated as a committee boat for many Museum regattas.

She will undergo a restoration sometime in the near future. Her restoration will be comprehensive and include some work on her hull as well as a complete rebuild of her deck and topsides.
