The Sabino steamboat was built in 1908 in East Boothbay, Maine, by W. Irving Adams, she spent most of her career ferrying passengers and cargo between Maine towns and islands. First she operated on the Damariscotta River in midcoast Maine. After sinking during an accident in 1918, she ran on the Kennebec River. From 1927 to 1960 she served the islands of Casco Bay, running out of Portland. For this service her narrow hull was widened with sponsons to make her more stable in the open waters. Although her configuration and passenger capacity changed through the years, her engine did not. The Sabino Steamboat still has the two-cylinder Paine compound steam engine that was installed in 1908.
