The Bear was a dual steam-powered sailing ship built in 1874.
She was 198 feet in length, had a displacement of 1,700 tons, and had six-inch-thick
sides, which had a long life in cold and icy environments. Bear was
framed with English oak wood, had iron plating on her stern, and had wooden sheathing
covering to resist puncture and compression by ice flows.
Built in Scotland for sealing, Bear was operated out of Newfoundland
for ten years. She was then transferred to the United States Revenue Cutter
Service, for which she worked the Alaskan coastline and Bering Sea. Her duties
varied and were often dangerous, and included protection of sealers and whalers, providing
general police protection, and emergency operations. Bear retired in
1926, by which time the first true icebreakers had been developed.
