A pair of conspicuously large masts outside Front Street Shipyard's Building 5 on June 27 were found to belong to a 100-foot sailing ship inside. The steel-hulled Corwith Cramer has been in Belfast for three weeks getting its first major overhaul, which a crew member said would take about three months.

The 30-year-old, 240-ton brigantine is one of two sailing school vessels operated by Sea Education Association (SEA). Corwith Cramer sails in the North Atlantic and the Caribbean Sea. Its counterpart, Robert C. Seamans, sails throughout the Pacific Ocean.

The masts of Corwith Cramer, like the hull, are steel, and rugged enough to stand out among the sleek lines of several racing yachts in the shipyard lot on June 27.

Crew members were undressing the foremast. One of them, a yard worker named Laura Rea, said this involves taking off cables and stays. As some of this hasn't happened before, it wasn't necessarily easy.

"A lot of hitting out rusted pins," she said.

Rea grew up in Idaho and got involved with SEA as an undergraduate after spotting the program among several study abroad options. "I thought it sounded cool, so it did it," she said. When she graduated, she signed on as a deckhand and yard worker and now does social media for the ship.

Most of the crew is boarding at the former Crosby High School, Rea said.

The school has dormitory-style rooms on the upper floors that the new owner, Kiril Lozanov, has expressed interest in converting to a combination of shared housing and a hostel for short-term visitors traveling light.

Across the yard from where Corwith Cramer's crew was working Tuesday, a crowd gathered to watch as Cangarda, a 1901 steam-powered yacht, was lowered into the harbor by Front Street Shipyard's 485-ton travel lift.
