The tug Trio Bravo was originally built in 1898 by the Columbia Iron Works and Drydock in Baltimore as the Cumberland.  She was 142 feet in length and 27 feet in breadth.  Initially owned by the Consolidated Coal Company of Boston, she was sold to the Army Corps of Engineers and assigned to the Milwaukee district.

In 1947 she was sold to C.F. Temby of Kewaunee, Wisconsin.  She was again sold in 1951 to the Roen Steamship Company of Milwaukee, and renamed the John Roen V.  In 1973, the tug operated for Eder Barge & Towing, until her sale in 1980 to the Trio Shipping Group, whereupon she was renamed the Trio Bravo.  The aged workboat eventually sunk at her dock in Port Everglades in January 1981, and was eventually raised almost two months later.  She was eventually sunk in December 1982, and now rests in 150 feet of water just north of Port Everglades.  Resting to port, the wreck demonstrates extensive damage from the excessive scuttling charge that sent her to the bottom.
