Ed Hartman started his maritime life with a row boat on summer vacations to Annapolis. After a "real life" as a lawyer he followed his maritime passion in 1980 to operate Chesapeake Marine Tours and Charters, Inc., which he had started with a single boat and a partner in 1972. Today, the company has a fleet of 11 boats ranging from 24-ft. water taxis to 65-ft. dinner cruisers. This June will see the addition of the fleet's twelfth boat and flag ship, 109 x 27-ft. 250 passenger Catherine Marie. Building at Freeport Shipbuilding in Florida, the boat is powered by a pair of Cummins C6TA M3 deliverning 350 hp @ 2,500 rpm and driving through Twin Disc MG5091 gears with a 2.95:1 ratio. The two 70 Kw gen sets on the new vessel are powered by Cummins 6BT 5.9 MG2 engines.
