Blount Boats Inc., Warren, R.I., delivered the steel-hulled 94'×27'×10' buoy tender/icebreaker Eddie Somers in May to the Maryland Department of Natural Resources. The boat was designed by BMT Designers & Planners Inc., Arlington, Va. It features a 4'6" draft and a 157 LT displacement. The boat is serving as the primary icebreaking asset for Crisfield Harbor and Smith Island, in addition to placing buoys and performing additional functions. The Department of Natural Resources' hydrographic operations team, based on the eastern shore, operates four large boats that perform various duties throughout Chesapeake Bay. The department's boats are shallow draft, enabling them to enter rivers and shallow areas of the bay. The Somers is a lifeline to Smith Island when the waters surrounding it freeze over, clearing a path for supply and shuttle boats. Main propulsion comes from twin Cummins QSK19, Tier 3 diesel engines, producing 750 hp at 1,800 rpm, supplied by Cummins Northeast. The mains hook up with Michigan Wheel 42"x27", 5-bladed nibral props through Twin Disc marine gears with a 2.48:1 reduction ratio. The propellers come from New England Propeller, the gears from North Atlantic Power Products. The propulsion package gives the new boat a running speed of 10 knots (loaded) at 1,650 rpm and a top speed of 12 knots. |
