The Lake Pilots Association, District 2, in Port Huron, Mich., has accepted delivery of Huron Spirit, a new Chesapeake Class pilot boat from Gladding-Hearn Shipbuilding, Duclos Corporation

 
With a length overall of 52.5’, a beam of 16.7’, and a draft of 4.8’, the all-aluminum pilot boat features the C. Raymond Hunt-designed Deep V hull. It is powered by twin Cummins QSM11 diesel engines, each delivering 602 Bhp at 2300 rpm and a top speed of 25 knots. A Humphree interceptor, with automatic trim optimization, is installed at the transom. Diesel capacity is 690 gallons, which, shipyard officials say, will provide a range of at least 350 miles at an economical speed of about 20 knots. 
 
The engines turn 5-blade NiBrAl propellers via Twin Disc MGX-5114A “Quickshift” gears.
 
The wheelhouse, flush-mounted to the deck amidships and with forward-leaning front windows, is outfitted with Llebroc seats and a settee and is heated by two Heatercraft 40,000 Btu units. The forecastle also includes a 40,000 Btu heater, along with a settee, portable head, and built-in storage cabinets. 
 
Outside of the wheelhouse, the handrails and foredeck are heated by a 120,000 Btu diesel-fired heater. There are boarding platforms on the roof and port and starboard on the foredeck. At the transom are throttle and steering controls, and a winch-operated, rotating davit over a recessed platform for rescue operations.
