A Volvo Penta IPS propulsion system will give a launch now building for the Galveston-Texas City Pilots a top speed of over 30 knots while burning less fuel than their existing boats.
The vessel will be the pilots’ fourth launch from Gladding-Hearn Shipbuilding, Duclos Corporation, Somerset, Mass. Delivery is scheduled for late 2022.
With a length overall of 73 feet 2 inches, beam of 23 feet 3 inches and draft of 5 foot 9 inches, the all-aluminum, high-speed pilot boat features the Ray Hunt Design deep-V hull. It will be powered by three Volvo Penta D13, EPA Tier 3 marine diesel engines, each delivering 800 bhp at 2,300 rpm, and integral to the engines’ triple IPS-Pod 1050 system. Top speed will be over 30 knots.
The vessel will burn 25% less fuel than the pilots’ existing 70-foot pilot boats at the same speed, according to shipyard officials.
Humphree interceptors, with active ride control, coordinated turn and automatic trim optimization, will be installed at the transom. A Seakeeper 30HD stabilizing gyro will be installed to reduce up to 80% of the vessel roll at all speeds.
The wheelhouse, mounted to the flush deck aft of amidships, features a center-line helm station with heated forward, side and roof windows, six Norsap shock-mitigating seats and a settee with table. Two Phasor 21kW generators will produce electricity.
The forecastle will include a stateroom with two berths, head, hanging locker, small galley and table with settees. HVAC will be supplied by six self-contained, reverse-cycle air-conditioning units, four 16,000 Btu units in the wheelhouse and two 8,000 Btu units located in the forecastle. Interior sound levels at full power will be under 75 dBA.
Outside the wheelhouse are wide side-decks and a flush main deck and on the foredeck aft of the wave break are port and starboard boarding platforms. A Harken safety rail system will be installed on the wheelhouse handrails. A control station is at the transom, along with a winch-operated J-Basket rescue system and recessed stairs and platform, for pilot rescue operations.
