Gladding-Hearn Shipbuilding, The Duclos Corp
., has delivered its 11th police boat for the New York City Police Department.
The new high-speed, all-aluminum deep V-hull, which measures 13 ft. abeam and draws 3.5 ft., is powered by twin Caterpillar 3208-TA diesel engines, each rated for 435 bhp @ 2,800 rpm, with a top speed in excess of 30 knots. The engines drive two 32-in. nickel-bronze propellers via Twin Disc 3:1 reverse/reduction gears and stainless steel shafts.
The vessel features extremely robust hull scantlings and shear guard. Engine water is circulated under the decks to keep them ice-free. The boat's transom is equipped with a door, leading to a fold-down rescue platform. Onboard accommodations, for a crew of four, include a small galley, enclosed head and two bunks. The boat's interior is cooled by an oversized air conditioner.
According to shipyard officials
, sound levels in the wheelhouse are below 80 decibels at cruising speed. Sound absorbent insulation is installed under the deck and against the engine room bulkheads. A combination of a sound-reducing air-intake system, which traps noise from interior compartments, and heavy-duty, vibration-absorbing engine mounts, further reduce engine noise.
