Hunt Associates And Gladding-Hearn

Collaborate On Pilot Boat Design

C. Raymond Hunt Associates, de- signers of Boston, and Gladding-

Hearn Shipbuilding Corporation of

Somerset, Mass., have collaborated on a fast, twin-diesel, all-aluminum pilot boat for the Sandy Hook Pi- lots. The construction contract was awarded to Gladding-Hearn in De- cember 1984, and delivery is sched- uled for this summer. She will re- place an aging and slow steel-hulled dispatch boat.

The Sandy Hook Pilots wanted a fast boat to cut the commuting time from base to station from one hour to half that time. The boat had to be comfortable and capable of going in any weather all year round into the

North Atlantic to transport some 12 pilots plus crews in safety to the sta- tion vessel. Finally, the new boat had to be capable of standing in for one of the big station vessels for up to two days in the event that one of them is out of service for repairs in a shipyard.

Hunt Associates and Gladding-

Hearn came up with this 64-foot, 20-knot, deep-V-hulled boat, cus- tom designed to do the job. This design is a larger sister to nearly a dozen other Hunt/Gladding-Hearn pilot boats operating on the East


The boat has a beam of 17 feet (plus 6-inch rubber fender) and a draft of 5 feet 6 inches. Fuel capac- ity is 1,500 gallons, and 200 gallons of potable water can be carried. Her normal role is as a dispatch/com- muter boat from the shore base in

Staten Island, N.Y., to the boarding station 12 miles at sea.

In the event that this boat has to be pressed into service as a relief station vessel, she can take aboard another 1,000 gallons of fresh water as ballast to give her the stability of a much larger vessel while holding station off the Port of New York.

Main propulsion power is provided by twin M.A.N.-B&W diesel engines delivering a total of 1,080 bhp at 1,800 rpm.

She will carry two Furuno radars, three Shipmate VHF sets, a North- star Loran C, and two depth sound- ers, including a survey grade Ray- theon for sounding docks, ap- proaches, and suspect areas. Other equipment includes two Northern

Lights gensets, air starting for the main engines, extensive sound insu- lation, and accommodations for six pilots and four crew.

Pilots will board from the main deck forward, within complete view of the raised pilothouse, which is arranged amidships and has 360- degree visibility. A complete naviga- tion bridge imitates the bridge of a much larger vessel.

Of particular interest are the safe- ty systems incorporated into the de- sign at the request of the Sandy

Hook Pilots. Pilots worldwide are sharing information on how to make the very dangerous job of boarding ships at sea safer. The New York-

New Jersey Pilots decided to adopt several features suggested by their fellow pilots. Recessed into the transom is a platform near the wa- terline that would allow a conscious man in the water to pull himself aboard or be aided aboard by crew- men.

Johnson-Duramax Stuffing Boxes

Make Packing Changes Easier

A line of maintenance-reducing stuffing boxes is now available from

The Johnson Rubber Company's

Duramax Marine Division. In addi- tion to making packing changes eas- ier, several of the company's, heavy duty stuffing boxes are specifically designed to cut the need for dry- docking.

Three of the popular types of stuffing boxes feature the exclusive

Duramax inflatable "Air Seal" rub- ber ring which, when inflated, seals itself around the shaft sealing out water when a packing change is required. Packing can be changed even while in the water, eliminating the need for drydocking. When the repacking is complete, the inflated seal is deflated. At this point, the rubber ring automatically retracts clear of the shaft.

The company offers a broad line of stuffing boxes for many marine applications. For service at forward stern tube locations, stuffing boxes with shaft sizes ranging from 2% inches to 15 inches provide water/ grease lubrication, grease lubrica- tion or water lubrication. Made of cast naval bronze, Duramax stuffing boxes are engineered for extra strength at critical stress points and are precision machined with female recess for mating with Duramax water lubricated flanged type bear- ings. Stuffing boxes with machined male pilot for use with the Duramax water-lubricated demountable rub- ber stave bearings are also avail- able.

Split type stuffing boxes, as well as boxes of cast aluminum or mild steel are also available in certain models and sizes.

Bulkhead or rudder stuffing boxes ranging in shaft sizes 2% to 7% inches are offered in bronze and can be supplied with integral steel flanges for bulkhead welding. Also offered in the line are a series of bronze stuffing boxes and stern castings for shaft sizes ranging from 1 inch to 6 inches, featuring rugged construction with thick mounting flange and thick ribs for better shaft support.
