traditionl sea water piping, heat exchangers and keel-cooled main engines prevent sea-water corrosion by eliminating thru-hull fittings. A 1,000-gallon, remote-controlled bal- last tank increases the vessel's sta- bility in extreme sea conditions.

The vessel also features aft-sta- tion steering and control for greater visibility in the case of a person overboard, and water-level rescue steps recessed into the transom.

Vessel:—

Type: OSRV

Yard: Kvichak

Kvichak Marine Industries has built 12 OSRVs for the National

Response Corporation (NRC).

During sea trials for the first boat which were conducted in June, NRC

National Equipment Manager Bob

Governale said, "We specified a boat that was cost-effective, yet safe and functional for multi-tasking, and expected a compromise as a result.

Much to our surprise and delight, though, we have a vessel that ... exceeds expectations."

The all-aluminum handling/skim- mer support boat is 28 feet long, with a beam of 11 feet and a depth of approximately six feet. It is pow- ered by a 300-hp Caterpillar 3116 diesel, driving a 28- by 24-inch four- blade stainless propeller through a

Twin Disc MG 5061 2.43:1 reduc- tion gear. In addition to a speed of about 16 knots, the vessel achieves a bollard pull rating in excess of 4,500 lb. Other features of the

Kvichak design include a fully-en- closed pilot house for all-weather operations, a mechanical davit with winch, a tow post, push knees and full-perimeter, four-inch D-rubber.

Construction is of marine-grade alu- minum throughout, with 1/4-inch hull and side plating, 3/8-inch chine plate, and 3/16-inch decking. "We're very proud of this vessel and the way it performs," commented

Kvichak Vice President Keith

Whittemore. "Working with the

NRC people has been a real plea- sure. They knew what they wanted and they've worked very profession- ally with us to achieve their goals."

Type: Survey Vessel

Yard: Munson Mfg.

The U.S. Geological Survey divi- sion, located in St. Petersburg, Fla. , needed a vessel to fit its specific geological survey requirements.

That boat was designed and built by

Munson Manufacturing, Inc. of

Edmonds, Wash.

The Geological Survey 42 will allow the survey teams to operate in both deep sea and shallow draft areas with live-aboard capabilities.

It is outfitted with three 6V53TI 400-hp, 2,800-rpm Detroit Diesel engines with Twin Disc gears, three

Hamilton 291 jets, Hynautic dual station triple controls, and a 400- gallon fuel capacity. Other equip- ment aboard includes a Hiab SEA 60 crane, Vickers 12.0 GPM pump, two 12 kW Onan generator sets with paralleling circuit panels, computer test work benches, removable aft

Near-Perfect

Target Detection.

Using increased signal-to-noise levels, high dynamic range, precisely matched pulse bandwidths, and exclusive Rain

Rate circuits, PATHFINDER/ST receiv- ers faithfully capture target returns even in severe clutter.

PATHFINDER/ST multistage processing analyzes, compares, tests, and samples the received signal so that all detected targets, no matter how weak in signal strength, are distinguished from clutter and clearly displayed.

From the control panels through the computer, transmitter, and receiver-and then in five steps leading to the CRT-

Raytheon's exclusive Superior Technology provides sharp, bright radar pictures virtually free of clutter.

PATHFINDER/ST ARPA: 34-cm or 25-cm

PPI's (16"or 12"diagonal CRTIMO equivalents), provide automatic tracking of up to 40 targets with vectors and readouts for most dangerous 20. Have auto and manual acquisition, and unique trial maneuvers.

PATHFINDER/ST TM/EP: 34-cm or 25-cm

PPI's (16"or 12"diagonal CRT IMO equivalents), have True and Relative

Motion displays. Electronic Plotting, course, speed, bearing, range, CPA, and

TCPA for two selectecTtargets.

Superior Target Detection.

True Motion with

Electronic Plotting or ARPA.

Raytheon sets radar performance stan- dards for the 21st century with technolo- gy breakthroughs that virtually eliminate noise, interference and clutter, while rec- ognizing and displaying even weak tar- gets typically lost on other radars.

The heart of this improved radar system is Raytheon's exclusive five-stage signal processing...we call it Superior

Technology.

ST for short.

Combined with higher performance transmitters and receivers, and the latest raster displays, ST provides performance levels never before available. Now, with

PATHFINDER/ST, your vessels-and their crews-can have an important extra mea- sure of safety and efficiency, including a unique Safety-Coded CPA Circle, which shows course selections for safest CPAs.

PATHFINDER/ST is available as an

ARPA or a True Motion/Relative Motion display with Electronic Plotting. These displays can easily retrofit the displays in older Raytheon Bright Display Radar

Systems, and can be high-performance repeaters for radars of most other manufacturers.

Simple Installation and Flexible System

Configuration.

PATHFINDER/ST Radars satisfy a very wide range of installation and operating requirements. Signal multi- plexing reduces connections between

PATHFINDER/ST receivers and dis- plays. This, combined with electronic interswitching for dual systems, the abil- ity to mount transceivers "up" in antenna pedestals, or "down" in separate cabi- nets, and keyboard entry of all set-up parameters, makes any installation straightforward, simple, and economical.

In addition to having the optional IMO- required, antenna-mounted performance monitors, PATHFINDER/ST Radar soft- ware provides menus for extensive self- testing of virtually every function.
