UPDATE

Cummins-Powered 'Traktor Jet' Gives

Workboats Unprecedented Thrust

Developments in the Raytheon

R61 Rasterscan Radar's Interfer- ence Rejection, and Rain/Sea Clut- ter technology have led to even greater reduction of interference from weather and other radars.

R61's advanced video processing circuitry further improves the bright, sharp picture Raytheon ra- dars are known for.

Ideal of workboats, fish boats and other similar vessels, the new 64- mile R61 is described as "a work- horse radar with thoroughbred tech- nology." The unit features super- sturdy, reliable construction.

At the same time, the R61 pro- vides an impressive array of capabil- ities.

Using touch controls, an R61 operator gets alphanumeric read- outs of vital information. For exam- ple, the Electronic Bearing Line (EBL) and Variable Range Marker (VRM) provide fast, accurate bear- ing and distance information.

Another important feature, Sea-

Guard, warns of collision danger, marks points of intrusion into user- selected guard zones, and sounds an alarm.

Raytheon's unique on-screen tun- ing bar enables the operator to tune the radar simply and quickly.

A "Target Expander" enhances weak signals.

The R61 has a 12-inch diagonal,

Raytheon's R61 Rasterscan Radar. 512-line high-resolution screen. It comes with a 6-foot or 4-foot anten- na, with 1.2-degree or 1.9-degree ho- rizontal beamwidths, respectively.

Raytheon offers a two-year lim- ited parts warranty with one year free labor by any of its U.S. dealers and worldwide service network.

NAVSEA Awards Anadec $9.5-Million Contract

Anadec, Inc., Arlington, Va., was recently awarded a four-year, $9.5- million contract by the Naval Sea

Systems Command to support the acquisition of the U.S. Navy's AN/

BSY-1 combat system.

Shallow-draft workboat opera- tions are beginning to be revolution- ized with the introduction by North

American Marine Jet Inc. of Ben- ton, Ark., of a new diesel-powered waterjet propulsion unit that pro- duces more than 3,000 pounds of static thrust at 150 horsepower.

Tradenamed the "Traktor Jet" be- cause of its pulling power, the unit is powered by a Cummins 4BT3.9-M diesel engine developing 150 horse- power at 2,800 rpm.

The Traktor is ideal for fishing boats and workboats where thrust is more important than speed. Other waterjet propulsion units are more suited for high-speed boats than for vessels needing maximum thrust at low speeds. The 18-inch axial flow jet propulsion unit can pump six (55-gallon) barrels of water per sec- ond.

Following extensive research,

North American determined that

Cummins was best for the propul- sion unit's power source. Among the

Cummins 4BT advantages were the engine's high horsepower (150) to weight (860 pounds) ratio, its low fuel consumption (7.6 gallons per hour at rated speed), competitive purchase price, and the fact that the engine is manufactured in the U.S.

Leonard Hill, president of

North American Marine, said he prefers to have ail-American compo- nents in the Traktor package be- cause of the availability of parts and service. He noted that Cummins has set up special service centers, which

Marine Jet Inc., points out the features of the Traktor Jet Skid Pack unit.

The first production model of the Cummins- powered Traktor Jet was installed in the completed seine skiff Kodiak King.

The Imperial Suit Has Saved

More Lives Than Any Other

The details are different-but the end result is the same: People who wore an Imperial

Suit lived! Imperial kept them afloat and warm.

One oil rig worker thanked us for saving his life after a hurricane-driven 50-foot wave swept him into the sea for over 20 hours.

In another documented case, four men to survive nine hours in 35 F water and 25 hours on a frigid beach. A pilot who put an Imperial Suit on before he ditched his single-engine plane was rescued in the icy

North Atlantic after 10 hours.

So far, more than 400 people have informed us they cheated death by wearing Imperial

Suits. And that's a small percentage of those who actually put their Imperial Suits to the test.

Imperial is The World's

Best Selling Immersion Suit

There are more than 100,000 Imperial suits in use. With good reason. Imperial's suits are built better. Extensive research and development plus testing of every suit continuously upgrades performance. Our customer service and satisfaction is second to none. And we provide complete education and training both in person or on videotape.
