MorBanz Special-Frequency

Antennas Available

From Morad Electronics

Morad Electronics of Seattle,

Wash., has announced the availabil- ity of its line of special-frequency

VHF/UHF marine antennas—

MorBanz antennas.

The MorBanz commercial grade antenna is custom-built to a 4-MHz bandwidth within the 102-MHz to 850-MHz ranges.

These antennas are specially de- signed for marine use and are made of materials similar to the company s 156HD 6dB "Hot Rod," which is a standard VHF antenna in severe environments such as Alaska. The antennas are built of stainless steel and anodized aluminum and re- ported resist corrosion and break- age.

Morad also builds custom, single- frequency antennas in the 2-30-MHz band.

AWO Sponsors 'Lifelines'

Tug And Barge Industry

Boating Safety Campaign

Lifelines is the tug and barge industry's new campaign for boat- ing safety. This campaign is aimed at educating recreational boaters, water skiers, wind surfers, jet ski- ers and others about the hazards of operating near tugs, towboats and barges.

Lifelines is sponsored by The

American Waterways Operators (AWO), the national trade associa- tion of the inland and oceangoing tug and barge industry.

According to statistics almost 60 percent of all accidents involving commercial and pleasure vessels are cased by a lack of knowledge, poor execution of a maneuver or careless- ness—a situation AWO wants to help correct with its Lifelines safety bro- chure for recreational boaters.

The Lifelines boating safety pro- gram reportedly has been accepted by the U.S. Coast Guard, the U.S.

Power Squadrons and Boat/U.S.

More detailed information on avoiding an accidental meeting with a tugboat or towboat can be obtained by sending a self-addressed, stamped envelope to: Lifelines, the Ameri- can Waterways Operators, 1600

Transtema, Stena Introduce

New Ship/Shore Data Link

Transtema Communication and

Navigation AB, of Gothenburg, Swe- den, has developed a new marine data link (MARIDAL), in partner- ship with the Swedish ferry opera- tor AB Stena Marine. MARIDAL is a multiuser system that allows shoreside computer networks to be linked directly to a shipboard net- work.

Depending on the area coverage needed, MARIDAL selects a VHF radio frequency for long range com- munications and UHF for short dis- tances. The system is designed so that a network of onshore base sta- tions can be utilized.

The Stena Jutlandica will serve as the trial ship for MARIDAL on its run between Gothenburg and

Fredrikshavn, Denmark, with re- sulting data laying the foundations for building a complete network.

Together with the Swedish Space

Corporation, Transtema is planning the first installation of a high speed, 64 kbit/second, data link from shore to ship using the Tele-X satellite system, a high-power satellite cov- ering Scandinavian waters. The ship terminal is 1.8 meters in diameter.

A Stena Line ferry sailing be- tween Gothenburg and Kiel will re- ceive the first fully operational in- stallation. In addition to telephone services and data for MARIDAL the system will be used to evaluate, dem- onstrate and market the new ser- vice.

Maritime Reporter/Engineering News "The most successful ships "When our new 70,000 GRT 'Fantasy' class of cruise ships were on the draw- ing board we investigated different machinery concepts. It was soon found out that the power station concept, based on medium-speed diesels and a state-of- the-art AC propulsion system, was the way to proceed.

ABB Marine was selected as the main contractor for the electric propulsion and power plant, because they are by far the most exper- * . 1 A 1 " ienced suppliers of electric propulsion systems in the world. Recordings Since me illK made during the sea trials had already proven that noise and vibration levels lay far below those occurring in any direct-driven ship today. The Fantasy manoeuvers beautifully even in heavy weather conditions in the narrow pas- sage to Freeport, Bahamas. The possibility to run at any time a selected number of prime mover diesels at their optimum keeps our fuel and maintenance costs low. Adequate combustion also means cleaner exhaust emissions.

The ABB Cyclo plant has proven itself to be extremely reliable in operation. Very few minor faults have been recorded. When this occasionally has happened, the Miami-based ABB Service crew and manufacturer have been quick to respond and helpful.

All in all, 1 am impressed by the ABB Cyclo propulsion concept."

We, too, are proud to be part of the four most successful ships since the Ark. 126

Cruise Lines. The Fantasy and her sister ship the Ecstasy have both exceeded our expectations, in terms of bookings and operation of the machinery. At Carnival, we often use the expression "the most successful ships since the Ark". Consequently, we have ordered two additional identical vessels, Sensation and Fascination.
