introducing its new magnetic auto- pilot, the NAVIPILOT V/M, which is being aimed at the workboat,

OSV and under 90-foot yacht mar- k.6ts

The NAVIPILOT V/M is designed for those operators who do not find it cost-effective to have a complete gyrocompass system onboard, yet need accurate heading information to guide peripheral equipment.

During installation, compass de- viation is stored and corrected in the pilot's memory and during daily op- eration, local variation can be easily changed by the operator. The result is a corrected magnetic heading that is remarkably close to true.

Radio Holland, with its U.S. head- quarters located in Houston, Texas, has established a complete program for maritime GMDSS stations, in- cluding GMDSS equipment, shore- based maintenance and radio traffic accounting with air time cost-sav- ing programs.

Aii SP Radio (Sailor) integrated communications console combines all GMDSS-required radio elements into a compact, state-of-the-art pack- age, designed to be installed on a vessel's bridge.

Radio Holland's GMDSS pack- age also includes a qualified short based maintenance program thf supports worldwide operation £ dramatically reduced costs and n dio traffic accounting, with optionc

Inmarsat air time packages avail able for further savings.

System installation can be ac complished at ports throughout th world with operator training avail able aboard ship and at shore loca tions.

The Radio Holland GMDSS sys- tem, in conjunction with Kelvir.

Hughes "Nucleus" radars and inte- grated bridge components, is de- signed to improve efficiency and safety.

RD INSTRUMENTS

To simplify vessel maneuvering in port, RD Instruments, of San Di- ego, Calif., enables pilots to consult a comprehensive water current monitoring network using the company's Acoustic Doppler Current

Profilers (ADCPs) dispersed along the port's traffic channels.

These instruments are mounted on the seabed to avoid interfering with vessel traffic. Once a second, each ADCP remotely measures wa- ter current speeds throughout the water column.

These measurements are commu- nicated to the pilot's office where they are instantly summarized by a computer.

This synopsis is then relayed to the pilots aboard vessels entering or leaving port so they can allow for currents that affect their vessel's movements.

Several ports around the world, including Keppel Harbor in

Singapore and the Port of Tampa

Bay in the U.S., are presently using

RD's ADCPs to monitor water cur- rent speeds in shipping channels.
