Electronic Marine Systems

Offers Free Color Brochure

On New GPS Chart Viewer

Electronic Marine Systems (EMS), of Rahway, N.J., is offering a free color brochure describing its new Ground Positioning System (GPS) Chart Viewer for marine navi- gation.

According to EMS, the GPS Chart

Viewer provides a GPS navigational format that is extremely useful to today's mariner.

The GPS Chart Viewer was de- signed to provide the navigator with the continuous position assessment that is critical in close quarters situ- ations and shallow or restricted waters, such as harbor areas. Accu- racy to within 10 feet inbound at the sea buoy is made possible by the

GPS Chart Viewer, which indicates the ship's position directly onto the chart.

The system resolves errors in po- sition accuracy caused by selected availability (SA) of satellites, as well as inherent GPS errors which could be as much as 100 feet.

By determining the exact loca- tion of the sea buoy with either vi- sual or radar fixes, the navigator can then position his "own ship" on the chart viewer to that precise loca- tion and from that point continue the vessel's track with extreme ac- curacy.

Congress Urged To

Support Towboat Law

Members of the House of Repre- sentatives are being asked to sup- port a bill introduced by Rep. Neil

Abercrombie, D-Hawaii, that would establish minimum manning and watch requirements for tow- boats.

At the moment, Coast Guard regu- lations only call for one tow vessel crewman to be present on the bridge to control the entire towing opera- tion, and despite the length of the voyage, the crew need only be di- vided into 2 watches.

According to Walter J. Shea, president of the Transportation

Trades Department, AFL-CIO, in the event that the lone crewman on watch becomes disabled or leaves the bridge for any reason, "the ef- fects would be devastating."

The Abercrombie bill would con- tinue to allow towing vessels to di- vide their crews into only 2 watches on voyages that are less than 200 nautical miles.

However, for longer voyages, all of the towboat's licensed and unli- censed crewmen would have to be divided into 3 watch sections if the bill becomes law. 4 SK66KOM 4'i Rope Master
