Electric power for the winch drive, steering unit control and all shipboard services is pro- vided by a pair of 95 kw, 230/3/60 AC genera- tors. Mitsubishi 6D16-T auxiliary engines each drive a Simpower B254C alternator.

The winch drive and Z-drive steering motors are controlled by Mechtronics 59000 series fre- quency modulating motor drives, to achieve a full range of variable speed control from the AC power supply.

The ship-handling operations of the Charles

H. Cates X are carried out from the fore deck, utilizing a single-drum variable speed electric- driven line-handling Burrard Iron Works winch.

The Burrard winch stores a 400-foot 2-1/2-inch- diameter Round Plait Polyester Samson Braid towing line.

The all-steel Cates X will operate in Vancou- ver Harbor providing ship assist services.

Bestway Systems Develops

Ship-Based Computer Systems

For Private/Commercial Sectors

Bestway Systems, Inc. has developed ship- based computer systems for both the private and commercial sectors. A special chassis has been hardened to withstand abnormal tempera- ture, humidity, dust, vibration and shock ex- tremes. Based on Interactive's UNIX/ix, the platform is mated with fiber optic terminals, bringing EGA capability to all users, whether business or scientifically oriented.

The chassis, a standard 19-inch rack mount, is combined with a likewise mounted computer- ized UPS system which interacts directly with the operating system. Communication with land-based hosts is achieved over modems via satellite link. Up to 12 users per node are possi- ble, with multiple nodes in a TCP/IP network.

Targeted for private yachts 100 feet and greater, and commercial vessels, the systems are expected to be available in the second quarter.
