Marine Management Develops Demo Programs Marine Management Systems (MMS) has developed demonstra- tion programs for its Spare Parts Inventory Management and Planned Maintenance computer ap- plication software. The demo pro- grams will run on any IBM PC to demonstrate the capability of MMS software and operational reports available. According to Don Logan, MMS vice president, "These demonstra- tion programs give our potential clients a very realistic feel of how effective and simple our systems are to operate in a typical maritime environment." MMS, based in Stamford, Conn., is a leader in providing computer- ized management information sys- tems, since 1969. The company deals exclusively with the shipping industry to provide services in the areas of shipboard and shoreside application systems, maritime infor- mation and management consult- ing. The demonstration programs are available without charge to quali- fied prospects.

A pair of Marco combi- nation crabbers built in 1979—the 122-foot Columbia and the 123-foot American Beauty (ex-Northern Leader)—had extensive modifica- tions made for their new fishery roles. Work completed on the Columbia included a pair of new Marco WT266 MarTrawl winches and the IntelliTrawl computerized trawling system, fabrication of a stern ramp and 10-inch recessed roller, 8-foot- wide net flat, trawl door pockets, box-style stern gantry, net reels, hy- draulically actuated stern ramp gates, extensive hydraulic and elec- trical systems work along with pow- er supply changes, DC41 HPD with AirKlutch to better handle the re- quirements of the trawl machinery, Rapp net sound winch, Pullmaster haulback winch, two Pullmaster large-drum gilson winches, and an aft-facing console added to the pilothouse with controls for the en- tire trawling system. The Columbia's propeller was re- pitched, chafing guards were added, engine room and exterior painting was done, and an extensive list of electronics was installed by Harris Electric, including Simrad ES-380 echo sounder, Simrad FA-100 catch June, 1985 indicator, ET-102 sounder with FR- 500 Trawleye system, and a Furuno FCT-1411 color radar coupled with the GD-2000 color plotter. In addition to having much of the same work performed, The Ameri- can Beauty opted for a pair of Rapp TWS-f220 trawl winches, and the Autotrawl system, Rapp net sound winch, two Gearmatic gilson win- ches and Gearmatic inhaul winch, conversion of the Marco DP37 HPD on the Cat main engine to a DC37 with a 14-inch AirKlutch and the addition of a DG41 HPD on the starboard Cat 3408 auxiliary. Other items included a trawl console in the pilothouse, stern ramp wear plate, bin board guides, and hull and en- gine room painting. Owner-furnished electronics were installed by Lunde Marine Elec- tronics, including Simrad EQ echo sounder, FR-500 Trawleye system, and FA-100 catch indicator, plus a Raytheon NWU-50 color video plot- ter and NOM-50 tape data record- er. An inclining experiment and sta- bility report were provided for both the Columbia and American Beauty upon completion of their conver- sion.

Harris' field-proven RF-2331 channelized ARQ system assures that the data you depend on will flow smoothly The RF-2331 is an advanced synthesized (transmitter/receiver) automatic error cor- recting HF radio teletypewriter system, designed for easy, channelized marine telex and data operation. Output power is 125 watts for voice and ARQ operation. A unique high-speed switch allows operation from a single antenna for transmitting and receiving, eliminating on board self-interference problems. For fully automatic operation, an optional channel scan control can be added. In dollar terms, the RF-2331 is extremely cost effective compared to a satellite system.
