Marco-Seattle Converts Two Combination Crabbers For New Fishery Roles

As a result of the move to trawling in the North Pacific fleet, two of this year's more complete conversions took place at the Marco-Seattle shipyard. A pair of Marco combination crabbers built in 1979—the 122-foot Columbia and the 123-foot American Beauty (ex-Northern Leader)—had extensive modifications 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-footwide net flat, trawl door pockets, box-style stern gantry, net reels, hydraulically actuated stern ramp gates, extensive hydraulic and electrical systems work along with power supply changes, DC41 HPD with AirKlutch to better handle the requirements 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 entire trawling system.

The Columbia's propeller was repitched, 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 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 American Beauty opted for a pair of Rapp TWS-f220 trawl winches, and the Autotrawl system, Rapp net sound winch, two Gearmatic gilson winches 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 engine room painting.

Owner-furnished electronics were installed by Lunde Marine Electronics, including Simrad EQ echo sounder, FR-500 Trawleye system, and FA-100 catch indicator, plus a Raytheon NWU-50 color video plotter and NOM-50 tape data recorder.

An inclining experiment and stability report were provided for both the Columbia and American Beauty upon completion of their conversion.
