'Birgit-N'— First Crabber/Trawler

From Tacoma Boatbuilding

For Bering Sea Service deck are protected by watertight doors.

The efficiency of the Birgit-N's design is enhanced by the use of two 10-ton cranes, both fabri- cated by Northern Line Machine, a division of Tacoma Boat. The forward crane has a reach of 36 feet, and will serve as the picking boom. The aft crane is a unique level luffing design with a reach of 48 feet. The level luffing fea- ture of this crane allows the op- erator to raise and extend the boom without the need to con- stantly pay out or haul in line.

No matter how the boom is ma- nipulated, the line length remains fixed. This arrangement is safer, faster, and more precise than ex- isting installations. Both cranes are controlled by hydraulic servos on the main control valves which are located in the engine room.

The boat is also equipped with a pair of trawl winches, a stern

The newly christened fishing vessel Birgit-N is the first crab- ber/trawler built by Tacoma Boat- building Co., Inc., Tacoma, Wash., for service in the Bering Sea.

The Birgit-N (shown above) was built by Tacoma Boatbuilding Co.,

Inc. for Peter Njardvik and A.O.

Nordheim to join their other ves- sels in the rigorous and highly competitive Bering Sea crab fish- ery. The design, by B.F. Jensen and Associates, incorporates sev- eral features improving the effi- ciency of the vessel.

The Birgit-N has four crab tanks, each tank being insulated with 6 inches of closed cell ure- thane foam. The four-tank ar- rangement allows for ease of load- ing crab, and also facilitates han- dling of salmon when the vessel acts as a tender during the Alas- kan salmon season. A 60-ton re- frigeration plant is installed to maintain fish in the tanks at a temperature of 30F in chilled seawater. Sumps located in the forward tanks and a sliding wa- tertight door between tanks will allow rapid discharge of the fro- zen salmon via a fish elevator through the forward tank hatches.

A major benefit of the four- tank arrangement is a shaft alley allowing access from the engine room to the steering compart- ment and lazarette below decks.

The circulation pumps are located in the shaft alley, thus leaving more usable space in the engine room. All compartments below the
