ADF&G (Alaska Department of Fish & Game) has a great little 2 page PDF about commercial fishing boats. You can download it here:
Types of Boats
Boats & Bits
Rolling Chock
Rolling chocks are “fins” on the hull that provide additional stability in the waves.
Homer Crane Dock
Seiners unloading at the crane dock in Homer, Alaska
Full Hold
Looking down from the cannery (fish processing plant) dock, onto the deck of a seiner with a full hold of salmon. On the bottom of the image, the round metal with a long handle and orange net is the brailer. The corkpile is on the stern port side, net in the center, leadline on the starboard side. At the top is the skiff. The oval metal on the bow side of the fish hold are hatches to the engine room.
Rafting Boats
Rafting boats is an easy way to protect all the boats. On the left is a Hamm, next to it is a Modutech. The larger boat is a Ledford and the aluminum boat on the right is a jitney.
The Galley
The galley only fits one person. Starting from the left: the steep steps going from the cabin floor to the deck. The cupboard doors open to reveal the engine. Above, on the countertop, is a propane camp stove. When the boat is working, the stove is plumbed to a 7 gallon propane tank. Next is the sink, which barely holds 2 coffee cups. The cupboards above hold food used daily, like bread and coffee, and plates. Opposite, in the corner, is a drip-oil stove that is used for heating the cabin. Under the counter at the bottom, center, is a small refrigerator. When the boat is working there is a small chest freezer on the flying bridge. Both fridge and freezer run off the inverter, which charges batteries via solar panel and the main engine.
