Kinda small to be a crab boat. And there’s no launcher, coiler, or recovery block. ‘Tisn’t crab they be after, mate.
Kupreanof is (Was) a tender. About 75 or 80 feet IRRC. Homeport here in Petersburg. This type of boat would deliver groceries, ice and fuel to the smaller gillnetters, longliners, purse seiners, trollers and crab boats in outlying anchorages and pick up their catch. The consolidated catch, whatever, would be taken back to Petersburg for processing.
