With less than half a day left in the Alaskan king crab season, the crews race the clock to get as much crab into the holding tanks as they can. Bad luck and mechanical malfunctions still plague some captains, who need to land a certain number of crabs just to cover their operating expenses, much less to turn a profit for the crew.As the midnight deadline marking the end of season closes in, the battle to unload begins. Boats are unloaded at the processing plants on a first-come, first-serve basis, and a couple of minutes can mean the difference between unloading immediately, or waiting in the harbor for days.
