The fish weren't biting.
The doughty crew of Nausikaa had done their best, keeping the ship's two fishing lines baited, experimenting with this lure and that. A clothespin attached to each line was poised to snap shut if a fish tugged on the line.
But days passed on the open ocean with no sign of fish and nothing snapping on the line. Then one day--snap! Something was on the line. Prepared for a fight, they hauled in the heavy line to find--a pair of jeans that had been hung out to dry and blown overboard.
Boris couldn't help remembering what the clerk at the fishing tackle store had said back in Victoria when they were laying in provisions: "There are no fish out in the open ocean. Fish only go out about 200 miles into the Pacific and that's it." Maybe he was right. Maybe out here in the trackless ocean, there just were no fish in the sea.
