What Jack has in the boat with him isn't much. A few bottles of rum, the torn out bit of Sao Feng's map, an empty sack that once held the tiny bit of food he brought, and a plank of wood. His emergency paddle. As he listens to the creatures move around the boat, this seems to be the most useful thing he has on him. Paddling seemed foolish before, as he would wear himself out long before reaching shore. But now, it seems a bit more reasonable.
He still has his 'paddle' poised above water as he goes stalk still and watches the blond rise from the waves and fall again. They're truly amazing. Would be more so if they didn't want to eat him.
"Sorry, girls. Can't stay for supper. Do hate t'disappoint, but I've places t'be. Savvy? ... Wind! Where's the bloody wind?!" He blows at the sail again as he starts paddling frantically. The paddle isn't large enough to do him much good.
