Something hard and smooth was pushing against the skin of Jack’s back—the hull-planks of the galleot! He could not tell up from down. But those clinkers were lapped one over the next like shingles, and by reading their edges with one hand he knew instantly which way was down towards the keel, and which was up towards the waterline. Swimming, fighting his own buoyancy that wanted to stick him against the hull, he finally broke the surface and whooped in air, baying like a hound.
