Salt-water boils - red, angry, disfiguring - were a leprosy of the high seas, transmitted by the water that soaked me. Where they burst, my skin was exceptionally sensitive; accidentally rubbing an open sore was so painful I would gasp and cry out. Naturally, these boils developed on the parts of my body that got the most wet and the most wear on the raft; that is, my backside. There were days when I could hardly find a position in which I could rest. Time and sunshine healed a sore, but the process was slow, and new boils appeared if I didn't stay dry.
