Oh, yes, yes, indisputably, we still needed the drain plug. As long as we kept running along at half throttle or better, no water could enter the boat. But once we stopped to land the fish or when we, inevitably, ran out of gas, we would start sinking without delay. It was news to me that it had not only come dislodged from its hole but had gone missing entirely. If it was not under the floorboards, that would be additional news of a very bad kind. It was also news, of a surprising sort, that our drain plug was suspected of floating, since such items are customarily constructed of such sinkable materials as brass and hard rubber. If it comes out, it falls to the bottom of the boat and you pick it up.
