A sturdy, small fishing-boat wallowed and rolled and heaved and pitched in the huge slow swells of mid-Pacific. It looked very much like any other fishing-boat and remarkably like those tuna-boats that put out from the West Coast of the United States and pursue their prey for as many thousands of miles as may be necessary.
It was just a little over a hundred feet long and was powered obviously by a Diesel engine. There was just one thing odd about the boat and one oddity about its crew and one about the object it towed and one about its wake.
