Sixty years ago today, the January 16, 1962, issue of the Washington Evening Star carried this feature by its outdoor editor about one of the stars of the New York Motor Boat Show. This craft was touted as a seagoing fallout shelter. The craft was from the Wheeler Yacht Company, which had teamed up with a name familiar to students of television history, namely Dr. Allen B. Du Mont, one of the pioneers of television.

The principle behind using a boat is sound, as described by Du Mont. Fallout is almost invariably heavier than water, and sinks to the bottom. If the water is 10 feet deep, this means that there is 10 feet of water between the fallout and the boat, which is equivalent to 3 feet of earth, giving excellent protection. Of course, fallout might have settled on the boat, so it was equipped with nozzles for cleaning the deck. Fallout on shore was dealt with through distance, by keeping the boat a minimum of 750 feet from shore. Of course, the ship did nothing to protect against blast and fire, and noted that it would need to be at least 35 miles from ground zero at the time of blast.

For a more detailed look at the concept of using boats for fallout protection, see the 1963 report from the U.S. Naval Radiological Defense Laboratory, Civil Defense Utilization of Ships and Boats.
