Struck by a cyclone in a Samoan harbor in 1889, the U.S. warship Trenton had lost steam and rudder and was in danger of foundering on a reef when her navigator, Robert M.G. Brown, thought of an inventive solution: The crew climbed into the port rigging, where their massed bodies acted as a sail. The ship was able to avoid the reef and even approach the sinking sloop Vandalia to rescue her crew. Of the 450 men aboard Trenton, only one was lost.
