The Honda Point Disaster was the largest peacetime loss of U.S. Navy ships. On the evening of September 8, 1923, seven destroyers, while travelling at 20 knots (37 km/h), ran aground at Honda Point, a few miles from the northern side of the Santa Barbara Channel off the California coast. Two other ships grounded, but were able to maneuver free of the rocks. Twenty-three sailors died in the mishap.
The ships comprised Destroyer Squadron 11 (DesRon 11). The squadron, led by Captain Edward H. Watson, was heading from San Francisco to San Diego. Watson was on the flagship leading the squadron of fourteen destroyers. All were Clemson-class destroyers, less than five years old. The ships turned east, supposedly into the Santa Barbara Channel, at 21:00.
The ships were navigating by dead reckoning, estimating their position by their heading and speed, as measured by propeller turns. At the time radio navigational aids were new and not completely trusted. Delphy was equipped with a radio navigational receiver, but ignored the bearings, believing them to be erroneous. No effort was made to take soundings or depth measurements. These operations were not performed due the need to slow the ships to take readings. The ships were performing an exercise that simulated war-time conditions, hence the decision not to slow down. In this case, the dead reckoning was wrong and the mistake fatal.
Earlier the same day, the mail steamship Cuba ran aground nearby. Some attributed these incidents in the Santa Barbara Channel to unusual currents caused by the Tokyo earthquake of the previous week.
Ultimately, a Navy court ruled it was the fault of the Captain and navigators. They also assigned blame to the Captain of each ship, following the tradition that a Captain's first responsibility is to his own ship, even when part of a formation.
In order the ships were (bold marks lost ships):
The remaining four avoided the rocks.
There was one civilian aboard Delphy. Eugene Dooman was aboard as a guest of Captain Watson; they had first met in Japan. Dooman was a Japan expert with the State Department.
Honda Point, also called Point Pedernales, is located outside of Lompoc, California. It now is part of Vandenberg Air Force Base. There is a plaque and a memorial at the site.
