Zigzag, a wooden-hulled motorboat completed in May 1916 at Stamford, Ct., by the A. E. Luders Construction Co., was acquired by the Navy from T. J. Backman of Bradenton, Fla., and delivered on 27 June 1917. Assigned the classification S. P. 106, Zigzag was placed in commission on 8 August 1917.
Assigned to the Seventh Naval District, Zigzag operated on section patrol duties for the duration of World War I and probably until the cessation of all defensive patrols on 24 November 1918. Subsequently, she lay anchored in the North Beach Basin, Key West, Fla., awaiting disposition when a hurricane battered the Florida Keys on 9 September 1919 and swept through the region with disastrous results.
The next day, eight section patrol boats, including Zigzag, were found completely wrecked, literally dashed to pieces on the seawall. Salvage crews later hauled the tangled wreckage from the water and burned it, retaining only the machinery to survey it for future disposal. Zigzag was stricken from the Navy list on 4 October 1919.
