Idaho, a single-screw, wooden-hulled motor boat built in 1907 at Marblehead, Mass., by Stearns & McKay; was acquired from her owner, W. W. Vensel of Pittsburgh, Pa., under a free lease and delivered on 12 July 1917. Idaho, given the identification number S.P. 545, was commissioned at Cape May, N. J., on 12 July 1917, CQM William H.
