The first Shearwater, a steel schooner-rigged yacht, was built in 1887 by Hawthorne and Co. at Leith, Scotland, and purchased by the Navy on 9 May 1889 from H. R. Wolcott.
Loaned to the Pennsylvania Naval Militia on 31 December 1898, she served as a training ship at Philadelphia, Pa., until she was struck from the Navy list on 24 April 1908. She was sold in the fall of 1908 to Mr. Samuel B. Wilson and delivered to him at the Philadelphia Navy Yard.
Shearwater (AM-413) was laid down in 1945; however, the successful conclusion of World War II prompted the cancellation of her construction.
