Armament

The USS Alabaster (PYc-21) was a coastal patrol yacht of the United States Navy during World War II.

The ship was built in 1932 by the Mathis Yacht Building Co. of Camden, New Jersey, as the yacht Alamo as confirmed by the oval shipbuilder's plate affixed in the upper access portion of its engine room. Alamo was designed by Tams, Incorporated for William F. Ladd with a cruising radius of 4,000 mi (6,400 km) and a fresh water capacity of 5,500 US gal (21,000 L; 4,600 imp gal). A pair of Winton diesel engines of 375 horsepower each and two 15 kW Winton diesel generators provided propulsive and electrical power. A speed of 14.5 knots (16.7 mph; 26.9 km/h) was achieved in trials. The hull construction made extensive use of welding. Before Navy acquisition the yacht, Mathis hull #214, official number 231388, had been named Rellimpa, Ranley, and Ronaele.

The yacht was donated to the U.S. Navy on 3 January 1942, by Eleanor Widener Dixon. It was renamed Alabaster on 13 January 1942 and simultaneously classified a coastal patrol yacht and designated PYc-21. Converted by the Philadelphia Navy Yard for naval service, it was commissioned on 31 January 1942.
