The YSD designation of this class of floating crane originally applied to a self-propelled seaplane recovery vessel used at Naval air stations. YSD-11, 20, 22, and 23, constructed at the Charlestown Navy Shipyard were of this class. Later the classification was applied to non-self-propelled seaplane wrecking derricks.
