Patrol and Training Craft (YP)

Most recent update: May 2, 2011.

The designation YP originally meant a yard patrol craft.  The Navy created its initial fleet of YPs from about sixty Coast Guard boats no longer needed after the end of prohibition.   This fleet grew to about 650 for WWII, mostly by the acquisition and conversion of private yachts and fishing vessels.  After the war, all these boats were sold off and the YP became a training craft, primarily at the U.S. Naval Academy.  The table below is more comprehensive, I think, than any you will find anywhere else, but it still has some gaps.  If anyone can add to it or otherwise improve it, please send your info to timcolton@aol.com
