I was looking around at the CGA site and something caught my attention. Link... http://www.uscga.edu/campus/index.aspx A part of a sentence... The view from campus frequently includes Coast Guard vessels in port, such as the Cutter Eagle, the only tall ship in America's active forces. Another tall ship that is active still in America's Active forces is the U.S. Naval Ship the U.S.S. Constitution.So, there is 2 tall ships active in America's active Forces.
