Leopoldus Primus
 The Leopoldus Primus also called Leopold I was the first convoy ship commissioned to protect the free city of Hamburg. She was designed for use against piracy on the trade routes to Spain Portugal and West Africa and to accompany whalers to Greenland. Named in honor of the Roman Emperor Leopold I she was put into service in 1668 and scrapped in 1705 after 34 major missions. She was probably identical with the Wapen von Hamburg which went into service shortly after her.
