Q:HMS Ems was a Dutch schuyt that the Royal Navy captured in 1809. She appears to have had a completely uneventful career; in 1812 and 1813 she was at Yarmouth. She was converted to a water carrier probably in 1813. In December 1815 the Admiralty put three schuyts Patriot Jahde and Ems up for sale at Chatham. All sold in 1815.
