This is MY Shemara
MY Shemara is a motor yacht built in 1938 by John I. Thornycroft & Company to the order of Bernard Docker. Between 1939 and 1946 she served in the Royal Navy as HMS Shemara.
History
The English industrialist Bernard Docker commissioned John I. Thornycroft & Company to build a yacht to his specifications. The yacht was built at Thornycroft's yard at Woolston, Southampton. She was completed in 1938 and christened MY Shemara. MY Shemara was requisitioned by the Royal Navy at the start of the Second World War in 1939 and used as a training vessel for anti-submarine warfare. (See also Madiz, a similar super yacht that saw RN Service in WWII). It was during a training exercise with HMS Shemara that the submarine HMS Untamed was lost with all her crew. Shemara left Royal Navy service in 1946.
