Glamorganbrook The 805 ton steamer Glamorganbrook ex Empire Worthtown, sank in the early hours of October 11 1946 after springing a leak in her No2 hold. Just refitted, this old veteran of the Dunkirk evacuations, developed a slight list to port shortly after leaving Blyth on route to the Isle of Wight with coal, and later when she as radioed "... making water fast and proceeding full speed to Robin Hood's Bay..." rescue services were alerted and later the vessel reported that she was "...becoming unmanageable and heading for Scarborough..." Local lifeboats were launched immediately and it was several hours before the survivors were found in the ships lifeboat. Glamorganbrook had sank in 30 mins after the last distress call, and with the tragic loss of her captain, Eric Baker, who had given up his lifebelt to his wife, before giving orders to abandon ship. The crew had only time to launch one boat and this was swept away from the ship with just two men aboard, the rest having to jump into the icy cold sea. The captain, a non-swimmer, was seen floating for a short while but disappeared before he could be rescued. The Glamorganbrook turned over within seven minutes and sank beneath the waves. The Glamorganbrook had an interesting history, having been sunk at Dunkirk during war evacuations, salvaged by the Germans forces and after the war, taken over by the Ministry of War Transport, along with 90 other captured ships, all renamed with the "Empire..." Prefix. The ships were later offered for sale as prizes of war, and the Worthtown went to Messrs Comber Longstaff of London and later to the Willamstown Shipping Company. Details of the vessel were dimensions 199ft long by 31ft beam. Triple expansion engine.

SNA II. The 2294 ton French collier SNA II, ex ME Harper was reported lost in position 54 22 00N 00 22 30W when torpedoed and sunk by a submarine on June 6 1917.
