Sea Mist is a 65 ft cruiser built by Lars Halvorsen and Sons and launched on 14 August 1939. Whilst some reports indicate she was built for Oliver Triggs, the founder of Meadow Lea, or for motor racing identity Hope Bartlett, she was in fact built for Mr and Mrs Gale of Potts Point. She was the second Sea Mist for the Gales. She was subsequently purchased by Hope Bartlett before she was requisitioned by the Navy.[1]

Sea Mist was commissioned by the RAN on 21 July 1941 as HMAS Seamist, (The first Sea Mist was also acquired by the RAN and later sold to the USN as Sea Mist) under the command of Sub-Lieutenant John A Doyle RANR(S).[1]

During the Battle of Sydney Harbour (often referred to as the Attack on Sydney Harbour) by the Imperial Japanese Navy on 31 May and 1 June 1942, Seamist, at approx. 5.00am whilst patrolling between Bradleys Head and the boom net, investigated an object in Taylors Bay. On realising it was the conning tower of the midget submarine (M-21), her commender Reg Andrew bought Seamist to the place where the submarine had just submerged and dropped a depth charge. The blast inverted and blew the submarine to the surface. Seamist returned and dropped a second depth charge, so close that Andrew later said he could have stepped on to the inverted hull of the submarine.[1]

The second blast, however, lifted one of Seamist's engines off its mountings and she had to retire. Her sister ships of the Hollywood Fleet, HMAS Steady Hour and HMAS Yarroma, continued the search and on obtaining a 'contact' at approx. 6.40am, dropped further depth charges. Credit for the destruction of the submarine was given to HMAS Steady Hour and HMAS Yarroma, however subsequent investigations identified it was Seamist's decisive attack that caught the submarine and effectively destroyed her.[1]

In March 1944 Seamist was transferred to the Naval Auxiliary Patrol unit of the RAN, and following a refit in Sydney, she was assigned as an Air Sea Rescue vessel for duty at Darwin. On arrival, Seamist was allotted to Melville Bay for air-sea rescue duties, 650 km to the east from where she had just sailed. On 26 February 1945, with Steady Hour and the former three-masted coastal trader Alma Doepel, she departed Darwin for Thursday Island and Townsville for a refit. On 3 March 1945, she was at Melville Bay when Steady Hour was destroyed by fire whilst refueling.[1]

Seamist arrived at Brisbane on 20 May 1945 for her ‘general refit’ and by September, with no further naval commitment for her, she was directed to Sydney. She departed under tow by HMAS Koala and arrived in Sydney on 8 October 1945. She was ‘paid off’ on 9 November 1945 for disposal. Seamist was re-purchased by Hope Bartlett, and was later owned by a succession owners, including the legendary radio broadcaster Jack Davey.

Today (2020) she remains afloat and in use.[1]

HMAS Seamist was awarded Battle Honours, "Pacific 1942" for her role during the Battle of Sydney Harbour.[2][3][1]
