Sydney Harbour Anti-submarine Boom Net
The Sydney Harbour anti-submarine boom net was an anti-torpedo and submarine defence net that was in Sydney Harbour during World War II. It spanned the entire width of the harbour from Laing Point (formerly known as Green Point), Watsons Bay to Georges Head, on the northern side of Sydney Harbour. The boom formed part of the Sydney Harbour defences which also included artillery batteries and patrol boats. History Construction of the boom commenced in January 1942 and the boom and gates were fully operational by August 1942. For over three years, entry to Sydney Harbour was restricted by the boom net. All vessels including ships, ferries and fishing boats gained access to the harbour via one of three gates in the anti-torpedo and anti–submarine boom which spanned the harbour from Green Point to Georges Head. On the night of 31 May 1942, three Japanese midget submarines entered the harbour in what became known as the Battle of Sydney Harbour (often referred to as the Attack ...

HMAS Sea Mist
HMAS ''Seamist'' (10) (Note: her commissioned name was HMAS ''Seamist, not Sea Mist as recorded on some Navy websites'') was formerly a Sydney-based luxury motor cruiser, commissioned as a channel patrol boat into and operated by the Royal Australian Navy (RAN) during World War II. She was one of thirteen similar vessels, known to Sydney siders as the 'Hollywood Fleet'. ''Sea Mist'' as she was previously named, was and still 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 subsequently purchased by Hope Bartlett before she was requisitioned by the Navy. ''Sea Mist'' was requisitioned on 17 June 1941, and commissioned by the RAN on 21 July 1941 as HMAS ''Seamist'', (An earlier ''Sea Mist,'' previously owned by the Gale's was also acquired by the ...

Military History Of Sydney During World War II
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military History Of Australia
The military history of Australia spans the nation's 230-year modern history, from the early Australian frontier wars between Aboriginals and Europeans to the ongoing conflicts in Iraq and Afghanistan in the early 21st century. Although this history is short when compared to that of many other nations, Australia has been involved in numerous conflicts and wars, and war and military service have been significant influences on Australian society and national identity, including the Anzac spirit. The relationship between war and Australian society has also been shaped by the enduring themes of Australian strategic culture and its unique security dilemma. The six British colonies in Australia participated in some of Britain's wars of the 19th century. In the early 20th century, as a federated dominion and later as an independent nation, Australia fought in the First World War and Second World War, as well as in the wars in Korea, Malaya, Borneo and Vietnam during the Cold War.

Anti-submarine Boom (Lake Macquarie WWII)
The Lake Macquarie anti-submarine boom was a submarine and small boat defence boom located at the entrance to Lake Macquarie, New South Wales, Australia during World War II. It spanned the entire width of the lake channel between Grannies Pool, Blacksmiths and Lucy's Wall, Swansea Heads. It was built to protect the large flying boat base, RAAF Rathmines at Rathmines and as part of southern perimeter defence of Fortress Newcastle. The boom was constructed with a series of poles embedded within the lake channel supported by a net of steel cables. A gap in the boom could be raised with the aid of winches. A pill box and machine gun emplacement were constructed at the Blacksmiths (northern) end of the boom. Trenches zigzagged between Swansea Heads and Caves Beach on the southern side.

Buoy
A buoy () is a floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with ocean currents. Types Navigational buoys * Race course marker buoys are used for buoy racing, the most prevalent form of yacht racing and power boat racing. They delimit the course and must be passed to a specified side. They are also used in underwater orienteering competitions. * Emergency wreck buoys provide a clear and unambiguous means of temporarily marking new wrecks, typically for the first 24–72 hours. They are coloured in an equal number of blue and yellow vertical stripes and fitted with an alternating blue and yellow flashing light. They were implemented following collisions in the Dover Strait in 2002 when vessels struck the new wreck of the . * Ice marking buoys mark holes in frozen lakes and rivers so snowmobiles do not drive over the holes. * Large Navigational Buoys (LNB, or Lanby buoys) are automatic buoys over 10 m high equipped with ...

HMAS Kuramia
''Kuramia'' was a "Sydney K-class ferries, K-class" ferry on Sydney Harbour. Commissioned in 1914, the timber-Hull (watercraft), hulled steamer was built for Sydney Ferries Limited during the early twentieth boom in cross-harbour ferry travel. At 353 tons, she was the largest wooden ferry on Sydney Harbour. She was a typical example of the "K class"; a group of double-deck, double-ended, Steam engine#Multiple expansion engines, steam-powered propeller, screw ferries. ''Kuramia'' was built for the short but busy cross-harbour route between Circular Quay and Milsons Point, New South Wales, Milsons Point. Made redundant by the 1932 opening of the Sydney Harbour Bridge, the Royal Australian Navy converted her to a Net laying ship, boom defence vessel. ''Kuramia'' followed Sydney Ferries Limited's tradition of naming their vessels after Australian Indigenous words starting with "K". ''Kuramia'' was reported to have been named after a village on the Sydney–Perth rail corridor, Tran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tug Boat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness c ...

Dolphin (structure)
A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids. Structure Dolphins typically consist of a number of piles driven into the seabed or riverbed, and connected above the water level to provide a platform or fixing point. The piles can be untreated or pressure treated timber piles, or steel or reinforced concrete piles. Smaller dolphins can have the piles drawn together with wire rope, but larger dolphins are typically fixed using a reinforced concrete capping or a structural steel frame. Access to a dolphin may be via a pedestrian bridge, particularly in the case of mooring dolphins, but is often by boat. Use As mooring point Dolphins are usually installed to provide a fixed structure when it would be impractical to extend the shore to provide a dry- ...

HMAS Kuttabul (ship)
HMAS ''Kuttabul'', formerly ''SS Kuttabul'', was a Royal Australian Navy depot ship, converted from a Sydney Ferries Limited ferry. ''Kuttabul'' and her identical sistership, ''Koompartoo'', were the largest and last K-class ferries built. ''Kuttabul'' had the highest passenger carrying capacity of any ferry on Sydney Harbour and was ordered for the crowded Milsons Point to Circular Quay route. During the Japanese midget submarine attack on Sydney Harbour on 31 May 1942, ''Kuttabul'' was sunk, with 21 naval personnel aboard. Design and construction To service the booming population growth on the North Shore prior to the construction of a bridge connection, Sydney Ferries Limited ordered the largest, and what would be the last, " K-class" ferries. They were ''Kuttabul'' and ''Koompartoo'', steam-powered ferries, built in 1922 by the Walsh Island Dockyard and Engineering Works in Newcastle. Similar in size to Manly ferries, they were rated at 448 gross and 201 net register t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
