Built in 1914 by Fleming and Ferguson in Paisley Scotland as Sir William Matthews for the Ceylon Government, she was a twin screwed steam bucket dredge. She was purchased from the Western Australian Government by the Melbourne Harbour Trust on 10 October 1941. After an extensive overhaul, the vessel was renamed the George Kermode and commenced operation in Victorian waters on 22 June 1942. The George Kermode was scuttled by the Department of Conservation, Forests and Land off Phillip Island on the 1 April 1976 as part of an artificial reef program. This vessel was used to dredge the Port Phillip channels from 1942 and is of cultural significance to Queenscliffe.Binnacle compass from the 'George Kermode'Compass No. 3127N Sestrel Type 89098bucket dredge, port phillip, melbourne harbour trust

Kelvin Company History: The origins of the company lie in the highly successful, if strictly informal, the relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, who was an optical instrument maker in Glasgow in 1850. He was involved in supplying and mending apparatus for Thomson's university laboratory and working with him on experimental constructions. White was actually declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson's laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson's design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company). Thomson, who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death in 1884, raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd . Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd . Hughes Company History: Henry Hughes & Sons was founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as Henry Hughes & Sons Ltd in 1903. In 1923, the company produced its first recording echo sounder and in 1935, a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing Marine Instruments Ltd. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd., Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military use. This model compass is a good example of the commercial type of instruments made by Kelvin & Hughes after the world war 2, it was made in numbers for use on various types of shipping after the second world war and is not particularly rare or significant for it's type. Also it was made no earlier than 1947 as the firms of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd who took over from Smith & Sons were not amalgamated until 1947. Given that Smith and Sons is engraved on the compass with Kelvin & Hughes it can be assumed that this compass was made during the company's transitional period to Kelvin & Hughes.Compass, marine or ship's card compass, gimble mounted, with inscriptions.

The nautical compass is used for determining directions, using a free moving magnetised needle, indicating north and south. This is a medium sized compass and was suitable for mounting in a fixed brass binnacle or a portable wooden box. The compass fluid was typically lamp oil, or a mixture of alcohol and water. This compass, based on its pattern, was probably manufactured around the 1930s. The compass’s maker, Bergen Nautik, was a 20th Century compass manufacturer, making compasses from the 1900s but no longer in business.The factory was located in Hordaland County, Bergen, on the west coast of Norway. This compass is not a very significant marine item as it was made in the 20th century. Examples of the same compass that have been salvaged can be purchased today mounted either in a wooden box or a brass pedestal.Compass; marine or ship's compass, brass, gimbal mounting, in blue metal casing.

This compass was used to determine directions using a free-moving magnetised needle, indicating north and south. W Hartmann was a compass maker located in Hamburg Germany some of his compasses are marked “Gehna” and “Nautica”. There is no information available regards W Hartmann, his successor in the business was “Georg Hechelmann” a marine instrument maker of which Gehna is an acronym of his name. In 1874 he patented an improved version of “Lord Kelvin Thomson’s” compass design of a paper rose with magnets hung on silk threads. It appears he worked in his shop from around 1878 until probably 1905. The company he founded "Gehna" is today a substantial international marine corporation and is still based in Hamburg. A rare example of an early binnacle and compass probably used on a sailing vessel. It is a significant item not only for it’s rarity but also because it demonstrates the progress of marine navigational instrument development in the late 19th century. The item was made by an early pioneer and innovator of marine navigation and instrument making. Compass and Housing; the brass housing, with side light box, insides a fluid dampening gimble compass.

This large compass is well made. It is now pitted and scratched, indication much use. Compasses were used to measure and mark out the head of the barrel by coopers. Very large compasses were used by block, spar and pump makers to help shave off angles left by axes and other tools on mast sides. Also they were used by blacksmiths in their work draftsmen, carpenters, engineers and navigators.This compass is an example of a drawing instrument that could have been used in the 19th and early 20th century by coopers and blacksmiths as well as navigators and ship smiths.Compass; large metal compass, 90-degree angle, two pointed arms hinged at the top.
