This representative example demonstrates a mariner’s astrolabe. Historical examples are rare. There are less than one hundred known to exist and most of these have been recovered from shipwrecks, many from Spanish and Portuguese vessels. An astrolabe is a measuring device once used to navigate the seas by observing the sun and stars to measure their altitude. The measurement of altitude could then be used to calculate the ship’s latitude but at that time in history there was no means of measuring longitude. The body of the navigational astrolabe was cast brass and much heavier, and less complicated than the variety used on land. The heavier weight and cut-away shape reduced the effect of the wind and waves when trying to use it at sea. A mariner’s astrolabe or ‘star finder’ is a simplified version than that used by Arabic astronomers to find the altitude of the sun and stars above the horizon, and time of the sunrise and sunset. It is a forerunner to the quadrant, octant and sextant and was popular for about 200 years over the 1500s and 1600s to find the latitude of a ship at sea. The user held the astrolabe at eye level and, usually with assistance, aligned the stars through the two small sights (pinnules), then read the altitude indicated by the pointer on the arm. It could also be used to sight the sun by holding it lower down, aiming it at the sun, and adjusting it until the sun shone through both pinnules. This astrolabe is an example used to demonstrate the mariner’s astrolabe, which was navigational tool of the 1500s and 1600s, in the time before longitude was able to be determined. It is a forerunner to modern navigation technology. Mariner’s astrolabe – a representative example. A gold painted, disc shaped object with cut outs and revolving arm in centre.

Dividers are used by navigators to measure the distance between two points on a map or chart. Each point of the divider is places on a map point, then the distance between the points of the divider is measured against the scale of the chart or map. This helps determine the ship's path of travel, the distance travelled and the current location.Not very significant as not associated with any historical event or person, same pattern of dividers is available today from many retail outlets.

An aeronautical chart is a map designed to assist in navigation of aircraft. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. World aeronautical charts have a scale of 1:1,000,000 and cover relatively large areas. Orbost Aero Club began in 1969 with Basil Dowie as Chair, David Nixon as Secretary/Treasurer. The group went into recess from 1977-1991 closing in 1997. The mid 1960s were boom years in flying training in Australia and the number of Aero Clubs grew rapidly. The Club played a significant role in the establishment of the small airport at Marlo and in the ongoing operation and development of the airport over the years particularly for patient transfer by aerial ambulance.

The flywheel possibly belongs to a Walker's Cherub Mark III Ship-log taffrail, how the flywheel operates is a metal loop of the recording log would have been connected to the flywheel, so you could see if it was spinning properly. After the flywheel, is the rotor that was towed behind the ship and the revolutions of the rotor would register on the indicator, thus measuring the distance the vessel had travelled. Thomas Ferdinand Walker (1837–1921) first patented the Cherub log in 1878. It was one of the first logs in which the recorder was placed onboard a ship rather than being incorporated as part of the rotor. The Cherub Mark III series was produced from 1930 it came in two versions a thousand-mile which is quite rare and a five hundred-mile version.This ship log flywheel was invented and made by a significant marine instrument maker and innovator of machinery Thomas Walker. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades to measure the distance travelled at sea updated versions are in use today by mariners.Log Governor (or Fly-wheel) from a Ships Taffrail Log, metal wheel with 6 spokes, hub has rope attached for connecting to ships log.

A Ship's Log looked very similar to a torpedo but was used to measure the speed of a ship. When dragged behind the vessel, movement of water past the propeller caused it to rotate, turning the small needle dials to record the distance and speed travelled. https://museumsvictoria.com.au/immigrationmuseum/resources/journeys-to-australia/Ship's Log Display HeadWalkers Cherub 111 ships lognavigation, speed, knot, chip log, log, thomas walker and son

The ‘Resumatic’ brand, British made, lightweight device comprises a red pulley with attached length of white rope and harness. Information on the item indicates that it was the property of the Department of Transport, Australia. The Commonwealth Lighthouse Service was associated with the Department of Shipping and Transport in 1951 and the Navigational Aids Branch of the Department of Transport in 1972 so the harness may date to this period. The easily operated descent device was used for automatic, controlled descents from overhead structures, such as towers and other buildings and did not require a power source or tools. The user needed to make sure the unit is secured to an anchor point so that the cable could be dropped to the ground. As soon as it was secured the user could put on the support harness, step off the edge and travel down to safety. The device complements a number of other items of rescue equipment held in the wider Parks Victoria lightstation collection which attest to the dangers inherent in lightstation work and necessity for first aid kits, resuscitators, life buoys, life jackets and other devices such as harnesses and pulleys used for moving people. These include a bosun’s chair and harness with pulley, Royal Flying Doctor first aid cabinet, resuscitator kit and case, first aid kit, lifebuoy and cork fragments x 4 all in the Gabo Island collection; a rescue basket, resuscitation kit and case, and pulleys and ropes at Cape Otway; rescue stretcher made of bamboo at Wilsons Promontory; and a rescue anchor at Cape Schanck. The Cape Nelson rescue harness, although unique in the broader lightstation collection, is a relatively common device that is still manufactured more or less the same in England. It has second level contributory significance for offering insights into the various methods used in rescue operations by Victoria’s lightstations.Length of white rope attached to a harness and a red pully device.yes

From Scarborough Maritime Heritage Centre: A Yacht Log was a nautical instrument for measuring a vessel's speed and distance travelled. When navigating a ship it is essential to be able to estimate the boat's speed and distance travelled to determine its position at sea. In times past the only way to measure a ship's speed was to throw a wood log into the water and observe how fast it moved away from the ship. In the 16th century, the log was fastened to a rope knotted at set intervals. The log was thrown over the stern (back) of the vessel and a crew member counted the number of knots that were paid out in a set time. From this they could estimate the speed of the vessel through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. In 1878, Thomas Ferdinand Walker (1837–1921), an engineer in Birmingham, patented a mechanical log in which a recording instrument was attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial recorded the distance travelled. The 'Log' at the Heritage Centre was recovered from a skip in Scarborough and was one of the first artefacts collected by the volunteer group. It is made of brass with a ceramic dial, with the main scale marked from 0 to 100 nautical miles and an inset dial marked from 0 to 10 miles. It has a fixing plate, on which it can turn, with which it would have been attached to the 'taffrail', the rail at the stern of a ship, usually on the starboard side. The Walker’s Excelsior Mark IV instrument was designed for smaller vessels, such as yachts, launches and fishing vessels. Its exact date of manufacture cannot be determined but this design was manufactured in the first half of the 20th century. These mechanical logs have now been superseded by electronic equipment such as GPS navigation instruments.This instrument was made by a significant nautical instrument manufacturer and demonstrates the innovation needed at the time for improved navigation and safety at sea.Timber Box containing an instrument for measuring speed and distance. There is a brass, cased log with a white enamel dial. It also includes a towing cord and cylindrical rotator. The box has paper labelling on the front and also the inside of the lid.
