Cape Leeuwin is the most south-westerly mainland point of the Australian Continent, in the state of Western Australia. A few small islands and rocks, the St Alouarn Islands, extend further to the south. The nearest settlement, north of the cape, is Augusta. South-east of Cape Leeuwin, the coast of Western Australia goes much further south. Located on headland of the cape is the Cape Leeuwin Lighthouse and the buildings that were used by the lighthouse keepers. In Australia, the Cape is considered the point where the Indian Ocean meets the Southern Ocean; however most other nations and bodies consider the Southern Ocean to only exist south of 60°S.

A sextant is an instrument for determining the angle between the horizon and a celestial body such as the Sun, the Moon, or a star, used in celestial navigation to determine latitude and longitude. The device consists of an arc of a circle, marked off in degrees, and a movable radial arm pivoted at the centre of the circle. A telescope, mounted rigidly to the framework, is lined up with the horizon. The radial arm, on which a mirror is mounted, is moved until the star is reflected into a half-silvered mirror in line with the telescope and appears, through the telescope, to coincide with the horizon. The angular distance of the star above the horizon is then read from the graduated arc of the sextant. From this angle and the exact time of day as registered by a chronometer, the latitude can be determined (within a few hundred metres) by means of published tables. (Source Encyclopaedia Britannica)

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed measurement instrument used in meteorology. (Source Wikipedia)

The Aghulas Bank, from Portuguese for Cape Agulhas, Cabo das Agulhas, “Cape of Needles”) is a broad, shallow part of the southern African continental shelf which extends up to 250km (160mi) south of Cape Agulhas before falling steeply to the abyssal plain. It is the ocean region where the warm Indian Ocean and the cold Atlantic Ocean meet. This convergence leads to treacherous sailing conditions, accounting for numerous wrecked ships in the area over the years. However the meeting of the oceans here also fuels the nutrient cycle for marine life, making it one of the best fishing grounds in South Africa. (Source Wikipedia)

The Saint Peter and Saint Paul Rocks (Portuguese Penedos de São Pedro e São Paulo), is an archipelago lying about 685 miles (1,100 km) off the coast of northeastern Brazil, just north of the Equator. Under Brazilian sovereignty, it consists of six large islands, four smaller ones, and several rock tops. It is one of the most important fishing sites of northeastern Brazil, and several migrating species are caught there annually. The islands are unhospitable and uninhabited. A scientific station was established there in 1998. (Source Encyclopaedia Britannica)

Gooseneck (or goose) barnacles (order Pedunculata), also called stalked barnacles or gooseneck barnacles, are filter-feeding crustaceans that live attached to hard surfaces of rocks and flotsam in the ocean intertidal zone. (Source Wikipedia)

Unless the structure of the boat renders them unnecessary (quarter berths, pilot berths with partitions), bunks on a yacht must have lee-cloths to prevent the sleeper falling out due to the motion of the vessel. These are sheets of canvas attached to the open side of the bunk (very few are open all round) and usually tucked under the mattress during the day or when sleeping in harbour. Lengths of rope are attached to the upper corners of the lee-cloth, and fittings are provided above the bunk to which these lines can be tied, holding the cloth in place as a kind of wall across the open side of the bunk.

The Falkland Islands, also called Malvinas Islands or Spanish Islas Malvinas, are an internally self-governing overseas territory of the United Kingdom in the South Atlantic Ocean. It lies about 300 miles (480 km) northeast of the southern tip of South America and a similar distance east of the Strait of Magellan. (Source Encyclopaedia Britannica)

The equatorial trough is a zone of relatively low pressure which lies between the subtropical anticyclones of the two hemispheres. (Source Bureau of Meteorology)

Rolland “Rolly” Tasker AM (21 March 1926– 22 June 2012) was an Australian sailor who won Australia’s first Olympic sailing medal, at the 1956 Olympic Games in Melbourne. From 1969 to 1985 Tasker dominated ocean racing in Western Australia with five sister yachts all called Siska. He won numerous other ocean racing events in his career including taking line honours and first place in the Queen Victoria Cup off Cowes, England. Tasker was inducted into the Western Australian Hall of Champions in 1986 and the Sport Australian Hall of Fame in 1996. He became a Member of the Order of Australia in 2006 for his services to sailing. Sails for Jon Sander’s Parry Endeavour were made by Tasker Sails. (Source Rolly Tasker Sails)
