Sailors have been using nautical maps for centuries. These maps are more than just navigational tools; they are also windows into the history, art, and science of maritime exploration.
Whether you’re a seasoned mariner or simply fascinated by the sea, these lesser-known facts about nautical maps of Australia might pique your interest.
The Oldest Australian Nautical Map Is 255 Years Old
In 1770, Captain James Cook charted the Australian coastline in his HMS Endeavour. This was the first known attempt to map the country. His methods combined scientific methods and accurate observation, resulting in an excellent chart that is still referenced to this day.
The Oldest Western Nautical Map is About 745 Years Old
Drawn on parchment, the Carta Pisana is generally believed to be the oldest surviving Western nautical map and is estimated to have been created in about 1280. This nautical map detailed coastlines, trade routes, ports, and other features throughout the Mediterranean. Although it was considered to be fairly accurate, it lacked any depth markings
Australia Has A Huge Coastline But It’s Not The Biggest
Australia’s coastline stretches about 25,760 km, making it a challenge for cartographers. The coastline has a huge variety of features to map, from the rugged cliffs of the Southern Ocean to the intricate reefs of the northeast.
However, Australia has only the seventh-largest coastline in the world. Canada is by far the largest, with an astonishing 202 080 km of coastline. Norway is second at 103,000 km, followed by Indonesia, Russia, the Philippines, and Japan.
Depths Are Still Measured In Fathoms
While most of the world uses meters or kilometres to measure height and depth, nautical charts still use fathoms. One fathom is equal to about 1.8 m.
Fathoms was developed as a measurement by sailors in antiquity who dropped ropes knotted in 1.8 m intervals into the water to test its depth.
One fathom is approximately the height of a 6 ft tall man or the width of his outstretched arms, which is how the unit of measurement was developed.
Nautical Charts Can Become Quite Valuable
Although many sailors simply think of nautical charts as tools of reference, there is quite a robust market of collectors who will pay a good price for a rare or unique chart. Many older charts are seen as antique works of art, particularly those that were hand-drawn.
However, even modern charts can be valuable if they were produced during historic events, are signed or annotated by renowned sailors, or contain rare printing errors. World War II nautical charts, for example, are highly prized by collectors.
