HMS Endeavour

The HMS Endeavour was a Royal Navy research vessel that became famous for its scientific exploration.

It was originally built in 1764 as a merchant collier named the Earl of Pembroke. A collier is a ship used to carry coal. It was built by Thomas Fishburn in the port of Whitby, England. Local sailors called this type of sturdy ship a "Whitby Cat." The vessel had a broad, flat bow and a long, box-like body. This flat-bottomed design was very important for its future missions. It allowed the ship to sail in shallow waters. It also meant the ship could be beached for repairs without needing a dry dock.

To prepare for its famous voyage, the Royal Navy purchased the ship in 1768.

The Admiralty spent £2,840 to buy the vessel. They then spent another £2,294 to refit it at Deptford. This refit included adding a third internal deck for cabins and storerooms. The hull was also covered in copper sheathing. This was done to protect the wood from shipworms. The ship was renamed His Majesty's Bark Endeavour. Lieutenant James Cook was chosen to command the expedition. Cook was a naval officer with expertise in mathematics and cartography, which means map-making. He was a practical leader who could handle both science and navigation.

The mission had two main goals. First, the Royal Society wanted to observe the 1769 transit of Venus. A transit occurs when a planet passes in front of the Sun. Second, the Admiralty wanted to find the Terra Australis Incognita. This was a theoretical "unknown southern land" that many people believed existed.

To protect the crew, the ship was equipped with ten 4-pounder cannon and twelve swivel guns. The crew included 94 people, such as scientists, artists, and marines. They even carried livestock like pigs, poultry, and a milking goat to provide fresh food during the long journey.

In August 1768, the Endeavour departed from Plymouth, England. The ship first stopped at the Madeira Islands to gather fresh supplies. After crossing the Atlantic, it reached Rio de Janeiro in November 1768. The journey became much harder when the ship reached Cape Horn. The crew faced violent storms, heavy rain, and massive waves. At one point, the waves were large enough to submerge the bow of the ship. After several failed attempts, the ship finally passed the Cape in January 1769. It then sailed into the Pacific Ocean toward Tahiti.

In Tahiti, the crew successfully observed the transit of Venus on June 3, 1769.

After this scientific success, Cook began exploring the Pacific islands. He surveyed the Society Islands, including Huahine, Bora Bora, and Raiatea. In October 1769, the Endeavour reached New Zealand. This was the first time a European ship had reached those islands since Abel Tasman visited in 1642. The Māori people saw the vessel and thought it might be a giant bird or a floating island. Cook spent six months mapping the coast and discovered that New Zealand was made of two large islands.

The voyage took a dangerous turn in April 1770 near the coast of Australia. The Endeavour became the first European ship to reach the east coast of Australia. While sailing, the ship ran aground on the Great Barrier Reef. This was a near-disaster for the crew. To prevent the ship from sinking, Cook ordered the heavy guns to be thrown overboard to lighten the load.

The ship had to be beached on the Australian mainland for seven weeks to repair the hull. During this time, the crew used pig iron as ballast to keep the ship stable.

After repairs, the ship sailed north and eventually reached Batavia in October 1770. The crew was sworn to secrecy about the new lands they had found. The Endeavour finally returned to England in July 1771 after nearly three years at sea. The ship's life continued in many different ways. It was later used to move troops and timber. In 1778, during the American War of Independence, it was used as a troop transport. Eventually, the ship was scuttled, or intentionally sunk, in a blockade of Narragansett Bay, Rhode Island.

Today, the legacy of the Endeavour is seen all over the world. Many geographic features, such as the Endeavour River and Endeavour Reef, carry its name. Even three different spacecraft were named after the ship. You can find historical relics in museums, including an anchor and six of its original cannons. A full-scale replica of the ship was launched in 1994. It is now located at the Australian National Maritime Museum in Sydney. You can even see the image of the ship on a New Zealand fifty-cent coin.
