Ship
In the 4th millennium BC, model ships appeared in Egypt as the earliest historical evidence of watercraft. These artifacts predate written records by centuries yet prove that early societies mastered floating platforms long before they could write their names. The ancient Egyptians built sailboats with remarkable skill during the Old Kingdom period between the 30th and 25th centuries BC. They sailed the Red Sea to reach the myrrh-country according to historian Agatharchides. A wooden vessel known as the Khufu ship lay entombed at the foot of the Great Pyramid around 2500 BC until its discovery in 1954. This intact example demonstrated how perfectly at ease these builders were with constructing large sailing vessels.
Across the globe in Mesopotamia, model ships dated back to the same era while inscriptions from Lagash kings mentioned ships in connection to maritime trade and naval warfare around 2500, 2350 BC. Austronesian peoples originated in what is now Taiwan and took part in a massive expansion across half the globe using distinctive technology including catamarans and outriggers. Their crab claw sails enabled them to sail for vast distances in open ocean starting some time before 2000 BC. By the 2nd century AD people from the Indonesian archipelago made large ships measuring over 50 meters long standing 4, 7 meters out of water. These kunlun bo carried 600, 1000 people and 250, 1000 tons of cargo with four to seven masts able to sail against the wind due to tanja sails.
Northern Europe clinker construction predominated until the late 13th or early 14th century when hull planks fastened together in an overlapping manner defined the shell first technique. Reinforcing ribs fitted after the planks allowed these Northern European ships to carry single masts setting square sails steered by rudders hung on the sternpost. Mediterranean shipbuilding traditions used carvel construction where hull planking fitted to frames determined the shape frame led rather than plank led. These round ships rigged with lateen sails on one or more masts steered with side rudders merged with Northern designs during the 12th and 13th centuries.
Cogs traveled to the Mediterranean carrying square sails on mainmasts but lateen sails on mizzen masts replacing side rudders with sternpost hung rudders. By late 1430s instances of carvel ships appeared in Northern Europe increasing over the rest of the century creating full-rigged ships three-masted vessels with square-rigged foremast and mainmast plus lateen sail on mizzen. This hybridization provided most ships used in the Age of Discovery able to carry sufficient stores for long voyages with rig suited to open ocean. The transition from clinker to carvel construction facilitated artillery use at sea since internal framing could accommodate gun weight making it easier to fit gunports in carvel hulls.
Rome consumed about 150,000 tons of Egyptian grain each year over the first three centuries AD relying entirely on sailing and human powered ships for delivery. It cost less for a Roman Empire sailing ship to carry grain the length of the Mediterranean than moving the same amount 15 miles by road. During the 15th century China's Ming dynasty assembled one of largest and most powerful naval fleets for diplomatic power projection voyages of Zheng He. In Japan during Sengoku era from 15th to 17th century coastal fleets fought feudal supremacy struggles including hundreds of boats like atakebune.
The empire of Majapahit used large jong ships built in northern Java transporting troops overseas carrying 100, 2000 tons cargo and 50, 1000 people measuring 28.99, 88.56 meters long. About four hundred largest junks deployed when Majapahit attacked Pasai in 1350 alongside many barges and galleys. By 2019 world fleet included 51,684 commercial vessels gross tonnage more than 1,000 tons totaling 1.96 billion tons carrying 11 billion tons cargo in 2018 growing 2.7% over previous year. Such ships carried dry bulk 43 percent oil tankers 28 percent container ships 14 percent demonstrating how transport became responsible for largest portion world commerce.
In 2016 more than 49,000 merchant ships totaling almost 1.8 billion deadweight tons categorized oil tankers 28 percent bulk carriers 43 percent container ships 13 percent. By 2023 number ships globally grew 3.4 percent new ships increasingly built alternative fuel capability increase sustainability reduce carbon emissions including LNG LPG methanol biofuel ammonia hydrogen among others. Wind power received renewed interest potential mitigate greenhouse gas emissions as of 2024.
