Archimedes ships3/23/2023 As long as the ship design was water-dynamic, the energy source (steam or sail) and material (wood or iron) were all but irrelevant (a metal hull is, in fact, around 70% lighter than a wooden one). The crucial consideration was how much water a ship had to push against as it moved forward. Brunel, an instinctive mathematician, knew that he need not worry about the weight of the ship or its displacement in the water. Robert Howlett (Copyright) Bigger is Betterīrunel was about to blow out of the water the widely-held view that a big iron ship would need so much fuel to push it through the water that it could never hope to cover long distances. The steamships would reach their destination port faster than sailing hips not because of their speed per hour necessarily but because they did not need to tack against a headwind and could take the straightest possible route. The British engineer Isambard Kingdom Brunel had the idea that massively increasing the scale of ships would solve the problem of space and a transatlantic passenger and freight service could be profitably run. With massive holds full of fuel, there was not a lot of space left for passengers, and so most of these early steamships were limited to rivers or close shore work. One of the problems of the early ships powered by steam engines was that they required a prodigious amount of coal and freshwater to run. It was the largest passenger ship in the world at the time and showed that giant metal steamships were faster and more energy-efficient than smaller wooden vessels. The SS Great Britain was a steam-powered ship designed by Isambard Kingdom Brunel (1806-1859) which sailed on its maiden voyage from Liverpool to New York in May 1845.
