The Engineering Diary

In today’s world, the four main materials used for building boats, when we talk at the level of mass manufacturers, are steel, aluminium, fibre-reinforced plastic (FRP), and polyethylene. Let us speak about each of these in greater detail. Steel Steel is one of the most popular materials used for boats and has consistently been the material of choice for the past century. Its high strength, durability, resistance to abrasion, and relatively low cost are some of the main reasons why steel is widely used in the industry. However, in the wake of the development of new composite materials, better and cheaper alternatives are being used for manufacturing boats of equal size and strength but considerably lesser weight. This has reduced the importance of steel in boat building to an extent, although it is still used extensively for larger ships. From the point of view of sustainability, steel has a practically airtight production process that produces minimal constructional waste. In addition
