fairing

Fairing is a structure designed to create a smooth outline and reduce drag, commonly seen on airplanes. In ship design, "fairing" refers to the process of mathematically delineating a hull to produce a smooth shape free from bumps or discontinuities. This is crucial for minimizing resistance as the ship moves through water.12

The shape of a ship's hull is influenced by several factors, including ease of construction, stability, and strength. However, the primary consideration is often the hull's interaction with the water, which determines the resistance the ship encounters. This resistance has components such as friction between the water and hull, energy used to create waves, and energy lost to eddies.3

Naval architects aim to design hull forms that minimize these resistances. This involves using smooth, flowing surfaces and carefully shaping the hull, especially near the water's surface, to reduce wave-making. While minimizing resistance is important, the overall design of a ship also considers other factors like cargo capacity and construction costs.34
