What are examples of Hull structures?

Hull structures refer to the primary body of a ship or boat that provides buoyancy and strength. Examples include the monohull, which has a single hull design, commonly seen in sailboats and cargo ships; the catamaran, featuring two parallel hulls for increased stability and space; and the trimaran, which has three hulls for enhanced speed and stability. Additionally, specialized hull designs like the deep-V hull, used in powerboats for better performance in rough waters, also exemplify hull structures.
