Final answer:
Large cruisers and sailboats commonly have displacement hulls to enhance their efficiency and ability to navigate through the water effectively. This design allows for better maneuverability and the ability to carry more provisions for longer voyages.
Step-by-step explanation:
Most large cruisers and sailboats have displacement hulls because it allows them to travel more efficiently through the water. Displacement hulls enable larger vessels to move smoothly through the water, slicing through waves rather than planing on top of them, which is typically the case with smaller boats with flat or semi-displacement hulls.
The design of large cruisers and sailboats reflects a progression of maritime engineering that includes historical advancements such as the caravel and the carrack, built for maneuverability, speed, and to carry significant cargo.
Most large cruisers and sailboats have hull shapes because it allows them to travel more efficiently through the water. The hull shape of a ship affects its speed and maneuverability. For example, a narrow and streamlined hull reduces drag and allows the ship to move faster with less resistance from the water.
