Final answer:
Boats designed with displacement hulls are made to move through water efficiently by displacing the water aside for smooth and steady navigation, appropriate for long-distance and larger vessels.
Step-by-step explanation:
Boats with displacement hulls move through the water by pushing the water aside and are designed to cut through the water with little propulsion. This design is distinct from a planing hull, which rides on top of the water at high speeds, and multi-hulled boats like catamarans and trimarans, which also have different dynamics in water.
Displacement hulls are efficient at providing steady, smooth travel over water, especially for larger vessels and those designed for long-distance travel, such as the historical caravel ships. The movement of such boats can be affected by forces like the interaction between oars and the water as well as friction, which are significant when considering the propulsion mechanism, such as propellers or sails. The design of hulls plays a crucial role in a ship's maneuverability, speed, and the ability to carry provisions for extended durations at sea.
