In boating, what does the term "displacement hull" signify?

The term "displacement hull" refers to a specific type of hull design that is optimized for moving through water at lower speeds. This type of hull displaces water as it moves, allowing it to glide more smoothly and efficiently through the water. Displacement hulls are typically found on larger boats and ships meant for cruising or long-distance travel rather than racing.

These hulls are designed to provide good stability and comfort for passengers while operating at slower speeds, making them ideal for activities like sailing or pleasure cruising. They work by moving water out of the way rather than trying to plane on top of it, which is characteristic of planing hulls designed for higher speeds.

In contrast, designs that focus on high speeds typically utilize planning hulls that rise above the water surface. Hence, displacement hulls are not about speed but about effective movement through the water at lower velocities, making option C the correct interpretation of this term. The distinction between hull types is fundamental in understanding how different boat designs impact performance on the water.
