Which of the following is a characteristic of a multi hull?

A multi-hull boat is characterized primarily by its wider beam, which contributes to its stability on the water. The design typically features two or more hulls that provide a broader platform compared to single-hull boats. This increased width helps to distribute the boat's weight more evenly, making it less likely to capsize in rough conditions and providing a smoother ride in choppy waters. The stability offered by multi-hulls is one of their most significant advantages, particularly for activities like sailing and recreational boating where comfort and safety are important.

The other characteristics mentioned in the other choices do not accurately describe multi-hulls in the same way. For example, while some multi-hulls may require less power compared to traditional hulls due to reduced resistance, this is not universally true for all multi-hulls. The speed advantage of a multi-hull can also depend on various factors such as design and wind conditions, rather than being outright faster than all flat bottom hulls. Additionally, multi-hulls are not specifically better suited for shallow waters, as their wider beam and design can sometimes make navigating in narrow or shallow areas more challenging.
