Which of the following is a characteristic of an overloaded boat?

An overloaded boat typically handles poorly due to the excess weight it carries. This excess load can affect the boat's center of gravity and make it less stable, leading to difficulties in steering and maneuverability. As the boat becomes heavier than its intended capacity, it may also sit lower in the water, increasing the risk of swamping or capsizing, particularly in rough conditions. This degradation in handling can create safety issues for those onboard, impacting not just performance but also the overall safety of the vessel.

In contrast, the other options suggest benefits that do not correspond to an overloaded condition. An overloaded boat does not increase speed; rather, it often results in reduced speed. Fuel efficiency typically diminishes with added weight, and stability is also compromised, making the claim of enhanced stability incorrect.
