What advantage does a multi-hull have compared to a single hull?

A multi-hull boat is designed with two or more hulls, which provides increased stability primarily due to its wider beam. This wider design dramatically enhances the boat's resistance to capsizing, especially in rough waters, making it suitable for various conditions. The stability is beneficial for both recreational and competitive boating as it allows for a smoother ride and reduces the tendency to heel (lean) to one side.

The wider beam also contributes to a more comfortable experience for passengers, as it minimizes the pitching and rolling that can occur with a narrower, single-hull vessel. Therefore, the inherent design features of multi-hull boats make them preferable for many boaters who prioritize stability on the water.

In contrast, while greater speed and fuel efficiency are occasionally associated with multi-hulls, they are not universal advantages. Additionally, multi-hulls often tend to be more expensive to manufacture due to their complex designs and the additional materials required for construction, which contrasts with the idea of lower manufacturing costs.
