Which hull type is known for its great stability due to its large beam?

The multi-hull type is known for its great stability attributed to its large beam, which is the width of the vessel. Multi-hull boats, such as catamarans and trimarans, feature two or more hulls that provide a broader base in the water. This expanded width enhances stability and reduces the tendency to tip or roll compared to single-hull designs. As a result, they are often favored for recreational boating and sailing for improved performance in choppy waters.

Other hull types, such as round bottom hulls, keel hulls, and planing hulls, may not possess the same level of stability due to their structural designs. A round bottom hull, for instance, is designed for smooth movement through water but may be more prone to rocking. A keel hull emphasizes directional stability and can enhance speed but does not have the broad beam associated with multi-hull designs. Lastly, planing hulls are built for high speeds and efficiency on the surface of the water, but they don’t have the stability of a wider hull form when at rest or in rough conditions. Overall, the multi-hull design's larger beam is a key factor in its superior stability.
