What is a key disadvantage of multi-hulls?

The key disadvantage of multi-hulls is that they require more space while turning. Multi-hulls, such as catamarans and trimarans, have a wider beam than single-hull boats, which enhances their stability and provides them with excellent buoyancy. However, this increased width results in a larger turning radius compared to monohulls. When navigating in tight spaces or making sharp turns, a multi-hull must account for its broader profile, which means it cannot make turns as sharply or quickly as a narrower single-hulled boat. This characteristic can be challenging in confined waters, docks, or marinas where space is limited and precise maneuverability is crucial.

The other options describe characteristics that either do not apply to multi-hulls or do not represent inherent disadvantages. For instance, multi-hulls are actually known for their stability; they can also be quite maneuverable, although their turning radius might be larger. Lastly, having a shallow draft is generally an advantage, allowing multi-hulls to access shallower waters that other boats might not be able to navigate.
