What is a disadvantage of a multi hull?

A multi-hull boat, which includes catamarans and trimarans, has unique handling characteristics that differentiate it from conventional mono-hull vessels. One of the primary disadvantages of a multi-hull is that it needs a larger area when turning. This is due to its wide beam and stable design. As the boat turns, the wide stance can make it less maneuverable in confined spaces and require more space to complete a turn effectively compared to narrower hulls.

The larger turning radius is a critical factor for operators to consider, especially in environments with limited water space or obstacles. While multi-hulls can generally achieve higher speeds or provide other benefits such as stability and less draft, the requirement for a larger area during turns can be a significant operational challenge.

The other aspects, such as speed, maintenance, and the need for a flatter water surface, do not pertain to the fundamental turning dynamics that define the inadequacies associated with maneuvering multi-hull boats.
