The defining feature of a multihull vessel lies in its use of two parallel hulls, rather than a single one. This configuration offers inherent stability, derived from the wide beam created by the separation of the hulls. An example is the reduced heel angle experienced during sailing, improving comfort and efficiency.
This design choice provides advantages in terms of speed and fuel efficiency. The reduced wetted surface area, compared to a monohull of similar displacement, translates to less drag. Historically, this concept has been utilized in various forms across different cultures, evolving into the modern recreational and commercial vessels seen today. The design supports increased payload capacity and spacious interior accommodations.
