A monohull, also known as a single hull, refers to a type of boat or vessel characterized by having a single uninterrupted hull throughout its length. However, synonymous terms can be used to describe this vessel type. One such term is "monocoque", which denotes a structure where the outer skin carries the main structural load. Similarly, the term "single-hull" can be used interchangeably to describe a boat with only one hull. Additionally, the phrase "hull form with a single body" can be an alternative way to refer to a monohull. These synonyms provide different ways to describe and discuss this type of vessel, allowing for greater variation in written works or conversations.
