A dugout canoe or simply dugout is a boat made from a hollowed-out tree. Other names for this type of boat are logboat and monoxylon. Monoxylon (μονόξυλον) is Greek – mono- (single) + ξύλον xylon (tree) – and is mostly used in classic Greek texts. In German, they are called Einbaum. Some, but not all, pirogues are also constructed in this manner.

A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size, shape, cargo or passenger capacity, or its ability to carry boats.
