A method of stowing a boat is disclosed. The boat may include three hull segments, namely a first hull segment, a second hull segment, and a third hull segment. The third hull segment may form the bow of the boat. The method may include separating the third hull segment from the other hull segments. Thereafter, one of the first hull segment and the second hull segment may be pivoted and inverted over onto the other such that the first hull segment and the second hull segment collectively form a clamshell enclosure. The relative sizing of the first, second, and third hull segments may be such that the third hull segment may be stored within an interior volume of the enclosure.
