Abstract: A combination foldable camper/boat/trailer system features flexibility, ease of storage, and ease of assembly. The boat may be tapered so that it forms a more stabilized surface in the water and can prevent inadvertent collapse of the shells from an open position (designated self stabilizing). For additional security, the boat may include a securing element, such as a U-shaped securing element which may span the ends of the shells which abut each other so that the integrity of the water resistant shells is not impaired, a flexible weather resistant covering such as a tent mounted over the boat for use as a camper, may be collapsible and can be stored inside the shells when for instance the shell are in a folded position.
