An apparatus with two configurations: a deployed configuration forming a watercraft that floats in water and a folded configuration that allows for transport of the apparatus. The apparatus includes multiple modules. One module is a planar sheet of corrugated material with a plurality of joints that allow the sheet to assume the shape of a hull when in the deployed configuration and to assume a box-shape when in the folded configuration. Another module is a paddle assembly that is releaseably connected to a pair of sidewalls when the sheet is in the deployed configuration. The paddle assembly is foldable such that it fits within the box-shape when the sheet is in the folded configuration. The planar sheet is foldable around a plurality of joints or hinges that are configured to fold two ways, thereby allowing the sheet to assume the two configurations.
