Abstract: A two piece combination boat and luggage carrier having essentially identical half-sections and a plurality of removable seats is releasably joined along abutting sides to form a boat. In one embodiment, the halves are pivotally joined by hinges and the bottom of the boat is provided with raised ribs that mate with grooves formed in the bottom of the seats, the top of the seats being adapted to conform to the roof of an automobile, for transporting the luggage carrier. A third central section having inside dimensions greater than the external dimensions of the half-sections is secured between the two half-sections to provide a boat of larger capacity; the third, central section is adapted for nesting over the top of the closed carrier. In another embodiment, each half section is provided with a single male and female member in the abutting end which are adapted to receiving a pair of vertical blades to connect and secure the halves together to form the boat.
