A boat 10 comprising a substantially rigid central portion 18 connected by a hinge mechanism 28, 30 to a sponson 14 located laterally outward. The sponson can move between first and second positions, and a locking means 46 can secure the sponson in at least the first position. When in the second position, the sponson is located at least partially within the central portion. The central portion may form an enclosure for the sponson and may comprise GRP, sheet metal and a double-skin configuration with a hollow or filled buoyancy tank between the skins. The hinge mechanism may comprise an elongate, rigid pintle 28 extending along the side of the central portion through a connector 34 with a through-hole. A free end of the connector may affix to the sponson. The locking means may comprise a locking pin (36, Figure 6) parallel to the pintle, wherein the connector has a through-hole (38) that aligns with the locking pin. The sponson may be axially displaceable on the pintle, and locked in the first position by rotating it to the first position, aligning the locking pin with the through-hole, and axially displacing the connector rearwardly.
