Abstract
Water craft or amphibious vehicle includes a hull 12 fitted with at least one elongate longitudinal keel; which may be extruded from rubber. The keel has at least one mounting formation, to engage with channel formation. The keel may be mounted directly into hull; alternatively, at least one mounting structure may comprise an extrusion; mounted into a channel in the hull. The keel may be flexible to resist damage if grounded; but is laterally stiff to aid handling on water. The keel may be slid into place longitudinally; and may be finished with a rubber end piece, protected by a further metal end piece. Both end pieces may be detachable. Keel may be foam filled; or may be inflated with fluid to alter its cross section.
