摘要 A landing apparatus is disclosed for use during the landing or beaching of a boat, a vessel, or the like to protect the keel and hull bottom from injury and abrasion. The apparatus (12) employs an elongated semi-rigid member (20) disposed longitudinal to the bottom surface of the boat. Rigid and resilient upper support blocks (4) are provided on member 2 or and are angled in such a way (2) and spaced in such a way (6) to accept and cradle the keel of a boat and have surface contact with the hull so as to offer complete protection during the beaching of the latter.
