ABSTRACT:
The present invention relates generally to a boarding ladder for use in conjunction with an inflatable boat having an inflated side pontoon and specifically, to an improved boarding ladder including a strap assembly for mounting the ladder to the inflatable boat. The improved boarding ladder includes a rigid ladder portion containing a pair of struts extending from the rigid ladder portion towards the boat. The struts cooperate with a horizontal cross-piece at the top of the ladder portion to mount the boarding ladder in an orientation extending downwardly and outwardly from the side of the boat and prevent the ladder from rotating under the boat when in use.
