ABSTRACT:
A boat ladder for boarding an inflatable pontoon boat, dinghy or similar small craft of the type having opposed generally parallel gunwales. The ladder has two generally parallel ladder supports, each with a first end bendable across one of the gunwales. Plural and parallel ladder steps extend between the two ladder supports and a strap is coupled at one end to the first end of both of the ladder supports. The strap is dimensioned to extend across the space between the gunwales. A hook extends about the second gunwale for coupling the other end of the strap to the other gunwale, whereby the weight of a person climbing up the ladder is distributed relatively evenly across both the gunwales.
