发明名称 Boat ladder
摘要 A Boat Ladder is provided which can be in the form of a complete ladder or a kit for mounting a ladder on a boat. The ladder preferably includes two or more ladder sections which can be readily connected and disassembled and easily stowed. Two mounting brackets are designed for use on a variety of gunwhales of boats. The lower section of the ladder has two threaded mounting pins which are adjustably held in the brackets to level the ladder and the pins can be easily separated from the mounting brackets when the ladder is not in use. The mounting pins are also pivoted so as to be swung out of the way along the rails of the ladder, when not in use.
