发明名称 Marine bow hand rail mount removable ladder
摘要 The first Marine Bow Hand Rail Mount Removable Ladder. You simply screw the permanent mount to the hand rail in the front (bow) of the boat. Because of my unique new tongue and groove design you can easily and safely slide on the Removable Ladder to exit and enter the front (bow) and simply slide off the Removable Ladder for easy storage on board your vessel.
