Abstract
Abstract An accommodation ladder is a portable flight of steps down a ship's side usually suspended parallel to the ship's side, used for boarding the ship from a small pier or boat. These accommodation ladders are usually suspended by cables or ropes from a davit on board the ship. With safety becoming of utmost importance for mariners it is important to limit the amount of swing in an accommodation ladder. The current claims describe a switchable permanent magnetic clamp attached preferably rotatably and at adjustable angle to one end of an adjustable length arm, the other end of which can be fitted to the accommodation ladder. The adjustable arm can be extended to required length and the magnet placed in contact with the ship's hull and turned on, providing a rigid anchor for the steps. Item A tem B Item E Item D Item C Item F
