A magnetic holder for pulling in and securing a platform and personnel to the hull of a ship to be serviced is disclosed. A lightweight corrosion resistant body member houses a permanent magnet and has an extension for receiving an elongated tool with which the holder is brought in contact with the ship's hull. A flexible resilient line attaches the platform to the holder and allows the platform to be pulled to the hull. Easy removal of the holder is accomplished by applying an external force to the extension creating a turning moment to overcome the magnetic holding force. (Author)
