Definitions

• the present invention relates to a cruise ship comprising a hull and at least one superstructure provided with several superimposed bridges.
• It relates more particularly to a vessel of this type, which is equipped with an external lifting platform.
• elevating platforms located inside the ships are known. Their dimensions are limited to the spaces available inside the structure of the boat. Indeed, the presence of spurs, partitions and slices is an unavoidable constraint.
• External lifting platforms are also known. They are piloted from the inside of the side of a ship where they are stored at sea. Their dimensions are limited by the plating door or the opening made in the plating.
• BE 365931 describes a removable freight elevator that can be temporarily adapted to a ship, only opposite its hull, to transfer goods from the dock to the main deck of the ship, and vice versa.

This part is preferably equipped as a dock with mooring bollards (not shown) and "defenses" 22 to absorb energy during the impact of boats against the platform 2.
