Bathing and rescue ladder one end of which is mounted on or near the gunwale (56) or upper end of the transom of a boat and may be pivoted around an axis that is parallel to the gunwale or the upper end of the transom, so that the ladder can be swung at least between a position where it hangs more or less perpendicularly down into the water and a position where the free end of the ladder floats on or near the water surface, and the said free end of which is provided with one or more flotation devices, which in a passive state lacks or lack buoyancy but, when the ladder hangs more or less perpendicularly into the water, can be activated and thereby imparted sufficient buoyancy to lift a person that stands on or holds himself close to the ladder and keep the free end of the ladder floating at or near the water surface even when a person lies on the ladder.
