The invention relates to a boat landing structure suitable for being used in a marine construction, wherein said marine construction comprises, essentially, a concrete shaft intended for being installed anchored at a depth level with respect to the water level, and wherein said boat landing structure comprises two substantially vertical and parallel ribs, integrated in the shaft of the marine construction and projecting out from same, wherein said ribs are made partially or entirely of concrete. Likewise, the space comprised between said ribs houses an access ladder suitable for being used by personnel accessing the marine construction from an operation boat. The invention also relates to a marine construction and a segment comprising the mentioned boat landing structure.

A boarding apparatus for use on a flotation device, in accordance with various embodiments is disclosed herein. The boarding apparatus comprises a stirrup ladder. The boarding apparatus may be integral to a lifeline assembly of the flotation device. The boarding apparatus may be removably coupled to a loop patch of the flotation device. The boarding apparatus may release from the loop patch and become a boarding configuration for the flotation device.

An apparatus for aiding a person to get on and off a boat, the boat step apparatus has two side-rails and a step therebetween. The first side-rail is fixed to the step and the second side-rail is pivotally attached to the step. The apparatus is designed to hang off of the side-rail of a boat and give four stable points of contact along the outer hull side of the boat. The apparatus adjusts fit the shape of a hull of any boat.

The objective of the present invention is to provide an accommodation ladder fixing device, which more firmly and safely fixes, to an exterior wall of a ship, an accommodation ladder temporally provided so as to allow pilots to safely board and disembark the ship. That is, the present invention comprises: a housing (10), which has a fixing plate (13) formed at the rear end thereof to be mounted on the accommodation ladder (100), has a fixing box (11), of which the front side is opened, formed on the fixing plate (13), and has hinge shafts (15) formed at both sides of a through-hole (14) of the fixing box (11); an attachment/detachment means (20), which has a movable block (21) insertively provided so as to be movable forward and rearward to/from the fixing box (11), and a magnetic member (22) attached/detached to/from the exterior wall of a hull (200) and provided at the front end of the movable block (21); and an operating member (30) provided so as to pass through the fixing box (11) and the movable block (21) at the upper part of the housing (10), thereby moving the movable block (21) forward and rearward.

A watercraft is basically provided with a watercraft structure and a grab bar. The watercraft structure includes a platform with a recess at a rear edge of the platform. The grab bar is mounted to the watercraft structure in the recess of the platform. The grab bar has a bar portion with a front edge that is disposed forward of the rear edge of the platform with respect to a front to aft direction of the watercraft.

A watercraft is basically provided with a watercraft structure, a platform mount and a platform. The watercraft structure defines an outer top boat perimeter. The platform mount is provided on the watercraft structure. The platform includes a platform portion and a support portion coupled to the platform mount. The platform portion is disposed below the platform mount while the support portion is coupled to the platform mount in a first deployed position that is outside of the outer top boat perimeter. The platform portion is disposed above the platform mount while the support portion is coupled to the platform mount in a second deployed position that is outside of the outer top boat perimeter.

A deployable platform is disposed at a side of the hull of a marine vessel and is movable between a raised position in which the platform is substantially vertically oriented, and a first lowered position in which the platform is in a horizontal orientation. Further, at least a portion of the platform can be lowered to a second lower position that is below the first lowered position. In the second lowered position the platform will normally be submerged when the vessel is afloat in water. In the raised position the platform forms a portion of the side of the hull and acts to exclude water from entering the vessel.

A movable platform assembly for a boat comprises a base structure adapted to be fixed to the boat, a platform, an articulated system that connects the platform to the base structure, wherein the platform is movable between a raised position which is horizontally adjacent to the base structure, and a lowered position which is horizontally away from the base structure, and a pull-out step ladder comprising an articulated parallelogram structure to which a plurality of steps is hinged, the articulated parallelogram structure being connected to the platform and having an end adapted to be fixed to the boat. In the raised position of the platform the pull-out step ladder is arranged under the platform.

A watercraft including a frame and a folding ladder coupled to the frame. The folding ladder is configured for moving in between a folded position and an unfolded position. The ladder includes a stabilizing portion connected to the frame and defining a stabilizing plane and a first stair portion pivotably connected to the stabilizing portion. The first stair portion pivots relative to the stabilizing portion in a first direction of rotation. The ladder further includes a second stair portion pivotably connected to the first stair portion. The second stair portion pivots relative to the first stair portion in a second direction of rotation which is opposite to the first direction of rotation of the first stair portion such that the ladder selectively folds between the folded position and the unfolded position.
