A mechanism positions a movable part relative to a support, between deployed and retracted configurations, with the movable part distant from the support and flush with the support, respectively. A base is attached to the support and has a central hole. A first positioning device has a first body in the central hole and a first off-centered hole relative to the central hole and a first notched wheel mechanically attached to the first body. A second positioning device has a second body in the first off-centered hole and a second off-centered hole and with a second notched wheel attached to the second body rotating when the second notched wheel is actuated. The two positioning devices are mounted fixed in translation relative to the base and position, along the two directions, an interface member of the movable part mounted in the second off-centered hole and attached to the positioning mechanism.

A bulwark terrace with integrated door is provided; the bulwark terrace may be a portion of a bulwark on a ship or yacht that is hinged so as to be able to fold outwards and downwards and be flush with the deck after doing so, thereby extending the deck surface. The bulwark terrace may also include a door that may open independently of the bulwark terrace to allow boarding of the yacht or ship through the bulwark without deploying the bulwark terrace.

The present invention provides an obstruction (10) for mounting along a perimeter of a vessel or marine installation, wherein the vessel or marine installation comprises a deck (51) having a perimeter railing (20) and an upstanding plate (53) along an edge of the deck. The obstruction has an elongate body comprising a longitudinal groove (12) for receiving a lowermost course of rails (203) of the perimeter railing, and a tongue (14) for overhanging the plate (53) on an outboard or seaward side thereof. The tongue comprises a rear surface (142) intended to face in an inboard direction when the obstruction (10) is mounted along the perimeter of the vessel or marine installation. A separation, s, between the rear surface (142) of the tongue and a centreline (X-X) of the longitudinal groove (12) is between 30 and 300 mm, and the centreline (X-X) of the longitudinal groove (12) and the separation, s, together define a plane which subtends an angle, , of between 90 and 135 degrees to the rear surface of the tongue. With such an obstruction, the upstanding plate (53) can be protected, so that the ability of an unauthorized potential boarder to attach a hook to the plate or to gain a handhold on the top edge of the plate are severely impeded. The invention also provides a perimeter protection system (100) comprising a plurality of such obstructions (10a, 10b), a vessel or marine installation comprising a plurality of such obstructions, and a method of protecting a perimeter of a vessel or marine installation using a plurality of such obstructions.

The invention relates to a telescopic dock system, said system comprising: dock surface; at least two posts; a knob; at least one telescopic spindles; and at least one railing. The dock system with telescopic spindles which can be used to stow down the railing by turning a knob is disclosed. The system can allow a person to protect kids, pets from falling in the water. The system is a convenient way to improve safety without restricting fun on the docks.

A security device comprising: a plate (20) having an upper portion (21) and a lower portion (22), wherein the upper portion and the lower portion are parallel and off-set; a bulbous barrier (30), wherein the upper portion of the plate and the barrier form a slot (50) therebetween, and the barrier extends in a direction perpendicular to the upper portion of the plane of the plate and away from the slot.

A bulwark terrace with integrated door is provided; the bulwark terrace may be a portion of a bulwark on a ship or yacht that is hinged so as to be able to fold outwards and downwards and be flush with the deck after doing so, thereby extending the deck surface. The bulwark terrace may also include a door that may open independently of the bulwark terrace to allow boarding of the yacht or ship through the bulwark without deploying the bulwark terrace.

In one aspect, the present invention provides a security bulwark for mounting outside a perimeter railing of a vessel or marine installation. The bulwark has a front face comprising a projecting mound. The mound has an underside which provides the bulwark with an overhang. The mound is also convex in a direction of the breadth of the bulwark. The invention also provides a perimeter protection system comprising a plurality of such security bulwarks arranged side-by-side and adjacent to each other. Finally, the invention further provides a method of protecting a perimeter of a vessel or marine installation. The method comprises positioning a plurality of security bulwarks side-by-side and adjacent to each other along a perimeter railing of a vessel or marine installation, attaching some of the plurality of security bulwarks to the railing, and connecting remaining ones of the plurality of security bulwarks which are not attached to the railing to ones of the plurality of security bulwarks which are attached to the railing. Thus even if a security bulwark cannot be mounted directly to the perimeter railing, for example because of a gap in the railing or an obstruction in the way of the railing, the bulwark can still be positioned in the same location outside the railing and securely mounted in that location by being connected to an adjacent security bulwark which can be mounted to the perimeter railing.

An outboard motor boat is provided with a hull, a deck, at least one outboard motor and a bulwark. The hull includes a rear portion. The deck is provided on the hull. The at least one outboard motor is mounted to the rear portion of the hull. The bulwark is provided on the deck. The deck includes an aft deck in the rear of the deck. The aft deck includes a first part disposed forward of the outboard motor and a second part extending rearward with respect to the first part in a fore-to-aft direction. The first part is at least partially disposed in a non-overlapping location with respect to the outboard motor and the bulwark as viewed from a side view of the outboard motor boat. The second part extends along a lateral portion of the outboard motor.

A bulwark terrace with integrated door is provided; the bulwark terrace may be a portion of a bulwark on a ship or yacht that is hinged so as to be able to fold outwards and downwards and be flush with the deck after doing so, thereby extending the deck surface. The bulwark terrace may also include a door that may open independently of the bulwark terrace to allow boarding of the yacht or ship through the bulwark without deploying the bulwark terrace.

Security barrier comprising: a substantially planar support element (2) having top and bottom edges, wherein respective top and bottom first attachment sites are formed at the top and bottom edges; and a bulbous barrier element (9), which is separate from the support element, having top and a bottom edges and respective top and bottom second attachment sites formed at the top and bottom edges, with a curved protruding section extending between the top and bottom edges, the protruding section extending away from the plane containing the top and bottom edges, wherein the support element and the barrier element are releasably connected to each other by way of the first and second top and bottom attachment sites, so that the support element and barrier element define an internal space therebetween which receives a horizontal rail, and wherein the security barrier may rest on the rail, a vertical plane being defined between the rail and the surface, so that the rail lies at or near the top edge of the support element and of the barrier element, the support element extends close to the vertical plane, and the protruding section protrudes outwardly from the vertical plane.
