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 fiberglass pontoon boat, having raised and integrated fiberglass side rails, a flat floor, and a side entry level with the flat floor. Integrated seats are molded in fiberglass. The hull and deck join together by flexing the hull to compensate for opposing draft angles of the hull and deck at the side entry. The deck has a floor and at least one other interior component, and terminates in a deck trim flange. The hull has at least two hollow pontoons and at least two side rails that extend from an outer edge of the pontoons, and the hull terminates in a hull trim flange. When assembled, the hull trim flange operatively engages beneath the deck trim flange to form a unified pontoon boat having a space between the deck and hull and wherein the side rails are integrated as structural parts of the interior component.

An expansion deck system for vessels includes a frame assembly for positioning between a stationary floor of a vessel and a plurality of pontoons of the vessel. The frame assembly including a first side with a first elongated opening, and a second side with a second elongated opening. One or more sliding deck members are telescopically connected to the frame assembly by one or more sliding rails and transition between a retracted position and an extended position. In the retracted position the one or more sliding deck members are positioned between the floor and pontoons of the vessel, and in the extended position the one or more sliding deck members are positioned alongside the frame assembly.

A pontoon boat includes a deck supported by one or more pontoons. A passenger barrier extends upwardly from the deck. The passenger barrier includes a fixed portion and a movable portion. The passenger barrier includes an opaque panel and a one-way transparent panel.

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.

A barrier (1) installed on a generally upright structure, the structure being generally elongate and protruding from a surface to rise to a first height above the surface, wherein: the barrier has a front surface (10), which lies on a first side of the upright structure, and a rear surface (13), which lies either on the same side, or on the opposite side, of the upright structure, the front and rear surfaces being connected to each other; the barrier rises to a second height above the surface, the second height being higher than the first height; and neither of the front and rear surfaces of the barrier significantly protrudes in a direction which is generally perpendicular to the plane of the upright structure than the other of the front and rear surfaces of the barrier.

An obstruction positioning in a recess between an adjacent pair of security bulwarks mounted outside a perimeter railing of a vessel or marine installation is provided. The obstruction comprises a rear end for positioning towards the perimeter railing, a front end for positioning away from the perimeter railing, and a top side, an underside and a pair of opposing lateral cheeks separating the front end from the rear end. The obstruction comprises a connection facility for connecting the obstruction to at least one of the perimeter railing and the adjacent pair of security bulwarks. The top side slopes downwardly from the rear end towards the front end during use of the obstruction between an adjacent pair of security bulwarks, so that a hand of an unauthorized potential boarder placed on the top side of the obstruction will tend to slide off it in a seaward direction.

A dock handrail gate includes a base plate installable on the surface of the dock and a post mounted to the base plate perpendicular to the base plate. The handrail also has a rail that attaches to the top portion of the post and extends horizontally and inclines downwardly at an angle inwardly towards the post and further attaches to the bottom portion of the post. The handrail may also have an inner tube that includes an inner sleeve to allow the post and the rail to be lifted and rotated to lock into one or more positions.
