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 marine vessel has a deck surface having a recessed cavity; a seat module having a seating member, an engagement member, and a hinge that couples the seating member to the engagement member; and a retainer configured to retain the engagement member with respect to the recessed cavity. The seating member is pivotable about the hinge into and between a closed position in which the seating member lies flush with the deck surface and covers the recessed cavity and an open position in which the seating member provides seating for user and the recessed cavity is exposed and provides leg room for the user.

A working deck configured to access offshore well heads, comprising: a barge, transverse beams fixed to an upper surface of the barge, wherein the working deck comprises cantilever beams attachable to the transverse beams, and a work platform positioned on the cantilever beams and movable in a lateral direction of the cantilever beams wherein the transverse beams are oriented perpendicular to a forward direction of the barge and comprise at least one of a track beam and one of a hold-down beam for receiving the cantilever beams, wherein the cantilever beams can be moved along the at least one track beam and the hold down beam to change the position of the cantilever beams relative to the barge, wherein the working deck comprises stiffening elements for stiffening the hold-down beam and to prevent or limit deformation of the hold-down beam.

A vessel with three platformsan outer hull, an inner deck hull and a passenger carriage, having four independent suspension systems there between so as to accommodate for the multi axis movements of the outer hull. This multi axis suspension system spread between the three platforms will offer the passenger carriage stability against the pitch, yaw and roll rotations a vessel makes as it twists and turns going up and down the slope of a wave as well as the heave, sway and surge movements induced by the waves pushing the vessel around and or the ship sliding down the face of a wave.

A foldaway balcony that includes a vertical support, a platform structure tiltably mounted to the vertical support and a barrier structure mounted on the platform structure. The platform structure includes a support structure and a floor structure which are tiltable separately from one another relative to the vertical support. The barrier structure includes barrier elements, hinged at the edge of the platform structure, and tiltable between a stowed position in which they lie inside the support structure, and a deployed position, in which they stand up relative to the support structure. A barrier element, connected to a distal side of the edge of the platform structure includes a first and a second pair of stanchions hinged to the distal side, a first and a second rod which interconnect the upper ends of the stanchions, and a handrail with parallel guides, in which are housed the first and the second rods.

An expandable flooring system for a pontoon boat includes a center floor and at least one outer floor. The outer floor is configured to hinge upwards about an edge of the center floor. At least one outrigger is extendable from a corresponding slide track under the center floor. The outrigger is configured to slide under the center floor when the outer floor is hinged upward, and slide out from the center floor for supporting the outer floor when it is hinged down and next to the center floor. A railing system surrounds the periphery of the flooring system and is secured together for providing rigidity to the flooring system.

An elevation system includes deck units each including a frame, a movable deck coupled to the frame to be movable in a vertical direction, a sliding unit coupled to the frame to be movable in a horizontal direction, and elevation wires connected to the movable deck and the sliding unit via a direction changing sheave at the frame, a first sheave at each of the deck units and fixed to the frame, a second sheave at each of the deck units and coupled to the sliding unit to adjust a distance between the first sheave and the second sheave, a drive wire extending through the deck units and simultaneously wound around the first sheave and the second sheave of each of the deck units to deliver a driving force to the sliding unit, and a driver pulling the drive wire to cause the sliding unit to be slidably moved.
