DESCRIPTION OF RED MENT Disclosed in the attached illustrations is a novel design for a pleasure marine craft. Among the novel aspects of the disclosed marine craft is a double- deck configuration comprising an upper exposed deck and a lower, substantially enclosed deck. The exposed upper deck comprises a completely open floor plan design consisting of a single level, substantially flat, deck in which the only permanent protuberance is a console housing the engine controls for the marine craft and, optionally, supports for a roof structure.

As a result of the open floor plan, a passenger on the disclosed pleasure craft will be able to completely ambulate every inch of the upper deck, from bow to stem, ard to port, t requiring the climbing of steps or the avoidance of consoles, closets, walls, ure, cabins or other obstructions typically found on pleasure marine craft.

Another novel aspect of the upper deck is the use of collapsible bulwarks on both sides of the deck. The collapsible bulwarks are hinged at the floor level and collapse outwardly 90 degrees. When in the collapsed position, the bulwarks act as extensions of the deck floor providing a significantly expanded upper deck. The collapsed bulwarks thus become part of the deck and can be used to enhance the visual ence and the available space on the deck.

For safety purposes, the inside (when ) or top (when extended) surfaces of the collapsible bulwarks are equipped with a stowable and/or removable handrail system. When the bulwarks are in their collapsed position, the handrails are removed or stowed and lay hidden and substantially flush with the bulwark: surfaces. Once the bulwarks are extended, the handrails can be alled or deployed or remain stowed depending on the vessel's configuration and sea conditions.

When the vessel is in its navigation configuration with the bulwarks extended, the handrails are deployed to provide additional safety to occupants and to prevent from occupants or objects from accidentally falling overboard.

Once the vessel is at anchor, and sea ions are sufficiently calm, the handrails can he stowed or removed to provide a clear deck. The il system permits for removal of individual handrails so that some portions of the ks remain guarded, while others can be cleared. in addition, the handrail and bulwark system can optionally incorporate an alarm system to advise the vessel's operator that the handrails are in a position deemed unsafe for the anticipated conditions. For example, the alarm would sound if the vessel's s are started with the bulwarks in. the extended position or with the handrails stowed or removed.

The ation of the open floor plan and collapsible bulwarks create an amount of usable, unobstructed space that is usually found only in large s with a fly bridge (also ed to as a flight or flying bridge) without the drawbacks or expense of a much larger vessel.

The lower deck of the disclosed marine craft is comprised of fore and aft sections and is located slightly above the waterline. The fore section is enclosed and located directly below the upper deck. The aft portion is an d extension of the fore portion, forming the stem of the marine craft.

The floor of the lower deck is also ntially flat from bow to stem, with the aft portion g as a "swim deck" for the vessel. Like the upper deck, the aft portion of the lower deck employs collapsible bulwarks which, when deployed, significantly expand the surface area of the swim deck.

The aft and fore portions of the lower deck can optionally be divided by a door, in one embodiment, the door separating the aft and fore portions of the lower deck covets substantially the entire space between the upper and lower decks at the point of convergence between the fore and aft ns of the lower deck- Accordingly, when said door is , a large entrance to the enclosed portion of the lower deck is provided. The enclosed space between the upper and lower decks can be utilized as cabin space for the vessels' occupants or for equipment such as jet skis or similar personal water craft.

Because the upper and lower decks are substantially flat, the overhead clearance available to the enclosed portion of the lower deck is substantially higher that that available to the lower deck of similar dual deck marine vessels.

This icant overhead clearance and large opening of the enclosed portion of the lower deck give the space the feeling and appearance of a large "garage" which can be used to house smaller recreational marine vessels, such as jet skis", wave runners, dinghy s, and the like.

The upper and lower decks are connected by one or more staircases or ladders that can optionally be located on either side of the lower deck's door or within the enclosed portion of the lower deck.

Referring now to FIGS. 1 - 3, shown are renderings of an embodiment of the disclosed marine vessel 100 in the navigation configuration with upper bulwarks 101 and lower ks 102 retracted (, stopped configuration with upper bulwarks 101. and lower bulwarks 102 ed (; and stopped configuration with tipper bulwarks 101 and lower bulwarks 102 extended and upper handrails 103 installed ( FIGS. 4 - 5 provide a rear-oriented view of the same embodiment as FIGS. 1 - 3 in which, again, the upper bulwarks 101 and lower bulwarks 102 are shown in retracted ( and extended ( urations. Also e from this view is staircase 104 leading from swim deck 105 to upper deck 106.

Also clearly visible in this view is garage door 107 which, when opened, reveals the expansive interior "garage" of the lower deck.

Shown in is a rear elevation of the same embodiment of the present invention. For clarity, only the upper retractable bulwarks 101 are shown in the extended position. The upper retractable bulwarks are shown in the retracted position in phantom lines 101*. Also shown is staircase 104 which provides access from the swim deck 105 to the upper deck 106. Garage opening 108 is also shown in this view with the garage door (not visible) opened.

As shown in FIG, 6, upper retractable bulwarks 101 are joined with upper deck 6 by means of a continuous hinge 109 which s through the entire length of the bulwark. The design of the hinge ensures that when the bulwarks 101 are in the extended position, there is no gap, discontinuity or level change between the upper deck 106 and bulwarks 101, thus forming a continuous expanded upper deck which is ideal for entertainment activities. A similar hinge configuration (not shown) is used for the joint between the lower retractable bulwarks 102 and swim deck 105.

Hinge 109 can be manually operated to extend bulwarks 101 and 102, or it may be equipped with an electric motor (not shown) to facilitate automated pushbutton deployment Referring next to FIGS. 7 - 8, shown is a side elevation of the same embodiment of the t invention in which, again, the upper bulwarks 101 and lower ks 102 are shown in retracted ( and ed ( configurations. In FIG 7, LOA = 19120MM OR 63’. In FIG 8, also shown, is optional, able, deck ure 110, and the engine console 111 located on the upper deck 106.

FIG 9 is a side view section of the same embodiment of the present invention in which it can be more clearly seen that the lower deck 105 is substantially flat and continuous and s longitudinally for substantially the entire length of the vessel. This view also illustrates the substantially constant overhead clearence provided by the parallel upper and lower decks 105, 1 6 in the vessel design of the present invention. Also seen in this vie is interior staircase 113 which, in addition to ase 104 connects the upper deck 106 with the lower deck 105. Finally, shown in is roof structure 114 which is supported, by root supports 115. Roof supports 115 and engine console 111 are the only non-removable obstructions t 0 upper deck 106.

Referring next to FIGS. 10 — 11, shown is a plan, view of the same embodiment of the present invention in which, again, the upper bulwarks 101 and. lower bulwarks 102 are shown in retracted () and extended (FIG. I l ) configurations. For clarity of view, roof structure 11.4 is not shown but roof supports 115 and engine console 111 are visible.

Although the ion is illustrated in detail in the accompanying figures and examples and described herein, various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the disclosed designs.
