Abstract: The roof scupper overflow with sensor cooperatively engages and replaces a conventional roof opening through a wall or in a corner to prevent trash from reaching and clogging the conventional roof basket and drain. Accumulating trash builds up on the screen of the roof scupper overflow causing a foam float or buoy connected to a trash tray to rise permitting water to run under the trash trap at roof level. The trash tray is retained to a base with magnets. When the water reaches a predetermined level, the foam buoy rises pulling the trash tray away from the base allowing water to flow to the conventional roof drain basket and activating a magnet switch sending a signal to overflow sensor and a control module connected to WIFI service.

Abstract: A gutter drain is used in connection with a gutter around a hatch mounted in an opening of a boat deck. The gutter drain has a generally U-shaped saddle. The saddle has a pair of opposed side portions extending upward from a bottom portion. The saddle outer surface conforms closely to the gutter inside surface. A circular mounting sleeve is attached to the saddle, and has a plurality of flexible annular rings to mount the gutter drain. A circular nozzle is attached to the mounting sleeve by an elbow having an angle greater than 90°, and has an annular ridge to retain a drain tube. The gutter drain is driven downward into a gutter-mounting hole by a hammer blow, until the saddle is seated in the gutter. The annular rings deflect resiliently upward and are biased outward against the mounting hole, to hold the gutter drain securely in place, and seal against leakage. The saddle side portions are biased outward, and press against the gutter sidewalls to further seal the gutter drain.

Abstract: A sit-on-top kayak hull having an elevated void in the area between the normal seated position of a paddlers legs. The elevated void which is formed into the hull of the watercraft and extends there-through to a height above the normal laden waterline generally to a level of the approximate height of the gunwales forms a hole in the craft which is surrounded by walls.

Abstract: A method and apparatus is disclosed for permitting the passage of conduits through the hull of a boat without the creation of additional holes. Briefly, a conduit-accommodating passageway is defined through the boat's scupper which bypasses the check valve that is associated with the scupper to prevent backflow. An annular body having a radially-extending conduit-accommodating passage communicating between its O.D. and its I.D. is positioned with respect to the scupper so that the fluid passing through the scupper and check valve passes through the generally annular body's ID while conduit passing through the radially-extending passage passes through the scupper but bypasses the check valve.

Abstract: An insert for a marine thru-hull fitting. The insert includes an annular body and an outwardly extending lip. The annular body is adapted to fit closely around the throat of the thru-hull fitting so that the insert can be sandwiched between the flange of the fitting and the hull of the vessel. The lip extends outwardly from the bottom of the body to direct liquid flowing down the fitting away from the hull of the vessel.

Abstract: A drip control marine fitting for passage of liquid through an opening in the hull of a marine vessel has a hollow tube extending through an opening through the hull, a flange attached to the tube and an opening through the flange to allow flow of fluid out of the vessel. The flange has a first surface abutting the outer surface of the hull and a second surface facing away from the outer surface of the hull. The first surface of the flange has a smaller surface area than the second surface of said flange. A diagonal surface interconnects the first and second surfaces, the lower part of the diagonal surface extending outwardly and downwardly from the first surface to the second surface to inhibit flow of liquid from the passage to the outer surface of the hull.

Abstract: A watersprite has a modified inner hull liner and an automatic liquid bailing system to reduce chemical deterioration of the inner hull liner and eventually other components of the watersprite. The inner hull liner provides a dam for water and/or spilled fuel so that the liquid accumulates at least temporarily at a location above the waterline for the watersprite. The accumulated liquid is immediately drained through a self-bailing pipe to the outside environment. The inlet for the self draining pipe is located in the vicinity of the bottom of the dam, which defines a low spot for the inner hull liner. In addition, the bilge volume between the inner hull liner and the outer hull assembly is completely filled with closed-cell flotation foam. The closed-cell flotation foam in the bilge volume helps to prevent water and/or spilled fuel from chemically attacking the hull and/or hull stiffeners in case the inner hull liner develops a leak.

Abstract: A boat has enclosed flotation within a closed bilge or floor of the boat, which is internally raised so that the interior floor of the vessel is slightly above the normal operating water line level of the vessel. The boat has bilge drain valves of a size considerably increased over the one or two square inch drains typified in the prior art. The size of these drain valves is such that, when opened, they represent a significant portion of the transom area being opened to the sea. Spring closure or manual actuation of the valve prevents the ready passage of water into the interior of the boat during heavy waves, especially during following seas which might tend to trigger a flapper operated drain valve. In combination this provides a boat that, if swamped will, even when fully loaded, have sufficient buoyancy to raise itself so that no portion of the bilge is below the water line and with the oversized valves open will have sufficient flow rate that it will rise faster than it can be reswamped.

Abstract: The passage of a scupper drain is normally maintained in a closed position by a pair of spring-biased semi-circular pivotal flaps which are mounted within a housing provided with an associated cap, thus permitting the flaps to only pivot downwardly for opening the drain to water discharge and preventing vermin from leaving the drain when the flaps are disposed in the closed position.

Abstract: The forward deck of a swath or catamaran type vessel is constructed largely of a sieve-type material, such as honeycomb-type deck grating. Should the foredeck of the vessel, which is normally suspended above the water line become submerged by plowing into a wave, or otherwise inundated by large masses of green water which would otherwise tend to weight the bow of the vessel down, the above deck water will simply drain through the sieve-type material and permit the inherent flotation of the pontoons and hull of the vessel to promptly raise the bow to relative horizontal position.

Abstract: A deck-hull coupling construction for a small-sized marine craft which has bumpers extending upwardly and downwardly from the coupling. The upwardly extending bumper is constituted by upwardly bent outer extremity of a deck flange which extends horizontally from the peripheral edge of the deck, while the downwardly extending bumper is constituted by a downwardly bent outer extremity of a hull flange which extends horizontally from the peripheral edge of the hull. These bumpers exhibit a superior shock absorbing effect and prevents a protector from coming off therefrom.

Abstract: A collapsible, inflatable boat is provided having two large inflatable tubes as hulls connected together by a floor raised above the midpoint of the hull tubes and supported by spaced-apart, laterally-extending rigid members flexible connected thereto. An inflatable, semi-tubular chamber is disposed beneath the floor and extends longitudinally of the boat midway between the hull tubes. A hinged, rigid transom is provided at the rear of the boat, and a forward end member closes the front of the boat to permit collapsing of the boat to a relatively small package without having to remove any parts from the boat.
