Abstract: A boat ignition safety apparatus and method that prevents a gasoline engine of a boat from being started until the enclosed engine compartment has received proper ventilation for a predetermined period of time to ensure dangerous gasoline fumes have been removed. The invention uses an air pressure sensor to detect fresh air drawn into an engine compartment by a ventilation fan or blower. When this takes place a positive pressure develops within the engine compartment. This positive pressure is detected by the air pressure sensor and indicates that the ventilation fan or blower is operating properly. The present invention makes boating safer by ensuring adequate ventilation of volatile gasoline fumes, thereby preventing accidental explosions that can occur when a boat's engine is started.

Abstract: An externally threaded nipple (24) fits through a circular opening (38) in a flexible wall (14). The nipple (24) is carried by a first ring member (18). An internally threaded second ring member (20) is screwed onto the nipple (24). The first and second ring member (18, 20) become connected together and the portion of the flexible wall (14) that immediately surrounds the opening (38) is trapped by and between two inner side surfaces (30, 36) of the two ring members (18, 20). Projecting portions (50) on one of the inner side surfaces are urged against the wall (14) to inhibit rotation of the attachment (16). One of the ring members (18, 20) has louvered fins (42) interconnected by strengthening ribs (44).

Abstract: A hatch for venting enclosed spaces has at least one carriage slideably mounted on a circular track so that the hatch may be opened in any direction to provide maximal ventilation. The circular track has a “T”-shaped cross-section that is slideably engaged by the carriage. The carriage carries a lockable hinge that interconnects the carriage and a hatch door. In operation, the carriage is moved around the track until the hatch door is oriented with respect to wind so that an optimal amount of air is directed by the hatch door into the enclosed space to be ventilated. The carriage can be locked into position at any preselected point on the track. The lock is spring-loaded and it is therefore easy to unlock the carriage and re-position it when the wind changes directions.

Abstract: A portable collapsible ventilator that is used to direct air currents into a boat hatch, recreational vehicle vent, or other opening in an enclosed space while, at the same time shielding that opening from the intrusion of rain and direct sunlight. The ventilator has a frame of hinged, flexible rods covered with a water repellent fabric with an opening at one end. The ventilator is erected into a freestanding unit by pushing down on the hinge point of the flexible rods and locking them in position with a locking mechanism to form a semi-circular shape. A rod is inserted between the front and center hinge points to extend the open end of the device forward into a rain and sun shielding position. The ventilator is then positioned over the opening to be ventilated and secured in place with attached shock cords. When not in use, the ventilator is collapsed into an elongated shape with the flexible rods aligned and the cover folded around them to enable insertion into a storage bag.

Abstract: A portable windscoop for boat portholes fabricated of a flexible plastic or similar material with flange portions at its side periphery. The windscoop is adapted to be pressured into a curved body, scoop or funnel having an open end. The flange portions are adapted to be snapped into the side portions of an open porthole with the natural tension of the plastic or similar material serving to hold the scoop in place with its open end facing the bow of the vessel. Wind is thus directed into the interior of the vessel through the open porthole having the windscoop in place in both rain or shine. The scoop is readily removed by pressing its sides and thus releasing its flange portions from the side of the porthole.

Abstract: The invention provides a naturally vented cockpit of a boat. To achieve this natural ventilation, the invention utilizes the high pressure zone formed when air flows over surfaces of a boat and is forced to change flow direction, when the boat is in forward motion. One of these zones is located in the vicinity of the base of the windshield and the foredeck of the boat. An air scoop is located in this vicinity to funnel air into an air passage that extends beneath the windshield and into the cockpit. The terminal end of the air passage is preferably located near the base of the inside surface of the windshield to direct air onto the windshield, thereby minimizing the risk of fogging and condensation on its surface. Moreover, the fresh air entering from the air scoops can be used to maintain a slightly positive pressure in a cockpit that is under full canvas. As a result, the concentration of combustion of gases in the cockpit is reduced, providing a healthier environment for the occupants.

When the hose-and-fitting assembly is secured in a port, the fingers both lock the fitting in position and compression secure the hose to the fitting.

Abstract: A portable collapsible ventilator, with a fabric enclosure intended for mounting over a hatch or porthole opening on the deck or hull of marine craft or other similar enclosed spaces. The ventilator consists of a bonnet shaped fabric enclosure which is attached to an opening frame made up of two members hinged at one end. The open ends of the opening frame are held apart at approximately the width of the hatch opening and maintained at that distance by means of a rope or line secured at both ends. The opening frame is made of a resilient material such that when the hinged end is pushed down, the two segments of the opening frame bend outward forming an oval shape and when thus compressed the ventilator may be secured to the deck of the boat or surface of enclosure by means of a pair of lines extending from the hinged point to a retaining bar inserted through and secured under the hatch opening.

Abstract: A ventilator wind scoop system is disclosed for attachment to a boat deck hatch having a hinged hatch cover which opens to uncover the hatch opening whereby the scoop system communicates through such opening with the boat's below deck space.
