| 20080229997 | Flotation Device, Method of Mounting Same and Operation Thereof - Flotation device which comprises an exterior receptacle which is designed to be supported on the external surface of a ship, cargo container or floating structure in such a manner that it extends substantially within the ship, cargo container or floating structure, leaving its open end oriented toward the outside; and, inside of said exterior receptacle, an interior receptacle whose open end corresponds to the open end of said exterior receptacle and which houses inflatable means and expulsion means for expelling said inflatable means from the open end of said interior receptacle following the activation of the flotation device of the present invention. | 09-25-2008 |
| 20080257248 | Portable Emergency Floatation System For a Vessel - An emergency floatation system for a vessel in a body of water includes a portable canister having a removable lid; and an inflatable bag contained in the portable canister in a collapsed or deflated form, and wherein the inflatable bag is removable from the canister and inflatable to provide buoyancy to the vessel in an emergency condition. | 10-23-2008 |
| 20090056614 | Floatation Element for Vessels and Vessel Comprising One Such Floatation Element - The invention relates to a flotation element for vessels, consisting of concrete comprising closed-cell expanded foam beads, such as polypropylene beads, which are coated with a flexible binder, such as polyurethane, whereby the unfilled inter-bead volumes do not exceed approximately 20% of the volume of the floatation element. Preferably, one such floatation element comprises a concrete core as indicated above, a polyurethane coating around the core and a bonding film, such as polyurethane, which is disposed between the core and the coating. The invention is suitable for the construction of vessel floats. | 03-05-2009 |
| 20090090290 | KAYAK-STABILITY SYSTEM - A kayak stability system that stabilizes a kayak and supports a kayaker in water such that he or she can more conveniently enter or re-enter the kayak from the water. The device includes at least one sponson attached to the kayak and retractably moveable from a stored position along an exterior surface of a hull of the kayak to a deployed position over the water to provide added buoyancy to the kayak for stabilizing the kayak and a stability arm for supporting the kayaker in the water. At least one stabilizing arm is also pivotally attached to the kayak and retractably moveable from a stored position along a surface of the hull to a deployed position over the water in spaced relation to a corresponding sponson. A combination of the deployed sponson and stabilizing arm provides support to a kayaker to allow the kayaker to more conveniently enter or re-enter the kayak from the water. | 04-09-2009 |
| 20100147205 | EMERGENCY ENCAPSULATED LIFT SYSTEM - A buoyancy lift system having an inflatable bladder with a tether stowed inside a canister secured to a vessel. A sealing member is slidably received within canister and secures to the inflatable bladder. Pressurized gas forces the sealing member and bladder outwardly of the canister. A stop prevents the sealing member from escaping the canister such that the sealing member creates a seal between itself and the canister at an outboard end of the canister. Pressurized gas is forced through a channel in the sealing member into the bladder to increase the displacement of a vessel. | 06-17-2010 |
| 20120199058 | Watercraft - The disclosed invention is directed to a watercraft which comprises at least one main force member attached to at least one wing; the main force member and/or wing and/or a float attached to the wing comprise sufficient displacement to provide flotation for the craft and its payload. Connected to the main force member is a force transmitting member, to which the engine is connected. The engine may comprise a person or another engine (conventional, electronic, wind, etc.). The engine may comprise a weight which undergoes vertical translation, thereby producing the force transmitted by the force transmitting member to the main force member. | 08-09-2012 |
| 20150314839 | RETRACTABLE STABILIZER FOR WATERCRAFT - A user floatation system for boating safety is provided. The system includes a retractable stabilizer for use with a watercraft. The system includes a float system, coupled to a hull of the watercraft to stabilize the watercraft during use. The float system includes a float, a frame system and a float system. The frame system comprises frame members for coupling the frame system to a watercraft. The float rotating system operatively coupled to the frame system. The float rotating system includes a stabilizer arm coupled to a rotating support at one end thereof, and coupled to the float on an opposite end thereof. The float is moveable between the stored position and the deployed position in response to operation of the float rotating system. | 11-05-2015 |
| 20150360758 | LONGITUDINAL SCOOPS FOR ROLLING STABILITY - The invention generally relates to devices for stabilizing floating structures and systems and methods utilizing such stabilization devices. Some embodiments of the stabilization device include a fabric material having a collapsed configuration and an expanded configuration. The expanded configuration of the fabric material may form a column of the fabric material. The column of fabric material may define an internal volume. The front end of the column of fabric material may be closed, and the back end of the column of fabric material may define an opening for receiving water for filling the internal volume. When filled with water, the stabilization device may improve roll stabilization of a floating structure. The floating structure may be a flotation device of an emergency flotation system, boat, or inflatable raft, for example. The emergency flotation system may be used with aircraft, (e.g., helicopters) to provide stabilization when the aircraft is ditched in water. | 12-17-2015 |
| 20150375838 | BOAT COLLAR ATTACHMENT SYSTEM AND METHOD - A watercraft with outboard stabilizing members on a hull with a bow wrap and port and starboard side sheets with one or more longitudinal channels. The port and starboard stabilizing members comprise buoyant members in a sheath having one or more longitudinal keepers that are configured to be received into the side sheet channels. Tension members extend through the keepers, and are attachable near the aft end of the watercraft, and releasably engage tensioning mechanisms in the bow wrap, for releasably attaching the stabilizing members to the side sheet. Deck access plates through the side walls provide access to the tensioning mechanisms, which may be, for example, crank or electric winch mechanism. | 12-31-2015 |
| 20160159445 | FLOTATION DEVICE FOR A LIGHT-WEIGHT WATERCRAFT - A floatation device for a light-weight watercraft having a hull includes a frame member having a hull engaging member and float engaging member, and at least one float is held on the float engaging member. The floatation device is located below the hull of the boat. The hull engagement member is either a post for engagement with a scupper through the hull, or a strap for engagement with the gunwale of the watercraft. The float engagement member includes at least one member for engagement with the float. The float has a generally conical front end and a longitudinal hole therethrough for engagement with the member of the floatation engagement member. | 06-09-2016 |
