A vehicle flotation assembly includes a plurality of bladders that is each coupled to a bottom side of a vehicle. Each of the bladders is inflatable to float the vehicle when the vehicle is exposed to flood waters. A water senor is coupled to the vehicle to sense flood waters rising beneath the vehicle. A pump is coupled to the vehicle and the pump inflates each of the bladders when the pump is turned on, and the pump is turned on when the water sensor senses flood waters. A plurality of anchor actuators is each of the anchor actuators is coupled to the bottom side of the vehicle. A plurality of anchors is each lowered from the respective anchor actuator when the respective anchor actuator is actuated into a lowering condition thereby inhibiting the vehicle from being floated away by the flood waters.

A safety system for use with vehicles such as boats. The safety system includes one or more inflatable bags or bladders which may prevent the vehicle from sinking in a body of water. The bags may be stored in housings, and the housings may be angled to ensure smooth deployment of the bags. A pressure regulator and one or more valves may ensure the inflatable components stay inflated so as to ensure the vehicle stays afloat. The safety system may be automatically or manually activated.

There is disclosed herein systems and apparatuses for use with personal watercraft having a top side, a bottom side, a long axis, fore and aft sections and at least one passenger opening defined in the top side between the fore and aft sections, the systems and apparatuses including at least two legs each having a first end and second end, and each attachable at its first end to the watercraft and each having disposed at its second end a wheel; an inflatable bladder attachable to the watercraft; a compressor in fluid communication with the bladder; and a control unit for activating the compressor to inflate the bladder from a stowed configuration to a deployed configuration.

A sponson attachment for an airboat allows the airboat to increase its safety and stability very quickly. A method for attaching a sponson to an airboat hull includes attaching first and second flexible tethers to a side of the sponson. The method also includes removably securing the first flexible tether to an exterior of the airboat hull adjacent a gunnel, and removably securing the second flexible tether below the first flexible tether on the exterior of the hull.

An emergency vehicle flotation system has bladder(s) attached in a compressed state on a vehicle. An inflation initiating component comprising a selected one or more of a submersion sensor attached to the vehicle to detect water pressure indicative of submersion of the vehicle and a user interface device. Selectable force gas generator(s) (SFGGs) have one gas-generating propellant cells that are individually fired. The SFGG(s) have conduit(s) that receive gas from fired gas-generating propellant cells and direct the gas to inflate the bladder(s). A controller is communicatively coupled to the inflation initiating component and the gas-generating propellant cells of the one or more SFGGs. The controller enables the emergency vehicle flotation system to receive an inflation signal from the inflation initiating component, and to fire a selected number of the more than one gas-generating propellant cells to at least partially inflate the bladder(s).

A flat-bottom fluvial transport boat comprising inflatable buoyancy tanks consisting of at least one pair of port side and starboard inflatable volumes. The paired inflatable volumes are connected to each other by means of one or more pressure balancing means.

A stabilization system for a marine vessel includes at least two inflatable bladders configured to be attached to the marine vessel, a gyroscopic sensor configured to sense an angular orientation of the marine vessel, and a controller configured for inflating and deflating the at least two inflatable bladders responsive to the angular orientation sensed by the gyroscopic sensor.
