Boat Float is an emergency air bag float for boats. When a boat is in distress, there may not be anything to keep it from sinking quickly before it can be rescued. Boat Float is designed to attach to the sides of a boat, so it can act as a large flotation device to keep the vessel from sinking. Simply install the Boat Float system on both sides of the boat to provide extra buoyancy in case of an emergency. Boat Float can be activated manually or automatically, and it will quickly inflate to keep the boat afloat until help arrives.
