A variable volume raft containing adjustable ratio and amounts of air and or water. The buoyancy and ballast of the raft are routinely adjusted to accommodate additional occupants and changing weather conditions. A manual pump can be the primary or back up source for initial inflation. The torque pump twisted by hand or amplified by a lever arm generates air pressure for maintenance and repairing deflating lacerations at sea. The pumps collector gathers and pressurizes rain water for drinking in one chamber while pressurizing sea water as a stabilizing ballast in another chamber. A double hull or full floor chamber allows huge variations in buoyancy or ballast as dictated by changing needs for stability versus mobility. A compressed liquid or two-part foam confers puncture resistance to a portion of the raft. A thrown self-righting manual air horn, worn water-activated air horns and water activated transmitted signals, mark the site for rescuers.
