Abstract
An underwater rescue device which delivers fresh air into the interior of a submerged vessel by puncturing a hole through the body of the vessel and forcing fresh air through the new opening. The rescue device provides for the use of an elongated housing having an internal passageway which utilizes a means for puncturing an aperture into the body of a submerged vessel. The means for puncturing an aperture may take the form of a dart which is projected by a sliding weight hammer through the body of the vessel. Once an opening is made into the body of the vessel, air is supplied through the internal passageway through the opening into the vessel. The device further provides a sealing member for the created opening for use during the delivery of fresh air.
