ABSTRACT:
An emergency locator system for locating and retrieving sunken vessels and vessels in distress comprising in combination a base, a buoyant float releasably mounted thereon and a long line connecting the base and float. The base is adapted to be mounted on an external surface of a vessel in spaced apart relationship thereto to permit fluid to circulate between the vessel surface and the base. The base comprises a hydrostatic pressure sensing-diaphragm activated float holding and trigger release assembly. The diaphragm is located on a lower surface of the base adjacent the vessel surface when the base is mounted on the vessel. The base has U-shaped grapple cables attached to it and the grapple cable ends may also be attached to the vessel beneath the mounted base. The float is adapted to be releasably mounted on the base and upon the base float being subjected to a pre-selected external pressure the float is released and floats to the water surface being connected to the base by a long locator line. The float has provisions for a dye marker embedded therein and a signaling system mounted on a top surface thereof or it may be provided without either of these or just one of them at the option of the user.
