Abstract
A man overboard rescue system including a rescue line trailing from a vessel and a sea anchor pack mounted adjacent the stern of the vessel. A victim tugs on the trailing line to release a sea anchor attached to the other end of the line which causes the victim to be towed back to the vessel due to differential drag between the sea anchor and victim. The line is reeved through a one way pulley to assure the victim is towed back to the vessel. Various victim safety harnesses and alarm signal arrangements in conjunction with the system are disclosed. A spooler or storage packs may be provided for stowage of line. A line latch or brake prevents the accidental deployment of the sea anchor in heavy seas. An otherwise conventional line launcher is used when trailing a line from the vessel is impractical.
