A marker and recovery device comprising: an enclosure adapted to be secured to a wearer; a bladder configured to fit within the enclosure in an uninflated state, the bladder comprising: an elongate tube; a first upper tube fluidly connected to the elongate tube at a first end of the elongate tube; and a second upper tube fluidly connected to the elongate tube at a second end of the elongate tube; and an inflation mechanism to inflate the bladder to extend the bladder from the uninflated state to a deployed state in which the first upper tube and second upper tube join to form a handle portion at the end of the elongate tube.

A liferaft system comprises a container for storing a liferaft, and at least one sheet of material for fitting over an exterior surface of the liferaft container and configured to heat an interior volume of the liferaft container.

A rescue system includes a wearable article, such as a wristband, which includes a radio frequency identification (RFID) tag, a radio frequency (RF) beacon, and a power supply. One or more RFID readers (collectively, an RF network) are located on a vessel, the RFID readers being configured to communicate with the RFID tag. Should the RF network detect a passenger overboard event, a modular rocket system is deployed. The modular rocket system comprises a guidance module, the guidance module including a guidance system for guiding the modular rocket system toward a target. A flight control module is removably attached to the guidance module, said flight control module including a plurality of airfoils. A flotation module is removably attached to the flight control module, said flotation module including a flotation device. A rocket motor module removably attached to the flotation module, said rocket motor module including a rocket motor configured to propel the modular rocket system.
