Hammar Lifebuoy Release System

The difference between life and death when someone goes overboard from a ship or vessel can be the time it takes to launch a lifebuoy to the person in the sea.

The Hammar lifebuoy system is a complete, easy-to-fit package for the rapid launch of lifebuoys onboard a ship. Most other lifebuoys on the market are installed in a holder on the bridge wing or a similarly remote location, to which access may take precious time.

For a shipyard, the system offers easy installation and trouble-free sourcing, as all parts are delivered in a complete package. The GRP holder can be mounted on both starboard and portside. The system is cost-effective, not only because it saves time but, more importantly, it may even save lives.
