The Markusnet is a rescue device that enables one person to react immediately and effectively to a man overboard situation along a ship side or quay. The net enables rescuers to lift the victim in seconds, despite freeboard height of vessel, thereby greatly decreasing the level of danger. It can also be used with a crane.

It provides the ability to lift/hoist crew while standing or siting in the net. It can also be used to lift/hoist unconscious crew in a horizontal position.

The Markusnet type MS is mandatory equipment on decked vessels in several countries. It is also standard equipment in all harbors in Iceland and is now the model for international standards. It is manufactured in several standard versions, depending on freeboard height.
