The Hammar H20 White Strong Rope is secured to the deck or liferaft cradle and attached to the liferaft lashing with a slip hook. If the ship sinks, the water pressure will, within four meters, activate the sharp knife, which cuts the rope, and the liferaft will float free. As the ship sinks, the liferaft painter line will stretch, and the liferaft starts to inflate. The Red Weak Link™ breaks, and survivors can board the floating liferaft.

The Hammar H20 R consists of a looped white rope line, a release mechanism, and a Red Weak Link™ (breaking strength 2,2 ± 0,4kN). The breaking strength of the H20 R is 15kN.
