Featured product | Hammar H20


The white strong rope of Hammar H20 is secured to the deck or liferaft cradle and attached to the liferaft lashing with a sliphook. If the ship sinks, the water pressure will, within 4 metres, activate the sharp knife which cuts the white strong rope and the liferaft will float free. As the ship sinks, the liferaft painter line will be stretched and the liferaft starts to inflate. The Red Weak Link™ breaks and survivors can board the floating liferaft.
