Hopefully, in the unfortunate event, an abandon ship is necessary the HRU will not be used. Instead, a manual release with a release hook is favourable. The Easy Release for H20 is an accessory that will make this significantly easier and safer.

How it Works

Seeking Disabled

Inside the H20 a pin under tension sits in a notch on a spring-loaded blade and the pin is attached to the centre of a flexible membrane. At the intended depth, the increase in water pressure acts on the membrane and pushes it inwards, pulling the pin out of the notch in the blade assembly,

When the pin is fully out of the notch the blade can instantly spring forward, cutting through the strong rope that secures the liferaft's lashings to the deck. With the liferaft's lashings cut the buoyancy of the raft takes over and it can float free of its cradle.
