How does a hydrostatic release unit works?

A HRU uses water pressure to activate a spring-loaded blade, cutting through liferaft securing straps. As the raft floats upwards, it automatically inflates when the painter pulls tight. Additional buoyancy from the inflated raft then breaks the “weak link”, releasing the raft from the vessel.
