(I think this is more appropriate here in the Multihull
forum than the Safety
forum because it is multihull-specific)
I'm getting a new offshore liferaft
in a rail-mount container.
Is a hydrostatic release necessary, is there any advantage to it on a cat, or could it be potentially detrimental?
The primary reason for the liferaft
on a cat with positive buoyancy is in case of fire, in which case I think you'd have more than sufficient time to manually release the raft before it sank low enough to trigger the hydrostatic release.
The only other way the liferaft would be immersed to trigger a legitimate release would be in case of capsize
, in which case the boat would remain afloat and you could seek refuge on the underside of the bridgedeck until a swimmer released the raft (and even then, we'd probably secure the raft on the bridgedeck and shelter in it).
On the con/detrimental side, I've read of at least one instance where premature release on passage
destroyed a liferaft.
