A fairly small hole in the hull might be enough to make a boat sink in
a few minutes.For this reason, fast hulls are particularly susceptible to
high speed impacts and might sink in less than a minute!
In this scenario we can understand the importance of a hydrostatic
release hook, that allows the raft to automatically release and inflate
when the boat sinks.
Hydrostatic release unit
2 - When the boat sinks, the
hydrostatic hook automatically cuts
the rope that secures the liferaft
to the deck. It activates at a depth
between 1 and 4 meters.The painter
line remains connected to the
weak link and the raft has enough
buoyancy to come up to the surface.
3 - As the boat sinks
further, it drags the
painter line downwards,
thus activating the life
-
raft's inflation.
4 - The resistance of the infla-
ted raft is high enough to break
the weak link and release the
painter line from the boat.
If the boat sinks in shallow water,
it may be necessary to release
the raft manually by acting on the
"pelican" hook.
1- It is therefore
essential that this
system is correctly
installed, otherwise
the liferaft will sink
with the boat.
