• Fold in half down the
centre line, and repeat
this process twice more
until you get the shape
to the right.
Sea anchor
The sea anchor is used to stabilise the SAR unit in a head to
sea position, which can be used in a number of emergency
situations. If at any point the boat is left without engine
power due to engine failure, swamping or fouled propellers,
the sea anchor should be deployed. To do this, release the
securing latch on the sea anchor stowage, then deploy
the folded sea anchor and weight directly up sea. The sea
anchor is secured independently and does not require
attaching to a cleat. It will only hold the boat head to sea
once all the slack has been taken up and the anchor has
opened out, therefore it is always advisable to deploy it
as soon as engine power fails. The sea anchor can also be
used to stabilise the boat during helicopter transfers.
During recovery the helm should use the engines to take
the load of the line whilst recovering, once the sea anchor
reaches the surface, pull one of the four strings as this will
allow the water to spill out and remove the weight out of
the anchor.
The sea anchor should be stowed by faking the line into
the stowage then folding the anchor and placing the sea
anchor in with the weight on top (see the image below).
To fold the sea anchor, proceed as follows:
• Fold the sea anchor in
half and lay it flat on
the deck of the lifeboat
with one of the sewn
in rope lines in the
middle. Ensure all the
lines connected into
the main sea anchor
line are coming out of
the bottom.
• From the points on the
outside folded edge of
each side, fold into the
centre and down to the
bottom point creating
a diamond shape.
• Fold the two outer side
points into the centre
and slightly down,
so creating a kite like
shape as shown to
the right.
• Role the sea anchor
from top to bottom.
• Once the sea anchor is rolled up, wrap the lines around
the sea anchor until the weight is on the sea anchor.
• Place the sea anchor in the stowage box, with the line
towards the bottom of the pot and the weight on top of
the sea anchor as shown below.
• Close the lid and slide the retaining pin towards the
starboard side, lower the thimble from the lid of the
stowage into the gap and release the pin.
