A vessel is a lot easier to spot than a person or persons in the water. Do not remove your lifejacket and, if you are in the water, stay together in a HUDDLE or HELP position.

Do not try to swim ashore unless it is very close and a suitable landing place exists. Distances can be deceptive. 

Try to get the EPIRB and distress signals out of the capsized vessel and raise the alarm. Make yourself as visible as you can to both ships and aircraft. Put on more clothes if you are able to. They will help to keep you warm and may delay the onset of hypothermia.

Abandon the vessel as a last resort and take the EPIRB and distress signals with you. Switch on the EPIRB and leave it on until emergency services tell you to turn it off.
