Vendee Globe non-stop, solo, round the world race
Vendee Globe skippers are carrying out tests on the communications equipment to ensure that the satellite phones are working, and on safety equipment to check the emergency beacons.
All of the information supplied by the skippers is then checked again, including phone numbers, the date when the life raft was certified and lifejacket worthiness.
In all, there are 50 checks to make.
