Im Au this race would be a Cat 4 offshore race..
Each crew has a personal epirb as well as one for the boat.. each crew has a personal offshore jackets incorporating inflatable vest and must b worn at all times when on deck.. Life lines are to be used (generally twin so at least one is clipped on when moving).. At night lights are to be kept by each crew on watch.. Automatic life rafts to the new standards are manditory as well..
The rule is you have one life.. sail safe.. These safety rules should b used by monos and cats..
