SDI RNLI Sea Survival Course

The purpose of the SDI RNLI UK Sea Survival Speciality Diver Course is to cover the knowledge and skills to enable divers to be better prepared and skilled to dive in the UK environment. The course covers pre-dive planning with a focus on UK sea conditions, buddy procedures, emergency equipment, DSMB use and what to do if you are lost at sea. It is an ideal introduction to UK sea diving for anyone who has completed their training primarily at inland dive sites or outside of the UK.

If you’re in danger at sea, knowing what to do can make the difference between life and death. You could be rescued more quickly or may not even need rescuing if you have the right diving survival skills and kit.

The RNLI Diver Sea Survival course will provide you with the skills and knowledge to survive. We’ve developed the course in partnership with the British Diving Safety Group (BDSG).
