The RNLI is the divers' friend, as this TV series reveals.

In 2012 Marlin Sub-Aqua Club’s members changed our bye-laws to say that, should we ever hang up our fins, sell all the club kit and disband the branch, then instead of returning the proceeds to our members we’d donate the lot to the RNLI. Find our why we love these guys so much in an hour – 9pm on BBC1, episode 2 of Saving Lives At Sea‬, (catchup now on iPlayer). Love ‪diving‬? Join us.
