The last resort for getting out of the water when the tide’s come in and you need both hands free to climb. Sure, it looks obvious, but tell that to my mate Greavsie (and presumably thousands of others) who’ve had to use their teeth to climb out of the surf still holding their board under one arm. The poor guy left half of his molar enamel on a rusty hunk of iron in a seawall, when a sling would’ve been so much easier...

1. Attach your leash’s ankle part to the rail saver. 2. Put loop over head and neck and under one arm in the armpit, take up the slack in the leash with one hand. 3. Climb out of the drink with board dangling, both arms free to climb. Sure, it’s gonna dangle about a bit, but it’s better than waiting six hours for the tide to go out, especially if there’s something good about to start on TV.
