Backward Roll Entry

The water entry used from small, low boats: sitting on the tube or gunwale facing inward, you hold mask and regulator and roll backward into the water.

The backward roll is the entry of choice from small, low, or unstable boats, above all inflatables and RIBs, where standing up in full gear would be unsafe and a giant stride impossible. You sit on the tube or gunwale facing into the boat, fins inboard, with your BCD partly inflated. One hand presses mask and regulator to your face, the fingers often splayed so some also brace the mask strap at the back of the head, the other secures hoses, weights, or camera. On the signal, tuck your chin and simply roll backward, letting the tank lead you into the water.

It feels dramatic and is anything but: the tank takes the impact, the roll is over in a second, and the momentum carries you clear of the hull. The real risks are procedural, which is why crews are strict about them. Check behind you before rolling, another diver or the anchor line may be there, roll on the count so the boat does not lurch as weight leaves one side, and surface promptly with an OK signal, then fin away from the boat before the next diver rolls.

Small refinements help: keep your chin tucked to protect your neck, exhale gently through the nose as you hit to keep water out, and let go of nothing. Whether the day calls for a back roll or a giant stride is the crew's call and part of every dive briefing, and both entries get practiced until they feel routine during open water training.
