Back Roll Entry

The back roll entry is a staple of boat diving, especially from small vessels like RIBs (rigid inflatable boat), inflatables, or boats without a dive platform. It’s quick, efficient, and keeps divers low and stable on small boats where standing can be unsafe.

Step-by-Step Technique

1. Gear Prep

Make sure your tank is secure, straps are snug, and hoses are routed cleanly.
Clip off accessories like cameras or slates to prevent swinging or entanglement.

2. Position Yourself

Sit on the edge of the boat, back to the water.
Your tank should hang just past the edge. Keep feet inside the boat and knees bent.
Stay compact and steady, especially if the boat is rocking.

3. Secure Your Mask and Regulator

Use your right hand to hold your mask and regulator firmly in place.
Use your left hand to control loose hoses, hold your mask strap, or secure your weight belt buckle.

4. Wait for the Entry Command

Group entries are often coordinated by the dive master or boat crew.
They’ll usually give a verbal cue or hand signal: “Divers ready... masks on... roll!”
Make sure you’re ready early. If you're not ready, speak up and do not rush.
Entering as a group keeps everyone together, especially important on drift dives or when the boat is repositioning.

5. Look Behind You

Check that the water behind you is clear: no divers, no motors, no obstructions.
Confirm visually with crew or buddy if needed.

6. Execute the Roll

Tuck your chin.
Keep your legs together, heels close to the boat.
Lean back in a smooth, controlled motion. Do not jump or launch yourself.

7. Post-Entry Procedure

Orient yourself on the surface and locate your buddy.
Signal “OK” to the boat.
Move clear of the entry point so others can follow.

Common Mistakes

Not holding your mask and reg - can lead to flooding or losing gear.
Failing to check behind - might result in hitting another diver or landing near a prop.
Rushing the entry - especially during group rolls, can cause poor positioning or gear snags.
Loose equipment - hoses or accessories swinging during the roll can cause discomfort or snagging.
