Back Roll Entry

The back roll entry is a staple of boat diving, especially from small vessels like RIBs, 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.

When to Use It

• Small boats or inflatables with no space for a giant stride.
• Unstable or moving boats where standing isn't safe.
• Drift dives or timed group drops, where coordinated entry is essential.

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./li>

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 — don’t 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 — don’t jump or launch yourself.

7. Post-Entry Procedure

• Orient yourself on the surface and locate your buddy.
• Add just enough air to your BCD to stay afloat — avoid overinflating, especially in current or surge.
• 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.
