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...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.
- 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.
