The back roll is the entry of choice when entering from a small boat. To perform a back roll entry, use the following procedure.

1. Sit on the edge of the boat with your back towards the water.
2. Place all hoses and gear at or near your chest.
3. Place the regulator or snorkel in your mouth.
4. Place either hand over your face so it secures both your mask and snorkel.
5. Place the other hand over back of your head to protect it from the cylinder valve.
6. Make sure the area behind you is clear.
7. Tuck your head down towards your chest and allow yourself to fall backwards into the water.
8. Display the OK signal as soon as you surface.
