What To Do When You Surface and You Cannot See the Dive Boat

While diving, no diver wants to surface after an exhilarating dive to find no sign of the dive boat in any direction you look. On the off chance that this was to happen to you, then you should know what to do.

Do not panic.

The boat could be near, but you missed it. Even a small chop makes waves higher than your head, and unless you are looking in the right direction at the right time, you can miss a boat only thirty meters away. Inflate your BCD so that your head is as high as possible, and do a slow 360-degree inspection of the horizon.

Activate Your Signal Devices

If the boat is nowhere to be seen, it may be because the ocean swell is blocking your view of the dive boat, and the boat crew may have the same problem locating you. In these cases, audible signalling devices are especially helpful. Therefore, both a visual and an audible signalling device is considered standard equipment for recreational divers.
The key to getting noticed is being tall, vivid, and loud. Every diver ought to carry a visible signal in the form of an inflatable safety sausage (SMB). SMBs are long, vibrant tubes deployed on the surface to draw the attention of the boat crew and tell other boats you are there. Also, make use of an auditory signal like the Duo Alert air horn. Deflate your BC enough to submerge your ears before sounding it as the blast could damage your hearing.

Waiting For Help

If the dive boat has clearly departed you behind, in most cases it is best to wait where you are to be rescued. If you are near a mooring buoy, hang on to it so you do not drift. Now is the time to toss or drop your weights; you can also ditch your tank if you feel that is necessary. Keep everything else.
If you find yourself in an open ocean, watch for any passing boat or plane and be ready to signal them. Stay calm and keep physical contact with your buddy, as it’s easy to become separated in choppy seas. Keep your arms and legs close to your body to conserve body heat. Furthermore, do not give up hope. As a scuba diver, you have all the key devices to maximise your chance of rescue.
