What to Do if You Surface Far From the Boat

You finish the dive and reach the surface only to realize the boat is nowhere nearby. Maybe it drifted. Maybe you did. Maybe the current was stronger than expected. Either way, you are now floating far from your exit point, and the crew might not even see you yet.

This situation can feel alarming, but it does not have to become an emergency. As long as you stay calm and think clearly, you can manage it. Here is what to do.

Step 1: Get Buoyant and Stable

• Add just enough air to your BCD to become positively buoyant. Avoid overinflating as it can make it harder to maintain a stable position at the surface.
• Keep your regulator in your mouth. Surface conditions can change quickly. Waves and chop can surprise you.
• Keep your mask on. It will help you see better and protect you from splashes.

This is not the time to relax or chat. Stay alert, visible, and efficient.

Step 2: Deploy Your Surface Marker

If your DSMB was not already deployed during ascent, now is the time to send it up. A tall, upright marker is one of the best visual signals you can use in open water, especially in rough conditions.

If you did send one up earlier, you have already increased the chances that the crew knows where you are.

Step 3: Assess Before You Act

Take a moment to evaluate your situation:

• Is the boat anchored or drifting?
• Are other divers still surfacing?
• Is the current pulling you away or moving in the same direction as the boat?
• Can the crew see you?

If the boat is drifting and you are drifting with it, the best move is often to stay put. Let the boat come to you.

If the boat is anchored and the current is carrying you farther away, you may need to swim—but only if it is clearly manageable.

Step 4: Signal for Pickup

Use your available tools to make yourself visible:

• Hold your SMB upright or wave it side to side
• Wave your arm if the boat is visible
• Use a mirror or flashlight if conditions require it and you are trained to use them

Avoid using air-powered signaling devices. These draw from your tank and are usually unnecessary if you have proper visual tools and the crew is alert.

If your buddy is with you, stay close. You will be easier to spot as a pair.

Step 5: Swim Only If It Makes Sense

If you are sure you need to swim:

• Keep your mask on and regulator in place
• Swim slowly and steadily. Do not rush
• Stay horizontal in the water to reduce drag
• If the current is pushing you, swim at an angle to compensate rather than directly at the boat

Remember, swimming is not always the best move. You may be easier to find if you remain in place and conserve energy.

What Not to Do

• Do not remove your gear
• Do not drop weights unless it is absolutely necessary for survival
• Do not descend again, as that could make you harder to locate
• Do not panic if the boat does not immediately approach. The crew may be assisting other divers or repositioning

Quick Recap: What to Do If You Are Far from the Boat

• Get positively buoyant, but do not overinflate
• Keep your regulator in and mask on
• Deploy your DSMB if it is not already up
• Signal with your whistle or mirror
• Assess conditions before choosing to swim
• Stay calm, stay close to your buddy if present, and conserve energy
• Let the crew come to you unless you are sure it is safe to swim
