Your boat capsizes but remains afloat. What should you do?

The answer

If your boat capsizes but remains afloat, you should stay with the boat. This is the single most important rule in a capsize situation. A boat, even overturned, is much larger and more visible than a swimmer, so staying with it dramatically increases your chances of being found and rescued. Climb onto the overturned hull if you can, or hold on to it. This keeps you out of, or higher in, the water, which conserves body heat and energy while you wait for help.

Swimming for shore is one of the most common fatal mistakes. Distances over water are deceptive, currents and cold sap your strength, and once you leave the boat you become nearly invisible to rescuers. Unless the shore is very close and you are certain you can reach it safely, stay put.

Step-by-step capsize response

A calm, ordered response saves lives:

Keep your life jacket on (you should already be wearing one) and stay calm to control your breathing.
Do a headcount of everyone who was aboard, and make sure no one is trapped under the hull.
Stay with the boat. Climb onto the hull or hold on to it to stay as far out of the water as possible.
Signal for help. Use a whistle, flares, a mirror, waving arms, or bright clothing to attract attention from other boats or shore.
Conserve energy and body heat. Avoid unnecessary swimming or movement, which drains heat and energy.

Cold water and the HELP position

Cold water is a serious danger even in summer. Sudden immersion can cause cold water shock, an involuntary gasp reflex and rapid breathing that can lead to drowning in the first minute, so it is vital to get your breathing under control. To slow heat loss while waiting, adopt the HELP position (Heat Escape Lessening Posture): draw your knees to your chest and hold your arms against your sides. If several people are in the water, huddle together to share warmth. Staying with the boat and, ideally, out of the water on the hull, is the best defense against hypothermia.

Why other choices are wrong

Exam distractors usually include "swim to shore," "dive under to retrieve gear," or "remove your life jacket to swim faster." All are dangerous:

Swimming to shore risks exhaustion, cold, and losing visibility to rescuers.
Diving under the boat wastes energy and heat and risks entanglement or injury.
Removing your life jacket is never correct; it is your primary flotation and the reason you can stay afloat while waiting.

The safe, tested answer is to stay with the floating boat, account for everyone, signal, and conserve energy until help arrives.

Frequently asked

Why should you stay with a capsized boat?

A boat, even overturned, is far larger and more visible than a swimmer, so rescuers spot it much more easily. Staying with it also gives you something to climb onto or hold, conserving energy and body heat while you wait for help.

What should you do if your boat capsizes?

Keep your life jacket on, stay calm, and do a headcount. Stay with the floating boat, climb onto or hold the hull, signal for help, and conserve heat and energy. Do not try to swim to a distant shore.

How do you signal for help after capsizing?

Use a whistle, marine flares, a signal mirror, or wave bright clothing or your arms. Staying with the larger, more visible boat makes these signals easier for passing vessels or people on shore to notice.

What is cold water shock and how do you survive it?

Cold water shock is an involuntary gasp and rapid breathing triggered by sudden immersion in cold water, which can cause drowning within the first minute. Survive it by keeping your life jacket on, controlling your breathing, and adopting the HELP position to reduce heat loss.
