Post Rescue Collapse

^ After rescue, someone who has been immersed in cold water is still in danger from "post-rescue collapse." As blood pressure drops, inhaled water can damage the lungs. Cardiac arrest or arrhythmia can develop as cold blood is released from arms and legs into the body core.


Where do you usually go boating, or where would you like to go? Check out the water temperatures listed below and then refer to the hypothermia chart. If you fell overboard and lost your boat, how long could you expect to survive?


Life jackets can keep you warm and help save your energy. If you are not wearing your life jacket, your expected survival time is a lot less.

^ It is vital to treat the victim gently and get immediate medical care.

The best way to avoid the effects of cold water immersion and hypothermia is to wear a life jacket at all times when boating. This can keep your head above water if you capsize or fall overboard, giving you precious minutes to get back on the vessel. If you cannot rescue yourself, a life jacket can give you some hypothermia protection and extend the time you can survive until someone rescues you.

This chart shows how long someone may survive at various water temperatures.

How To Have A Perfect Boating Experience

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
