Student invents lifejacket to ward off hypothermia

by Gizmodo/Sail-World Cruising on 2 Nov 2013
Hydro - the goal is to keep the vital parts of the body warm SW
Innovation and invention has already brought us an incredible increase in ocean safety for the cruising sailor over the last few years with EPIRBs, PLBs and generally better mousetraps in many areas. Now a final year student has been putting his mind to work on how to stop overboard crew from dying of hypothermia before help arrives.

Irish student Kieran Normoyle has come up with a better inflatable life jacket design that protects against shock and hypothermia from freezing temperatures.

It's early days yet, but according to technology magazine Gizmodo, his creation, known as Hydros, is actually more of a life jacket system made up of three different components.

At its core is a t-shirt featuring manually activated gel heat packs over the heart, carotid arteries, jugular veins, and other vital areas that help keep the wearer's blood warm as it's pumped towards the brain.


The heat packs can maintain a temperature of 140 degrees Fahrenheit for up to eight hours, helping to fend off the effects of hypothermia.

Further protecting the wearer against frigid ocean temperatures is a waterproof jacket that works like a wet suit to trap body heat and provide extra insulation.

And finally the Hydros of course includes a zip-up inflatable life vest with an innovative offset design that serves to keep the wearer face up—and can even automatically flip someone over to help prevent secondary drowning where liquid in the lungs can be fatal.

The catch, of course, is that the Hyrdos seems better suited to disaster situations where crew have enough time to properly put the life jacket system on. For cruising sailors this could without a doubt help save lives in the event of a disaster.

The system is one of the finalists in the http://www.gizmag.com/!Gizmag James Dyson Award for 2013.

Watch the video he has made, which will show more about how the three systems work together, here:

This all stems from the learnings in the widely read, ‘Debbie says there are 7 Ps and 1 C with insurance’. This all stems from the learnings in the widely read, ‘Debbie says there are 7 Ps and 1 C with insurance’. As time unfolds some more, we learn that indeed there are a lot of reasons you need to apply patience with both your dealings with your insurance company, and also all the many trades that are working feverishly to get all the jobs done.

Fourteenth blog from on board Perie Banou II - British Virgin Isles
32 days back I departed the British Island of Saint Helena. Clearing port, customs, immigration simple. Jon has arrived in the BVI ahead of his estimated arrival. He had somehow managed to completely disconnect from the on-board communication system that they set up for him, and as a result we didn't have communication with him while he was at sea. of course, that is nothing strange for Jon, and perhaps he wanted it to be more like his circumnavigations of old? Hmmmm.... Accidentally on purpose?

Debbie says there are 7Ps and 1C with Insurance
Debbie says there are 7Ps and 1C with Insurance If you have been on the planet or around boats long enough, you’ll know all about the 7Ps. The one ‘C’ mentioned here refers to consequence, and in the legalese that surrounds insurance, it gets applied distinctly to consequential damage. We’ll come back to all of that in a while, but for now, our mission is to look at the consequences of actions prior to TC Debbie making landfall.
