Re: How a Shipwrecked Crew Survived 10 Days Lost at Sea

Not sure you can completely discredit the media but you do need to remember that most reporters are not sailors and the people they report on arenít always forthright. Mix the two and you get reports that make no sense to anyone versed in the topic being written about.

Re: How a Shipwrecked Crew Survived 10 Days Lost at Sea

In an effort to try to put some usefulness into this thread, I have had difficulty trying to find the absolute scientifically proven and approved recommendations as to the best way to survive the longest in the event of a tragedy like this one. I once did a lot of research on the USS Indianapolis which was sank in WWII where the crew treaded water for six days before rescue but there really is not a consensus as to what is the very best way to survive the longest. This should probably be the beginning of a new thread. Does anyone know of a reference where there are authoritative instructions for surviving ocean wrecks ?

This would depend entirely on what you had with you when the boat when down?
Nothing? hope you can tread water for many days.

Life raft and some emergency supplies - ration it and make it last

handpowered watermaker? ration your food (and water)

It simply will depend on many factors - a couple once shipwrecked off the Galapagos, got their raft and dinghy (wooden boat) in the water some supplies etc and managed 117 days - both more dead than alive when rescued - lived off booby birds, turtles and rainwater - but they made it

Not giving up is one characteristic of disaster survivors.

Re: How a Shipwrecked Crew Survived 10 Days Lost at Sea

According to Mario Vittone*:
“... the average time to rescue at sea following a distress call with location data is 4.5 hours. You don’t need to take a class on how to ration the water between four people if you’re going to be picked up in time for dinner. You will not be trying to catch fish with your hands, or tackling seabirds that land on your raft or go mad drinking the seawater after weeks at sea. There is plenty enough boating safety stuff to learn without worrying about what to do if none of it works ...”

It sounds like he is describing "coastal US" - and average response time when location is given. Get further out to sea, then depending upon which satellites are in your coverage area, and whether your epirb provides location data - it could be several hours before you're located; then time to send rescue units, or locate the nearest available help - and the rescue can be a day or more away.

try setting off you beacon halfway between the Marquesas and Hawaii - see if you are rescued within 4.5 hours. I might believe 4.5 days...............

Re: How a Shipwrecked Crew Survived 10 Days Lost at Sea

Gordy mentioned average 4.5 hrs. Even if you aren't picked up immediately, if your EPIRB is gps equipped, someone is working on getting rescue equipment to you within a couple minutes of activating your EPIRB. If your old EPIRB is not gps equipped, expect longer position time due to orbiting satellites to give your position. If there aren't any merchant vessels close, you can expect a C-130 to locate you if you are beyond helo range. C-130's are pretty fast, then they'll get a ship to pick you up. I spent years tracking every EPIRB case in the US Jurisdiction.

Re: How a Shipwrecked Crew Survived 10 Days Lost at Sea

Amazing that they lost their rigging with no one on lookout then a ship came up to them (.5 mile) before they saw it , no lessons learnt from the 1st mistake.

Hopefully they all sit back and learn from their mistakes,

No lookout 24/7
Non prepared boat with battery flying through the cabin and water/ food wiped out from one roll over

hope they donít sail near me enough problems without 3 more to dodge on the water

I agree this all seems to stink when the coast guard reports different circumstances.

I believe you stand a good chance of early rescue if you are coastal. On passage - you are just out of luck unless there is a passing ship.

Re: How a Shipwrecked Crew Survived 10 Days Lost at Sea

The USCG takes epirbs serious, A couple of years ago I had a call at midnight about one I had unregistered at least 14 years prior. I even lived at a different address and phone number. It went off, off the outer banks.
I think it had been stolen out of a shed. And activated by some dumb ass. I don't know the end of the story, I would have given it to some commercial fisherman which I'm sure is where it was..

Re: How a Shipwrecked Crew Survived 10 Days Lost at Sea

Very interesting read and I hope it will teach me a lesson.


Stuff like flying batteries, etc. you know. Basics.



Also the repeating story of passing ships indifferent to flares and smoke.


I think we could all benefit from better planning and better use of toys like epirb, ais/dsc personal beacons, InReach SOS, and such likes.


Why do we use mickey mouse marine flares if a new year show fire cracker makes so much more noise and light ??????????



To get broken is one mistake. Then to be unable to call out is another.


Thanks for sharing!

It boils down to statistics and math. When someone says “average” without specifying “statistical mean” or “arithmetic mean” [pronounced arithMETic mean] it can lead to confusion.

It is entirely possible that half the rescues with Epirb activation take less than 4.5 hours, and half take more - possibly much, much more. This would make 4.5 the statistical mean - also called the “median”. The arithmetic mean (what most of us call “average”) could easily be much higher. Say you had 4 rescues that happened in 4 hours and 1 that took 5 hours and three that took 4.5 days. The statistical mean (or median) is between 4 and 5 hours (half before and half after), but the arithmetic mean is 1.8 days (total time divided by number of rescues.)
So while the CG stats may be correct, they may also be a bit misleading. The quote above was not clear. And let’s also remember that they are tabulating Epirb distress calls. The particular episode discussed in this thread does not enter into the equation.

I keep watch and carry an Epirb... and a sextant.
