Any idea if this was an EPIRB or a GEPIRB
What sort of coastal VHF reception does the USCG have out there? I imagine it is pretty good .
Sorry the earlier quotes aren't there so it's a bit confusing.
The Concordia sailing ship,that went down off Brazil in 2010 has had some good stuff written on the emergency respons and the way EPIRBS and satellites work.
Now, I don't definitely know if the EPIRB had GPS but I felt it very unlikely that it would be without GPS. It's was only two years ago. All commercial ships would have had gpirb by then.
The satelite gets the information for the boat and that takes 30 minutes, then it took 30 min to work out the LandL.
Then the satelite sends it ONLY to the country in the area of the distress. NO OTHER COUNTRY GETS THE INFO immediately, or at all.
Then the Brazilians tried to ring the phone number of the EPIRB info and got no answer, so the NEXT DAY they advised the USA and asked them to ring the number. NO SAR had been launched!
24 hours after the GPS was set off the first plane went out. The crew were rescued after 30 hours!!!
So you, EPIRBS are cute but not worth a pinch os sh!t compared to a cell phone, sat phone or VHF where you can TELL the USCG what the emergency is.
hats why I think this particular case of Maines coastline may be different.
Next question was the range of the USCG VHF. Well it's not "good" it's EXTRAORDINARY!
When I was near St Augustine Florida the othe ready I heard them in North Carloina clearly, then they switched to high power and it nearly blew my ear drums out 4 states away!
The first AIS targets I receive are the Coast Guard land stations, well inland.
So I would be very interested to find out how well the USCG actually receives in VHF and AIS but I think we would be quite safe to say they have great coverage over all costal waters especially with digital signals via VHF or DSC and AIS.
Last point, and its an aside, A VHF radio with DSC doesn't send any signal when the red button is pushed unless there is a GPS l and l in it either from GPS or manual input. And the manual input is too time consuming to ever be done. So I discount the DSC VHF unless the boat is full set up, and a guy with $700 is not going to have it.... Unless he has AIS and that you can use to put the GPS into the VHF.
Damn, I just found this ... I could have saved a bit of typing above! Read this and weep!
. The Concordia sank at 1423 hrs local time Wednesday. At 1425 Concordia's Bosun Geoffrey Byers swam to retrieve the EPIRB and brought it aboard the rafts. The Captain directed that someone hold the EPIRB upright at all times and keep it safe from damage. The EPIRB signal was received at 1505 hrs by the Geostationary Operational Environmental Satellite (GOES)-12. The position of the sinking, 27°28′S 40°53′WCoordinates: 27°28′S 40°53′W, was resolved at 1525 local time. The TSB report noted the EPIRB database only listed one telephone number for the Concordia and that number had not been in service since 2004.
The following morning at 0806 hrs the Maritime Rescue Coordination Centre Brazil sent a fax to Joint Rescue Coordination Centre Halifax requesting information about the Concordia. After attempting to contact the Concordia a Brazilian Air Force aircraft was dispatched at 17 hrs local time Thursday and sighted the liferafts 3 hours later.
The survivors spent nearly 30 hours in liferafts before the aircraft spotted them. Flares were fired from the rafts, and the aircraft blinked its landing lights in response and directed nearby merchant ships to the scene. The lights of the Mitsui O.S.K. Lines woodchip carriers Hokuetsu Delight and Crystal Pioneer were sighted by the survivors at 1:30 am local time and the rescue was completed by 8 am local time.
41 hours after the sinking the crew were safely aboard the rescue ships. All 64 people (48 students, eight teachers and eight crew) who were on board were rescued from 3 large and 1 small liferafts.
EPIRB is the right thing for what i am doing, and for anyone with a budget. But it's not a silver bullet, especially when one is outside the bounds of civilization of the USA, UK, Australia and some other advanced countries, like Bangladesh...
