And there is potential delay there, because there is time between when your EPIRB transmit Mayday signal with location data to the satellite, and when that information is transmitted back to the land station. - an AIS PLB will connect to GPS satellites to calculate your position, but will transmit that information only on the AIS-B platform, i.e. VHF frequencies; and this is "visible" only in a very local area around you (at best, knowing that you are low on the water, and with big waves).

It doesn't seem he ever picked up the AIS signal of the PLB (unless I missed it). AIS PLB only the first contact first guided by position from HQ. No AIS PLB final contact as Kevin zipped up in raft trying to sleep waiting for daylight and JLC. So AIS PLB signal screened IF it was even turned on, him knowing that. Turned off he would have turned it ON close to planned daylight recovery . That wasn't necessary as JLC came early in the dark, guided by the strobe. Share this post Link to post Share on other sites
bucc5062 171 #6504 Posted December 2, 2020 11 minutes ago, jack_sparrow said: If in one piece with keel no but snapped off probably a floater, but no longer skyward. Kevin's comment (that I read here) was that he was not able to stay on the boat, as in swept off, from the stern which would indicate a boat going down. Based on eye-witness reports, the bow turned 90 degrees within x secs (lets say 4). The main cabin was flooded almost within that time (barely got a message out before electronics died) and at or just past 2 minutes he was in the water then in a life raft. Y'all know so much, I get that, but reason would indicate that with that amount of volume flooded that quick, what little air pockets in the bow or stern would not have been enough to compensate for the amount of water "ingressed". These boats are light, but not that light. You consider a snapped keel, but there was nothing indicated from Kevin, nor did he say the rig fell. You have a boat full of water with a mast and sail attached, foils attached, keel attached, but just snapped in half...If this thing is floating then it should be found, hauled out and inspected for why/how it snapped. Why? Because y'all keep talking about how this time the new foils are an "experiment" and if/when one fails...gather data. Good guess it is like the Titanic, it found a watery grave deep in the (Atlantic?) ocean. My 1 cent, but honestly Jack, you taught me not to speculate too much. The boat is gone. Kevin is not. He and JLC are swigging wine (pure speculation, but a great image) as they await Kevin's removal and the race continues. btw, Isabelle has eaten more into Sam's lead on her. This sailor, if this is her first is doing amazing. Coming round CoGH, there is still a tight race and that is very cool and fun. Share this post Link to post Share on other sites

And both of us pulled it to get the life raft as close as possible to his boat, and when I was close enough I jumped and caught the back of the boat." "He said 'Are you on board, are you on board Kevin??!' he was very happy. I said, 'Yes I am on, I'm sorry to disturb your race Jean.' We had a big hug."

Zonker 2,496 #6551 Posted December 2, 2020 1 hour ago, Laurent said: Please explain to make sure I understand. So if I got it right: - an EPIRB will get data from GPS satellites to calculate your position AND transmit that position to a series of "low altitude" satellites that will transmit that information to terrestrial stations, if you trigger your emergency button. And there is potential delay there, because there is time between when your EPIRB transmit Mayday signal with location data to the satellite, and when that information is transmitted back to the land station. - an AIS PLB will connect to GPS satellites to calculate your position, but will transmit that information only on the AIS-B platform, i.e. VHF frequencies; and this is "visible" only in a very local area around you (at best, knowing that you are low on the water, and with big waves). Is that correct? Mostly. Some EPIRBs "GPS EPIRBs" get position data from GPS satellites and broadcast that position. Locates your position very accurately (within metres) Cheaper EPIRBs just say "help" and the SAR sats have to figure out the position. This takes longer (requires multiple satellite passes), a less accurate position, and has a larger search area (a few square km). EPIRB's has a battery life of 48 hrs at -20F PLBs are smaller than EPIRBs and have a battery life of 24 hrs. Just like EPIRB, some have a GPS built in, and some do not. AIS rescue beacons have a GPS receiver to know their position and broadcast a VHF short range signal to local rescuers Finally you can combine these categories like AIS/PLB into one device.

AIS message is mmsi/nav status (this is where the SART declaration is)/sog/lat/long/cog/true heading/time stamp and a bunch of other shit adding up to 168 characters Share this post Link to post Share on other sites

My guess is that there is a problem with the 'flip-up' system of the rudder in question, ie. he hit a ufo, took the rudder out and the force of the impact also broke the mount. I think its a lot more complicated than just dropping a new rudder in, even if he is carrying one onboard (which face it, he would be). Share this post Link to post Share on other sites

If ATR is smoke and mirrors lying about rudder and ending racing like this is some Australian campaign, he’s going to lose his sponsor, lose the good will of French fans and respect of his peers.

Sat Phone Reception: Iridium new NEXT constellation of 66 LEO sats up as of last year so this edition best sat reception of any edition, particularly at high latitudes which are problematic Alternative Devices "Say a Garmin inReach or something similar."

No AIS PLB final contact as Kevin zipped up in raft trying to sleep waiting for daylight and JLC. So AIS PLB signal screened IF it was even turned on, him knowing that. Turned off he would have turned it ON close to planned daylight recovery . That wasn't necessary as JLC came early in the dark, guided by the strobe.

blunderfull 445 #6579 Posted December 2, 2020 For perspective on JLC’s seamanship on the KE rescue we were yakking about Rich Wilson & Steve Pettingill’s 1990 rescue off the Horn which was a nighttime event too. JLC’s solo effort all the more remarkable. ”We do this now.” Legend. “He and one shipmate would tackle the clipper ship record set by Northern Light in 1853 during the Gold Rush from San Francisco to Boston by way of treacherous Cape Horn. They would be linked by newsletter and radiotelephone to schools during the 15,000-mile non-stop voyage. Their voyage around Cape Horn would become part of maritime lore. Four hundred miles short of Cape Horn, driving under bare poles for three days in seas that built to 65 feet (official estimate), the 60′ trimaran Great American capsized on Thanksgiving Day. In a first in recorded maritime history, the massive trimaran was then thrown upright by the sea an hour later. Seventeen hours later, in a dramatic midnight rescue, the giant containership New Zealand Pacific rescued Rich and shipmate Steve Pettengill.” Miracles happen.

Very cool. I had a look at Brit PM Johnson's Twitter feed to see if Alex had received something similar. No such luck....so the Brits have disowned him and regard him as German....but there is nothing from Merkel either? Alex it seems is now a national orphan. Maybe AT is not the first VG orphan in the eyes of their national leader??? The question is did the 1st American to finish the VG in the 2004 edition in a boat called 'Ocean Planet' recieve a Presidential telegram from George Jnr?? All the more notable because of Mike Plants tragic 'no start' in the edition before. Now maybe a GOP President from the fossil fuel energy rich state of Texas thought to himself, 'fuck this bloke', when he saw the environmental energy 'strap lines' attached to this Americans choice of boat name?? I might have to research that. I might be wrong but I think 'Ocean Planet' was the first VG boat christened with the environment in mind? Next edition in 2008 there was a handfull and it has consolidated ever since as a source of sponsor funding to get more boats to the VG start line. Ironically the 2008 race started on the first weekend in November after US election day. That was when the GOP's candidate and his loopy running mate from Alaska were kicked to the kerb by voters in favour of a more earthly party and more earthly coloured leader. You can never seperate politics and the VG. Share this post Link to post Share on other sites

shanghaisailor 1,220 #6583 Posted December 2, 2020 8 hours ago, Corryvreckan said: Ha - now I've gone and wasted an hour goofing off watching old VOR videos! You're right that the VOR footage was awesome, and the tech to make yacht racing a spectator sport has increased dramatically. I remember an old America's cup that was just helicopter footage of two sailboats going in a straight line. So when the 2000(or thereabouts) AC put cameras on the boats, it was much more engaging. But (and forgive me if this might seem like I'm moving the goalposts), even the best sailing footage is hard for a general audience to understand just by watching it. It's not that people couldn't understand sailing - Cricket and the NFL draw huge audiences, and they're nigh-incomprehensible. It's probably just a matter of critical mass - cricket and NFL fans learned it at the knee of Dads who were fans. Sailing is way behind that curve, outside of places like France. Even with the new video tech, it's likely going to be a long slow process to engage more non-sailing spectators. Like Rafael said upthread, everyone has a car, and can understand an F1 crashing into a wall and exploding into flame. I rewatched the Vestas grounding and I suspect that most non-sailors would just see a bunch of guys stumbling around in the dark and swearing. The boat accident that did make the news this week was Florida Man here. Not a story of great seamanship, but the picture is dramatic. PS. I haven't been to the W coast of Scotland (yet). I chose the name after a very nice single malt that I can only afford to drink on special occasions. Sorry about that. I must admit I am a bit of an anorak and have all the Whitbread/VOR official videos on disk. I use bits of them when i am called on to do presentations here in China to help grow our sport here but it is incredible how the quality of the footage has improved over the years. Careful, people go to to the West Coast of Scotland in their boat for a fortnight and stay for years. Even Princess Anne had Blue Doublet 4 or 5 moorings down the trot from us at Ardfern. If you were drinking a malt as 'special' as Corryvrekan it was surely a very fine malt indeed. Islay is my favourite. I remember once sailing down there, headed towards the shore using Lagavulin as a navigation point (I kid you not), anchored 400m beyond Ardbeg on golden sand in 4m of water (no tidal height to worry about there) then a friend drove us past Laphroig (Prince Charles favourite apparently) and spent the afternoon at Bowmore drinking 18 year old (in bond) with the distillery manager who was a friend of a friend - heaven! Back on thread, i completely agree with you. What is needed alongside the coverage is a good commentary which explains what is happening in a non-condescending manner. Those who stand out n my memory are the likes of Bob Fisher, obviously the likes of Peter Montgomery who has been called the voice of the America's Cup, the chap who commentates the start of the Sydney Hobart (he will curse me for forgetting his name. I was also impressed by the calm way Ken Read described the action during the San Francisco AC. Having said all that, there are experienced racers who don't seem to understand all the nuances of the racing rules so perhaps a long journey ahead to bring it to the masses. 6 hours ago, jack_sparrow said: AIS PLB has Sat GPS no different than EPIRB's.

It is a moot point because the reception by the rescuing craft is entirely ultimately dependant on the propagation of a (weak) VHF signal and the reception of that VHF signal by rescue craft and a big wave will reduce that effectiveness whether it is an AIS PLB or an AIS Personal Beacon.

Kevin is obviously no fool, and his comment about 'inversion' from the foils is quite interesting. If I was on a foiler, I'd be somewhat obsessive about not slacking off on your hull inspection routine after this. We didn't see Imocas folding in half in the last race, what did we change? I am hoping the longer wave period in the SO would lessen this risk...but it's the southern ocean. Not a nice place to be testing hull integrity You get that impression from the interview with Vincent Riou (posted up thread). Has to have been something completely outside any modelling. Did wonder if PRB had any data from sensors which might help, but given the speed of the sinking and Kevin describing the electrics getting fried this seems unlikely.
