I've done quite a few ocean crossings on a sailboat and we have one of these mounted below deck by the hatch/entrance, ready to grab and go if things go to shit. We also have an EPIRB (emergency position-indicating radio beacon) with GPS mounted by the helm with a hydrostatic release, so -- if we are not able -- it (hopefully) can release and activate automatically if it becomes submerged. This is also the case for the life rafts. As Casual Navigation and several others have mentioned in this thread though, you should never rely on only one piece of safety equipment, so remember to check your flares, immersion suit, light beacons, flashlights, fire extinguishers/blankets, handheld VHF, satphone, InReach, etc., keep everything up to date and know where it is stored/placed on the ship. You never know when chaos strikes, and it can/will be when you least expect it. We got hit broadside and knocked down by a sudden huge wave in pitch darkness on a otherwise smooth moonless night, and we were very lucky that we didn't lose the mast, sails or get a man overboard situation (knock on wood). One thing that really becomes clear when you are out at sea, is how unfathomably huge it is. You can go many days even in high traffic lanes over the Atlantic during prime season and not see any other ship. You can truly be very, very alone, and Mr. Davy Jones is the last guy you want to visit. ;) Lastly, huge kudos to Casual for these videoes. This channel has some of the best maritime content on YT. Thanks!
Fell in love with this channel! I am a Service Engineer and go aboard ships to service/install communications and navigation equipment, and it is refreshing to see someone so dedicated who explains and illustrates so effectively! Thanks mate! Subscribed obviously :)
I wonder if it would be at all cost-effective to mount half a disco ball on a free-rotating or crank-driven mount on a lifeboat's roof or if that would be silly
Dammit, those marine types really have nice toys. Us aviation guys do not have something like a SART, we have to do with normal ELTs or PLBs, Emergency Locator Transmitters or Personal Locator Beacons, transmitting on 121.5 MHz (including two way AM communication in some installations) and 406 MHz for CORPAS-SARSAT reception. No radar active beacons though, those are only used in normal operation (Mode-S secondary radar transmission). The 121.5 ELT signals are picked up quite often to be honest, we usually keep listening watch on that frequency.
Can't put a price on safety. They are expensive because the research and high quality durability of the device. It has to endure seawater which if you own a vessel in saltwater, the corrosive characteristics of the saltwater are very much known. 😟 plus the device has to be reliable and work when needed.
So testing actually transmits. Is there something to signify to someone that it is only a test or does someone sitting at a radar screen just wait anxiously to see if the signal keeps repeating?
If i recall correctly you're meant to do it within the first 5 minutes of a new hour and to only test it for 30 seconds or so. But without looking it up again i'm not sure
A ship normaly carries a few. You don't carry peosonal ones as it is important to only activate them one at a time to avoid interference with eachother
can i ask u a doubt i have question while i writing a exam can u give a correct ans for this question ; the switch on the search and rescue radar locating device can be changed to postions? the options are a] on and off b] on and off and test c] on and off and test and transmit d] on and off and transmit can u tell the answer
Hey@@CasualNavigation you gotta watch this; scitechdaily.com/new-mit-search-and-rescue-algorithm-identifies-hidden-traps-in-ocean-waters/ The whole thing isn't quite ready yet, but holy shit... This is the biggest game changer since Matthew FONTAINE MAURY... 😲😲😲🤯
I have no intention of ever being at sea, and while you never know where life will take you, it doesn’t look likely. And yet I can’t get enough of this channel since I found it a few days ago. Go figure!! It’s nice to learn safety stuff for situations you’ll probably never be in. It’s no substitute for training but you never know what might stick and come in handy.
This is basically how radar jamming works, except here it's used to get the emitting radar's attention rather than conceal the exact position of the jammer.
Hi, I love your videos and they are invaluable when I go for exams, is there any way you could do a brief video on the ISM code and SMS (Safety Management Systems)?
Everything you explained is correct, however at the end, in between the sart and flares, comes the use of the mandatory gmdss vhf. But you are the closest one i've seen so far. You might be a candidate to explain the cospas-sarsat in a proper way.
I do have patreon: www.patreon.com/CasualNavigation It would be amazing to have your support, but please don't feel you need to. I enjoy making the videos so they will still continue regardless.
Why don't they make satellite transponders?, 40nm is not much for a vast ocean. But if your doodad has a GPS receiver and a sat transmission it can instantly broadcast your location to the rescuers. Plus sat coverage in open sea is no problem. You could even combine both systems for close/long range
There are satellite-connected devices for emergency situations - I'm more of a satellite guy than a maritime guy, but try looking up GMDSS. The main downside of satellite connectivity is cost: even simple GPS transponders can be a few hundred dollars, though in some cases they're required by law. Another interesting benefit of satellite systems is satellite imaging: there are now enough imaging satellites to get pictures of the entire surface of the Earth every 24 hours or less, with at least 2-meter resolution. Radar satellites, while less common, can see through clouds and in darkness. Since these satellite operators generally provide information for free in emergencies, they could also be of use in a search and rescue scenario.
I'm a big fan of you, man you-re videos are really helful to me. Please make some MARPOL 73/78 explaining videos when you have time. Keep up the good work !
Hello. That was a very nice video covered everything but can you please clarify if the SART is tested on board will it still show 12 concentric circles or 11 ? Since the closest line should be the position of SART and that is actually just very close to Radar(even if tested in forward part of ship) ? Thanks
Are SARTs (or the signals from them) a distress signal by themselves? Looking at the International code of signals, chapter 4 section 1 i found no reference to SARTs
I have idea like: making alot of small one like at each seat, then this one to be supported by each person have extra battery, maybe imagine land on island with fruits and still alive. The radar is to be detected by a satellite or walkie talkie? Of a walkie talkie waterproof(silicone/nano spray) 5km or more type? Then all rescuers when at sea area to have the walkie talkie switched on with batteries. But i heard that theres no such rescuer and are cannibals for now and asking for help is bad luck(will be eaten)?
