I just realised people posting comments not familiar with the RNLI in the UK are assuming this is a lifeboat... as in the kind of lifeboat attached to cruise ships that are lowered into the sea in an emergency. This is a rapid rescue boat that has a trained crew onboard that responds to ships/persons at sea in distress and is launched from a station or dock/marina on the coast. RNLI and HM Coastguard work together with help from Royal Navy and other military when necessary e.g. helicopter search and rescue.
The "lifeboats" attached to cruise ships, etc are technically known as "Totally Enclosed Survival Craft" - I trained as a coxswain for them when I worked in the North Sea oil and gas industry.
Quick note to Mr Chickeneater. Actually, Sir most of our crewmen and women are volunteers. But STILL we, the RNLI, get no government funding. Thanks for your contribution to this debate. It all helps to keep us in the public eye.
These boats are amazing and the people that go out on the ocean to rescue people are just as amazing for the job they do. Thank god we have people like this around!
This is so impressive - I think the world of these life boat people - they are simply amazing what they do - So thank you old Seadog for a great video !!
I think it was filmed inside many years ago for the BBC tv series 'blue peter ' where presenter john noakes was strapped into a seat and the vessel was inverted...this was in the 1970s as I recall with none of today's risk assessment health and safety red tape
I don't know whats more impressive: That the thing just refused to stay upside down (which is a good thing), or how readily it was able to float on its cabin for the moments it actually WAS upside down.
@@robertcaron9181 The all weather lifeboats are designed with large and heavy items placed as low as possible in them and the wheelhouse the orange thing on top of it all where the crew are is designed to be very buoyant which helps it return to an upright position I hope that's makes sense and is simple enough the RNLI have a video on it here: th-cam.com/video/23J6zU-aQZk/w-d-xo.html
Just an indication how stable these vessels are, shes layed over more than 170 degrees and still needed to be pulled more in order to make a complete roll, safest boat in the world is the one that comes back to the upright after capsizing.
I knew of such tests, but had never seen one. Surprised me a bit it did not go further into the water, then realized that sealed cabin must be really buoyant. Performed as it was supposed to, and is a really nice looker - I would love to own one.
Rick Davis I'm not an expert, but it could be a lot of reasons. Like if there are crew members on the outside of the boat, they would get thrown into the water and would be in danger of hitting the props.
I was sunning myself on the beach of Porthdinllaen on the Llyn Peninsula, back in June 2023, is the stunning weather. Once of the most picturesque beaches in the whole of Gwynedd, i didn't realise they had a Shannon moored nearby.
Do they do a drop test of any kind? Like if they came of the top of a large wave crest and dropped to the trough? Still curious about the buoyancy of ot were flooded or swamped multiple times with doors open or if windows were damaged...
That is one serious craft, I take it she is self righting, she's even beautiful just to look at her, look after your craft & your craft will look after you, many thanks for psting,
Did you expect anything less from the RNLI. We are acknowledged world wide as being the finest marine rescue organisation on earth. Our personnel are available 24/7 to rescue anyone, from a lone swimmer or sailor to an ocean liner. We operate both on british coastlines, in land rivers, such as the Thames, and even further afield when needed. The RNLI also have specialist vehicles such as hovercraft , for mud flat rescues, mainly around the east coast. Additionally we , on occasion assist in the rescue of residents in flooded areas. So, naturally, our personal have the very best technology that money can buy. This obviously costs a great deal of money. RNLI receive no subsidies or Grant's from the government. Rather, we rely upon the generosity of private individuals such as yourself. So next time you see a collecting box, maybe on the bar of your local pub, please spare as much as you can afford, to enable us to maintain this world beating service. You never know, one day you may find yourself in need of our services. But don't worry. We are there for you.
That's amazing... That must be positive stability up to a heel of 160° or something ridiculous like that... O.o That boat really doesn't want to stay upside-down.
And fitted with H4 rope cutters from Plymouth, well, made in Perth but supplied to the RNLI from just outside Plymouth. You can't quite see them in the video...
Those really awesome amazing boats I remember one sank around Christmas time in the 80s I think they were trying to save I do his wife and their daughter off of brand-new ship best I remember
It was agonizing to watch with how long the vessel took to be capsized. Those life boats really don't want to be rolled over. If I have a pleasure vessel built I want it built to these standards.
I was there that day watching this from the Devon Samson (that's the floating crane) I was part of a fire crew when she was in use, I was actually trying to spot myself lol but think I was watching it through the cabin window 👍
I presume these are crewed by about 4-6 volunteers (some 500kg or so). How does the self-righting go if those volunteers have been tossed when the boat is inverted onto the now ceiling of the cabin which is now down the bottom. Just curious.
I have seen several video's exactly like this showing the righting test of these boats. I am a skipper for the Australian Volunteer Coast Guard here in Melbourne Australia and I would love to have one of these boats stationed here as they are fantastic but alas our government won't coff up the money for decent boats...
Guess what. The UK government didn’t cough up a penny either. That’s not a coast guard vessel. That’s from the Royal National Lifeboat Institute. Funded entirely by donations from the public.
Had a friend who bought an old life boat. The totally sealed ones. It had a pretty deep keel and 400 lbs in the bottom of it. It was supposed to right itself. Hopefully he never had to find out. The thing only did 6knots. He could only leave at slack tide.
I assumed that the RNLI tested one of each type of self righting boat but every boat that is self righting has the same test. They could be made to right more quickly but would injure the crew on board, so they had to be slowed down!!!
You know how people want land rovers to go off road ! Well I want one of these boats now !! but what about all the diesel fuel dont they have air vents that on a normal boat would take on water? I bet its all covered but I love all the details. I enjoyed seeing that thank you.
In the event of a roll over the engines shut down, and I suppose the engineers have designed a water trap to keep water out the intakes. And I wonder how bad the storm would be if you did manage to roll it :-o
OK, but what about the diesel engines, oil in the crankcase spilling into the cylinder head along with flooded type battery banks etc.? My sailboat is balusted and will right itself too but a lot of stuff is not going to be Ok.
It looks "uneven" to me. I'm looking at the displacement and, to me, it appears that she sits lower in the water with the hull down than with the superstructure down. I would think with a smaller superstructure than hull. she would have been further underwater when upside down. Just a landlubbers observation.🤔🤗
The displacement volume will be the same, obviously it has to be, but I think it appears that way because the maximum draft of parts below the water is greater when it’s upside down. I.e. the super structure is taller than the hull is deep. It’s very weird seeing the deck out of the water whichever way up it is.
Hehe you should check out the RNLI Ribs. The Atlantic 75 i know can float and hold 15+ people with all the sponsons entirely deflated. I think the 85 can do the same. There all equip with self righting systems aswell which is amazing to watch.
I had read that none of the RNLI lifeboats re-right themselves, but this looks to me like they do. Anyone "in the know" want to clarify please? I just applied for a posting at Seahouses and am curious (if they don't it wouldn't change my mind!)
Hi Robert, I was an RNLI crewman for 10years. All our boats are self righting. Most are now made in Poole. If you join you'll go there for training. cheers, Barry.
I didn't get it :-( I'm a US citizen and a retired US Coast Guard Surfman. I applied for the Seahouses posting and was told I had been shortlisted for an interview and was VERY excited. Unfortunately the RNLI doesn't sponsor people applying for postings so they can get a visa, so I got disqualified. Super bummed :-(
Robert Mantell the inshore lifeboats aren't automatically self righting, they have to be activated by the crew, or the crew will manually right the boat themselves. All weather lifeboats like the one in the video are automatically self righting though.
RNLI All weather lifeboats have been built to be able to sefl right by design for years. Campbeltown's previous lifeboat was the Arun class and she could self right and I think she arrived there in the late 70's. Not sure if Arun was the first class that was designed this way though.
All offshore RNLI boats are self righting. Some of the inshore ribs have an inflatable balloon that can be activated in the event of a roll to right the vessel.
WOW...now thats the kind of boat I want...but why no cams inside..? I wanted to see if water was coming in through the windows...This kind of test should be done on all boats not just lifeboats
It is a very nice hull design that fits a particular purpose. However while I do like the two compromise tunnels for the propellers, I am a little reluctant to accept the working of those rudders as the side step due to the tunnel will restrict the rudder turning effect. What I would have done is to cut the corners on either side of the rudder at the transom such that a VEE is formed at the back but a step truncation will be included at the beginning of the VEE so that the water will start separating easily somewhere in line with the stock of the rudder. There is no harm if the VEE is aerated as the inertia of the water behind the propeller will retain enough hard solid water on either side of the propeller. This side Vee on either side of the rudder stock will permit more volume of water to be thrown sideways by the rudder to increase pressure on one side and a lower pressure on the other side, hence the side step will be non existent. In order not to lose the planing area due to the side vee at the back , a plate may be added which is in the plane of the bottom or else the trim tabs could be inserted a little forward to see to this plate effect in addition to trimming the boat while the rudder will be happier throwing more effective water sideways. This in addition to the bow thruster would would make that hull rotate on a sixpence or should I say a cent!
@@alanj9391 You are assuming what you said, as you do not know me enough, nor my relationship with boats. I studied at the University of Newcastle upon Tyne, obtaining the highest qualifications, served my six years apprenticeship and worked for 15 years with the Royal Navy at Chatham Dockyard, I am a boat designer and a boat builder up to 40 feet at 40 knots, and my family has been building boats since 1708. Please review what I said and check the dynamics and logic which I suggested. Also, note that I designed better high-speed rudders and propellers than those used on this craft. Please do check my background knowledge on boats during the last 84 years.
Did you know that the knights templars had ships that could re right themselves . And they worked in the same principle as the life boat does The templars used them to get to France for the crusades, and they had to invent something like this to move large amounts of men across open water to protect them so they could fight . The templars were very advanced and they mapped the world by creating these unsinkable ships The templars actually traveled to America by unsinkable ship and mapped America well before Columbus . Templar ships were many and they held 100 men each It is nice these boats exist , it is the least a life saver deserves for their troubles helping others .
Basically the entire boat is watertight, trapping air inside the cabin, while heavier items such as engines and fuel tanks are in the bottom which helps pull it back upright.
Alterra, the most advanced race in the galaxy, with devices that can create ships from thin air--their lifepods capsize and sink Earth: technologically underdeveloped, lifeboat doesn't sink
This is absolutely beautiful? I've actually seen this but had been told they could do this? Being an Ex-Fisherman on trawler,s, I love these women and men? They really have saved so many live,s? I love you all, Jesus be with you all Amen Selah X ❤️

What I would have done is to cut the corners on either side of the rudder at the transom such that a VEE is formed at the back but a step truncation will be included at the beginning of the VEE so that the water will start separating easily somewhere in line with the stock of the rudder. There is no harm if the VEE is aerated as the inertia of the water behind the propeller will retain enough hard solid water on either side of the propeller. This side Vee on either side of the rudder stock will permit more volume of water to be thrown sideways by the rudder to increase pressure on one side and a lower pressure on the other side, hence the side step will be non existent. In order not to lose the planing area due to the side vee at the back , a plate may be added which is in the plane of the bottom or else the trim tabs could be inserted a little forward to see to this plate effect in addition to trimming the boat while the rudder will be happier throwing more effective water sideways. This in addition to the bow thruster would would make that hull rotate on a sixpence or should I say a cent!
Fortunately the RNLI knows better than you do about designing lifeboats.
@@alanj9391 You are assuming what you said, as you do not know me enough, nor my relationship with boats. I studied at the University of Newcastle upon Tyne, obtaining the highest qualifications, served my six years apprenticeship and worked for 15 years with the Royal Navy at Chatham Dockyard, I am a boat designer and a boat builder up to 40 feet at 40 knots, and my family has been building boats since 1708. Please review what I said and check the dynamics and logic which I suggested. Also, note that I designed better high-speed rudders and propellers than those used on this craft. Please do check my background knowledge on boats during the last 84 years.
Hull is designed just in case it runs aground it won't tip over believe me I used to lift them and block them off
This is the lifeboat getting tested to see it will self right
I wonder how well it did about keeping water out of the cabin
The cabin is designed to be watertight, otherwise the self-righting wouldn’t work
We all live on an orange submarine
Shut up Carl.
Did you know that the knights templars had ships that could re right themselves .
And they worked in the same principle as the life boat does
The templars used them to get to France for the crusades, and they had to invent something like this to move large amounts of men across open water to protect them so they could fight .
The templars were very advanced and they mapped the world by creating these unsinkable ships
The templars actually traveled to America by unsinkable ship and mapped America well before Columbus .
Templar ships were many and they held 100 men each
It is nice these boats exist , it is the least a life saver deserves for their troubles helping others .
Looks promising.
Promising?
So no explanation of how it was righted? K, didn't want to learn anything today anyway.

One of the boat's builders explains how it works - th-cam.com/video/23J6zU-aQZk/w-d-xo.html :)
Basically the entire boat is watertight, trapping air inside the cabin, while heavier items such as engines and fuel tanks are in the bottom which helps pull it back upright.
Alterra, the most advanced race in the galaxy, with devices that can create ships from thin air--their lifepods capsize and sink
Earth: technologically underdeveloped, lifeboat doesn't sink
Good stuff!
This is absolutely beautiful? I've actually seen this but had been told they could do this? Being an Ex-Fisherman on trawler,s, I love these women and men? They really have saved so many live,s? I love you all, Jesus be with you all Amen Selah X ❤️
Great boat..
Interesting! Nice watching at 2 x speed ☺️
That's a Tamar class lifeboat btw. Number 16 on the hull tells you
I''l bet there were a few people holding there breath!
Go on youtube and see him go down the brand new slipway
