Well done... Thanks a lot for sharing. I really wish this helps you with your local businesses
Watching in 2021 still, it is very useful thank you Sir!
ammmmmmmmmmazing explanation love this video
outstanding! iam going through a course in the navy and this really helped!
Thanks for clarifying several difficult concepts.
Very good explanation. Thank you!
Perfect explanation, thanks sir
Thanks for the video, makes is much easier to understand
Thanks a lot...it took me 2 years to understand it all in school but this 20 min video cleared it in just a go. Thanks a lot!!
A very good explanation.......a very good job
Excellent sir... Concept cleared.
Nice job. Stability made easy. Thank you
Interesting point not named is that the center of bouancy is the center of gravity of the missing water in the shape of the displaced part.
excellent video. very helpful!
Binance's CEO bares all about future developments in an exclusive interview
In the case of a sailing ship with an angle of heel of 20 degrees, would the metacenter be still called as such or would its name be changed? I guess the metacenter's location would be located somewhere at the level of the masts so the "meta" prefix wouldnt make sense anymore. I might be wrong. Btw I think it's essential to locate the metacenter in a sailing ship in order to find its stabilizing point in case of a heel.
Good explanation
this video came on and I wasn't watching the screen. It sounded like Woody Harrelson was giving the presentation *yesssss
Cheers from Malaysia
Awesome thank you
Does a boat or ship lower in the water if cargo is added to it? E.g., is a ship more likely to run aground in shallower water if it has cargo or if it doesn't? I've tried researching displacement and understand that the boat forces the water away from it but am confused whether cargo impacts the depth of the ship any.
Yes more cargo, more mass, bigger force of gravity
Thumbs up if you are from Strathclyde Uni
Never mind...
Sir please make videos on simpsons rule
It is so sad that it is simply wrong.
why is that?
Excellent. Slow and steady explanation without the jargon even a child can understand.
So....If the Ship condition is Even Keel and Steady, what is an again used the correction to know the real Displacement ?
Very well presented. Thank you!
Thanks , easy to follow
so clever, the best and simpliest explanation ever for this topic. Thank you !!! (even 11 years later 😉)
Missed a week of school and this just saved me, thank you!
This is exactly how a teacher should present things - step by step and with detailed explanations of all the important concepts.
Thanks a lot! ♫
Thanks! so easy to understand!
I'm going over stability and buoyancy right now, this video was very helpful. Thank you for the easy breakdown of the subject.
Good explanation... This will help help to my board exam as a deck officer i hope you cn post more video regarding navigation and trim and stability thank you so much
I have been trying to wrap my head around how buoyancy works for many years now. You were able to in just a few seconds help me understand it. Thank you for being awesome.
Shout out from Melbourne Australia
Ben Tv Howman @you are dumb then
And you're a fuckin' asshole for saying that.
Thank You so much. You saved my day
Interesting and relatively straight forward. However I suspect the determination of the center of buoyancy and the center of gravity for any given vessel is the challenging part!
The best I've seen on the topic. I've seen animated ones that are graphically more sophisticated, but with horrible robot voice overs that are too off-putting to listen to. Thank you. Going on to part two now.
That sinking feeling when your righting arm becomes a wronging arm :/
This comment for u sir love you so much 💖 it consumes my total tym to understand this topic but 20 mins ....No words salute sir ☺️
Oh my goodness this helps me understand buoyancy SO MUCH BETTER
Thank you sir
Beautifully explained ! Step by step , detailed and illustrative 🙏 thank you very much 🙏 God bless you 🙏
Thank you sir. It's so helpful for my Artificer class II examination.
Now... i can design a maximum Stability Warship.
and Finally gets the Feature and meaning of "Unsinkable"
Thanks Ben, great explanation, much better than reading a book.
Very well explained. Thank you very much for the knowledge!
Great explanation sir!! You make things easy to understand. Thanks!!
After so many times that i bumped thru the years into this thematic, this is the first time that i really understood. Nice explanation
Thank you so much !!! Regards from Malaysia 🇲🇾
Thanks for the detailed and understandable explanation. Does the gravitation force on the keel affect stability? Or is that force included in the placement of the center of gravity?
Its included in the placement of of the center of gravity, but with a heavy Keel you will probably have a lower center of gravity that affects stability in a Good way.
Thanks a lot sir, your video is very informative and it helps me in my lessons.
you explained it 10 x better than my Captain/Lecturer thank you very much Sir !

Is Center of Bouncy the same as "metacentric height?
pretty good explanation. it made al easy tô undestand. Thanks Capt.
thank you for the lesson, i understand you very well!
If you can help with this issue, thank you in advance. vessel with displacement 19130t KG = 7.01m wants to unload cargo of 170 t located 6.5 sea side from centerline and Kg of cargo 12.4m. Ship is not angled on either side at this time. Wants to unload and load back cargo with heavy lift crane with KG of crane 30 m and 15m from center line. KM for 19130 is 8.47m and for 18960 8.456m. We need all the MG shifts and all the angles before during after loading and unloading of this one cargo. The problem I am facing is that when cargo returns back to original position I do not get angles canceling out 0°. Thank you!
Best and simplest explanation of this nightmare! Thank you so much.
Thank you so much. An invaluable lesson made easy.

Thank you brother I got to class late last week and missed the lecture on stability now I know what he means about the righting lever
how does a weighted keel influence this equation? I know the COB will still move as the boat heels but if you had two identical hulls one with keel and one without would it change how proportionally the COB will move or how much movement you get of the COB to the degree of the heel? if you have both hulls at 20 degrees of heel would the boat with keel COB shift less?
Thank you, thank you very much. I have a search and I hope you can help me with some references, steps and necessary steps.

This is title of my research
Pedant alert: The phrase “That being said” should be followed with a contrary remark, not an affirmation.
Excellent explanation thank you!
Thank you I understand now how it works
Helpful Explanation, thank you very much!
You make this easier to understand. thank you very much!
help me 😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭
Thank you. Simple and straightforward. I like simple :)
Centre of Gravity is like balancing this pen? How do you calculate its position in the vessel??
Good explanation... This will help help to my board exam as a deck officer i hope you cn post more video regarding navigation and trim and stability thank you so much
Thanks for the great video Stanley 📹😀👍
Very helpful… thanks… I am trying to calculate for steel barges
Shouldn't that be "center of mass", rather than center of gravity?
Awesome explanation, thanks.
nice video, thanks,,,
Thanks a lot,sir!
an illustration of the point where the righting arm begins to shrink would help me
when the angle of heel is more than 8 degrees, the metacentre is no longer on the hull centreline ...
Fantastic exactly how my favorite tutor taught us stability at my skippers ticket course
Good explanation.
awesome, thanks!
Usually, Control Engineers desire which kind of output response ?
A) Under damped
B) Undamped
C) Critically damped
D) Over damped
Depends on the system. For a passenger boat, I would say critically to over damped, for a speed boat slightly underdamped.
amazing explanation! thank you very much!
Thank you. Your video was very intelligible :)
This is dope
I understand this.WOW.Thanks from Australia.
excellent
A unique take on a From the Depths tutorial, I like it!
Excellent Sir. Thankyu😊.
Thank you very much... Very helpful for cadets..
Thanks!
Refreshing...
I'm almost forget it...
Thanks...
Thank you so much...I got it..now its very easy for me...
This is so good. Thank you!!!
So my gf is not allowed on board your saying?
Very well explained. Thank you!
"Force of gravity" my ass, it's called weight.
There is no weight without gravity.... you meant mass?
Nice and easy explanation..Tks V mch.
