Content for Lake Superior State University (LSSU) course on Boat Handling and Navigation. Lectures by Captain Benjamin Hale, provided by Inland Seas Education Association.
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
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
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!
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!
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.
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.
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?
Excellent. Slow and steady explanation without the jargon even a child can understand.
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 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!!
Missed a week of school and this just saved me, thank you!
After so many times that i bumped thru the years into this thematic, this is the first time that i really understood. Nice explanation
I'm going over stability and buoyancy right now, this video was very helpful. Thank you for the easy breakdown of the subject.
Very well presented. Thank you!
Thanks , easy to follow
outstanding! iam going through a course in the navy and this really helped!
Thanks! so easy to understand!
Best and simplest explanation of this nightmare! Thank you so much.

Shout out from Melbourne Australia
Ben Tv Howman @you are dumb then
And you're a fuckin' asshole for saying that.
Beautifully explained ! Step by step , detailed and illustrative 🙏 thank you very much 🙏 God bless you 🙏
Thanks Ben, great explanation, much better than reading a book.
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
Very well explained. Thank you very much for the knowledge!
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
Oh my goodness this helps me understand buoyancy SO MUCH BETTER
Thank you sir
A very good explanation.......a very good job
Thanks for clarifying several difficult concepts.
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 ☺️
You make this easier to understand. thank you very much!
Fantastic exactly how my favorite tutor taught us stability at my skippers ticket course
Great explanation sir!! You make things easy to understand. Thanks!!
pretty good explanation. it made al easy tô undestand. Thanks Capt.
you explained it 10 x better than my Captain/Lecturer thank you very much Sir !
Clear and concise explanation....well done!
This is so good. Thank you!!!
A unique take on a From the Depths tutorial, I like it!
Well done... Thanks a lot for sharing. I really wish this helps you with your local businesses
Thank you so much !!! Regards from Malaysia 🇲🇾
Helpful Explanation, thank you very much!
Very good explanation. Thank you!
Thank you so much. An invaluable lesson made easy.
Nice job. Stability made easy. Thank you
Awesome explanation, thanks.
Thank you sir. It's so helpful for my Artificer class II examination.
I understand this.WOW.Thanks from Australia.
Nice presentation. Thank you mate !!!
thank you for the lesson, i understand you very well!
Excellent sir... Concept cleared.
Watching in 2021 still, it is very useful thank you Sir!
Nice and easy explanation..Tks V mch.
Thanks a lot sir, your video is very informative and it helps me in my lessons.
Thanks for the video, makes is much easier to understand
nice one...thanks
Excellent presentation, easy to digest.
ammmmmmmmmmazing explanation love this video
gud job....easy understanding
Thanks for the great video Stanley 📹😀👍
Refreshing...
I'm almost forget it...
Thanks...

Thank you I understand now how it works
Very helpful… thanks… I am trying to calculate for steel barges
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!
Cheers from Malaysia
Good explanation
Now... i can design a maximum Stability Warship.
and Finally gets the Feature and meaning of "Unsinkable"
nice video, thanks,,,
Excellent

is weight depends on center of gravity point?
thanks good stuff
very nice !
