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.
