Great Video.Thanks. What are the causes of a negative GM? Improper ballasting or cargo loading or free surface effect? With the inclining experiment we find the GM of a lightship, from this GM (assuming that it's positive),how do we reach a stage where the GM is negative?
Anything that raises G has the potential to create negative GM. Some possibilities are loading cargo above G, taking water on deck, water being trapped during firefighting, lifting a load with a ship's crane (remember that the moment the weight is lifted the weight shifts to the head block).
MMADeckPrep Great video, I teach stability in Eastern Canada. I was just wondering what program you use to create these excellent animations? Keep the videos coming.
Thanks for the vid! Btw, your M seems never to be connected to B, neither by the vector arm nor by staying vertically above B, which ruins the whole concept of it.
Thanks for your question. Loll only happens when G is above M. The high G is what causes the Loll. If G is at or below M there will not be Loll. Because G is above M the vessel will not stay upright but will flop equally to either side. You can see another explanation of Loll here: ruclips.net/video/3ha0o13krI8/видео.html
Great explanation sir! Helped me with my competency exams. Thanks!

i think loading cargo on the deck like wood could rise G and cause angle of loll ??

why would the GZ be zero at the angle of loll?
why wud G b so high with a loll
