Explain bilging of empty double bottom or deep tank in ships below the waterline leads to increase in GM?
Rksuswal
It is as good as adding weight below waterline. So the center of gravity will move towards the keel and the GM will increase as KM-KG=GM. It may be subjected to Free surface correction till it gets filled up finally. Till then the GM loss may be experienced. Captain PK JAIN It is as good as adding weight below waterline.
