In detail if a line of buoyancy force is extended it will meet the line of gravitational force, this point of intersection is called as Metacenter.īut what if a ship has tilted to port or starboard side of the ship or in the aft and forward of the ship How do we show this stability of our ship in diagrams. Have a look at this image, it includes all the basic terms which are either responsible for ship stability or gets affected by it. Please remember ship displace different quantityvolume of water in fresh and sea water but the weight remains the same, coz both water are having different specific gravity(sea water of specific gravity sg 1.025 and fresh water of sg1.0).īecause of its complex shape and uneven weight distribution on a ship.

Therefore anybody to float the upward force or buoyancy should always be equal to or more than the weight of the body.Īnd here we got one more definition of Displacement of a ship.ĭisplacement: This is the equivalent mass of water displaced by the hull.

Whenever anybody thinks of ship their very first question regarding it will be how does this thing float There are a variety of ships ranging from very large crude carrier vessels to very small offshore support vessel.īut the basis of any ship(or any other object) floating on water is same.
