Coefficients of Fineness
A table of offsets, although accurately defining the hull shape, does not provide an immediate feel of the main characteristics of that shape. There are some “coefficients” which can be obtained for the underwater hull which provide clues as to its general nature and its likely behaviour.
BUOYANCY AND DISPLACEMENT
It was Archimedes who first realised, in his “eureka” moment, that a body that is immersed completely in water will displace a volume of water equal to the volume of the body and that the apparent weight of the body, when immersed, will be reduced by the weight of water displaced.
