Scaling. Water drag goes as the area, but inertia (mass) goes as the volume. The volume to area ratio of an object of given shape increases in proportion to its length.

Because the kinetic energy of the vessel is so enormous, it takes a long time to dissipate it. Don`t forget that the kinetic energy is 1/2 m v^2, and with a vessel weighing in excess of 1/4 million tons, that is a lot of energy.

Big Mo........
Momentum.
** I will say it again, MOMENTUM-
DEF-Also called linear momentum. Mechanics. a quantity expressing the motion of a body or system, equal to the product of the mass of a body and its velocity, and for a system equal to the vector sum of the products of mass and velocity of each particle in the system.
MO=MV
KE=(.5M)V^2
Mass is a much larger factor in Momentum than KE.
