What causes a ship to ride lower in the water and limit its speed?

[Rothiemurchus]

A few years ago the passenger ship QE2 ran aground off the East coast of America.The ship was traveling too fast and rode low in the water.
Was this due to the Bernouilli principle? And can it happen to ships in deep and shallow water?

not the Bernouilli principle
waves
bow and stern waves [wake] and resulting hollow at the midships point
causes a very fast moving ship to ride lower in the water then its static
water line depth
this allso limits the speed of nonplaning ships to 1.34 times the square root of the water line know as hull speed
