SUMMARY

The discussion centers on the factors causing a ship, specifically the QE2, to ride lower in the water and limit its speed. It highlights that the phenomenon is not related to the Bernoulli principle but rather to the dynamics of bow and stern waves, which create a hollow at the midships point. This effect causes fast-moving ships to ride lower than their static waterline depth, thereby restricting their speed to a maximum of 1.34 times the square root of the waterline length, known as hull speed.

PREREQUISITES
  • Understanding of hydrodynamics and ship design
  • Knowledge of wave mechanics, specifically bow and stern waves
  • Familiarity with the concept of hull speed in naval architecture
  • Basic principles of fluid dynamics
NEXT STEPS
  • Research the principles of hydrodynamics in naval architecture
  • Study the effects of wave formation on ship stability and speed
  • Explore the calculations involved in determining hull speed
  • Investigate the impact of water depth on ship performance in both deep and shallow waters
USEFUL FOR

Naval architects, marine engineers, maritime students, and anyone interested in ship design and performance optimization.

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?
 
Physics news on Phys.org
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
