Bulbous Bow Function, Advantages, Uses and Location



                  Bulbous bow is a projecting globule situated at the bow of a ship just underneath the waterline. Bulbous bow  reduce the hull wave making resistance of a ship, which is the major residuary frictional resistance of the ship.

                      When the water is cut by the bulbous bow mainly, two type of waves  are formed ; primary wave and secondary wave. The primary wave  formed by the bow, just in front of the bow  cuts the secondary wave formed by the ship hull, thereby reducing dragging.


Advantages
> Increase propelsion efficiency
> Increase fuel efficiency
> Increase ship speed
> Increase stability
> Reduce dragging
> Reduce fuel consumption 
> Reduce pitching
> Act as BUMPER in collision.
