History and facts

The X-BOW® hull line design is one of ULSTEIN's main contributions to marine history. ​The concept was launched in 2005. Today, more than 100 vessels have been built.

KEY BENEFITS:

Power efficiency:

The bow shape reduces pitch/heave accelerations and speed loss in waves, which renders higher transit speed or reduced power consumption possible. This improves fuel efficiency and reduces emissions to air.

Comfort:

The bow shape eliminates slamming and bow impact, thereby reducing noise and vibration. This leads to a more comfortable workplace and more effective rest time for the crew.

Safety:

The bow shape gives a soft entry in waves, thus reducing spray and icing. The likelihood of extreme weather damage to the forebody is reduced.
