The X bow hull design ships provides smoother movement of the ship with less slamming, which also makes living and working environment on the vessel better and reduces the chances of cargo shifting. According to a study, X bow design reduces the movement of the ship by almost 20% even in the roughest seas. A ship with an X bow design can thus easily sail through heavy waves with better speed and less movement. Opinions taken from seafarers who have worked with X Bow reflect much better living and operating conditions. Some of the officer even mentioned that unlike in ships with conventional bows, speed in X bow ships didn’t require to be reduced when facing rough sea weather.
