The first thing that most will notice about Ulstein's AX104 vessel Bourbon Orca is the new hull shape. The bow is the reverse of a conventional bow, something that Ulstein calls its X-Bow, which was developed by Ulstein Design. Ulstein believes that the new bow will offer improved sea-keeping and hence reduce noise and vibration. Model tests have also shown that it is faster and more economical in high waves.
