I would love to have an X-bow in SS. They behave very good in high seas and can go faster than ships with conventional bow in high seas. But if they take the waves in the side of the ship the x-bow is known to roll.
Here is a video of the X-bow Bourbon Orca passing two PSV/AHTS ,because of the X-bow the Bourbon Orca can go faster http://www.youtube.com/watch?v=Mqcpe5au_7M (http://www.youtube.com/watch?v=Mqcpe5au_7M)
