X-Bow (Shipbuilding) (Paperback)

High Quality Content by WIKIPEDIA articles! The Ulstein X-bow is a new inverted ship's bow designed to improve handling in rough sea, and to lower fuel consumption by causing less hydrodynamic drag. It is shaped somewhat like a submarine's bow. The Bourbon Orca, design AX104 is an Ulstein A-Series Anchor Handling Tug Supply vessel, built for Bourbon Offshore Norway, and was the first ship built with the Ulstein X-bow. The bow is a nautical term that refers to the forward part of the hull of a ship or boat, the point that is most forward when the vessel is underway. Both of the adjectives fore and forward mean towards the bow. The other end of the boat is called the stern. The bow is designed to reduce the resistance of the hull cutting through water and should be tall enough to prevent water from easily washing over the top of it.
