On slower ships like tankers and barges, a fuller bow shape is used to maximise the volume of the ship for a given length. The bow may be reinforced to serve as an ice-breaker. [4] The forward part of the bow is called the "stem" or "forestem". Traditionally, the stem was a timber (or metal) post into which side planks (or plates) were joined.
A bulbous bow is a streamlined flaring or protruding bulb at the bow (or front) of a ship just below the waterline. The flare or bulb modifies the way the water flows around the hull , reducing drag and thus increasing speed, range, fuel efficiency , and stability.
The Ulstein X-Bow (or just X-BOW) is an inverted ship's bow designed by Ulstein Group to improve handling in rough seas, and to lower fuel consumption by causing less hydrodynamic drag. [1] It is shaped somewhat like a submarine's bow. [2] Bourbon Orca anchor tug, shown in 2012, was the first ship built with an Ulstein X-Bow in 2006.
The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft.
Comparison between an axe bow (442) and a conventional bow (441) The axe bow is a wave-piercing type of a ship's bow, characterised by a vertical stem and a relatively long and narrow entry (front hull). The forefoot is deep and the freeboard relatively high, with little flare, so that the bow profile resembles an axe.
This is a list of historical ship types, which includes any classification of ship that has ever been used, excluding smaller vessels considered to be boats. The classifications are not all mutually exclusive; a vessel may be both a full-rigged ship by description, and a collier or frigate by function. A two-masted schooner Aircraft Carrier
Two of Aurora Expeditions’ ships, the Greg Mortimer and Sylvia Earle, use a patented inverted bow, designed to slide gently through the waves, reducing impact and vibration and improving ...
Apart from improved hydrodynamics, the rounded bow shape also provided plenty of room for a very large sonar array above the torpedo tubes. Commissioned less than three months after the first Project 627, the USS Skipjack was the first combat vessel in the US Navy to use a "pure" teardrop hull since it was abandoned almost half a century earlier.
