Ship Motions
Ship motions are the six degrees of freedom that a ship, boat, or other watercraft can experience. Reference axes The '' vertical/Z axis'', or ''yaw axis'', is an imaginary line running vertically through the ship and through its centre of mass. A yaw motion is a side-to side movement of the bow and stern of the ship. The '' transverse/Y axis'', ''lateral axis'', or ''pitch axis'' is an imaginary line running horizontally across the ship and through the centre of mass. A pitch motion is an up-or-down movement of the bow and stern of the ship. The '' longitudinal/X axis'', or ''roll axis'', is an imaginary line running horizontally through the length of the ship, through its centre of mass, and parallel to the ''waterline''. A roll motion is a side-to-side or port-starboard tilting motion of the superstructure around this axis. Rotational There are three special axes in any ship, called longitudinal, transverse and vertical axes. The angular movements around them—a ...

Training Ship
A training ship is a ship used to train students as sailors. The term is mostly used to describe ships employed by navies to train future officers. Essentially there are two types: those used for training at sea and old hulks used to house classrooms. As with receiving ships or accommodation ships, which were often hulked warships in the 19th Century, when used to bear on their books the shore personnel of a naval station (as under section 87 of the Naval Discipline Act 1866 ( 29 & 30 Vict. c. 109), the provisions of the act only applied to officers and men of the Royal Navy borne on the books of a warship), that were generally replaced by shore facilities commissioned as stone frigates, most ''"Training Ships"'' of the British Sea Cadet Corps, by example, are shore facilities (although the corps has floating Training Ships also, including TS ''Royalist''). The hands-on aspect provided by sail training has also been used as a platform for everything from semesters at sea for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minelayer
A minelayer is any warship, submarine, military aircraft or land vehicle deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. An army's special-purpose combat engineering vehicles used to lay landmines are sometimes called "minelayers". Etymology Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term "mine layer" while the introduction speaks of the men assembled from the "mine planters". During and after that war the term "mine planter" became particularly associated with defensive coastal fortifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
