Day Shapes
Day shapes are mast head signals visually indicating the status of a vessel to other vessels on navigable waters during daylight hours whether making-way, anchored, or aground. These signals consist of a set of simple geometric shapes—''ball'', ''cylinder'', ''cone'', and ''diamond''—that are displayed, hung from a mast, in a prescribed manner to indicate a vessel's operational status; some of these signals may be somewhat involved. The meanings of the shapes are defined by the International Regulations for Preventing Collisions at Sea (ColRegs). Day shapes are black in color and their sizes are determined by the ColRegs; for example, the size of the ball is not less than . The vertical distance between shapes is at least . Vessels of less than length may use shapes of smaller size commensurate with the size of the vessel. Day shapes of standard and reduced sizes are both commercially available. Day shapes are commonly constructed from a light weight frame covered with fab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime Flag Signalling
Maritime flag signalling, generally flaghoist signalling, is the principal means other than radio by which ships communicate to each other or to shore (distinguished from flags showing nationality, ownership, or (for naval vessels) organizational status). Virtually all signalling by non-naval vessels is now organized under the International Code of Signals (whether by flaghoist, semaphore, signal lamp, or other means), which specifies a standard set of flags and codes. Naval vessels generally use an extended set of flags and their own codes. This article will touch on the historical development of maritime flag signalling. Early developments In the early days of sail, the use of signals to communicate between ships was primitive, as seen by one admiral's instructions to his fleet in 1530: "Whensoever, and at all tymes the Admyrall doth shote of a pece of Ordnance, and set up his Banner of Council on Starrborde bottocke of his Shippe, everie shipps capten shall with spede g ...

International Regulations For Preventing Collisions At Sea
The International Regulations for Preventing Collisions at Sea 1972 (COLREGs) are published by the International Maritime Organization (IMO) and set out, among other things, the "rules of the road" or navigation rules to be followed by ships and other vessels at sea to prevent collisions between two or more vessels.''Convention on the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs)'' , from the IMO (The International Maritime Organisation). Retrieved 13 February 2006. COLREGs can also refer to the specific political line that divides |
