Consequently, the scale factor for the mass (M) and displacement is the same as that for the volumes, i.e.: S (M) = S 3 (L) = 25 3 = 15 625 Similitude of forces (F): If the external forces on the model are in similitude, like the shapes, masses and inertia, the model's movement will be in similitude. It can thus be shown that the forces (F ...
Ship models: This was a standard size for ship models produced by Revell and Italeri but they have moved from it. 1:700: 0.435 mm: Ship models: This is the scale that most manufacturer chose to produce the largest series of waterline plastic model ships and submarines. Full hull models are popular in that scale as well. 1:600: 0.508 mm: Ship models
These are typically built by commercial firms, or, in the past, model departments of large shipyards. One famous builder of ship models for the United States Navy was the firm of Gibbs & Cox; a 1/48 scale model of the USS Missouri, which is on display at the Washington Navy Yard museum, required an estimated 77,000 man hours to construct.

The rank flag or distinguishing flag is the flag worn by a superior officer on their flagship or headquarters (hence the term flagship). The origins of this are from the era before radiotelegraphy and radiotelephony, when orders were given by flag signals. The flag denotes the ship which must be watched for signals designating orders. Such ...
A rogue wave, by contrast, is a very high wave that could definitely have washed the look-outs away; and the seas off the SE coast of South Africa where the Agulhas current meets western storms are known for rogue waves. If it were a tsunami, the ship would have had to be very near the coast to be impacted and would most likely have been washed ...
Naval flag signalling undoubtedly developed in antiquity in order to coordinate naval action of multiple vessels. In the Peloponnesian War (431 – 401 BCE) squadrons of Athenian galleys were described by Thucydides as engaging in coordinated maneuvers which would have required some kind of communication; [1] there is no record of how such communication was done but flags would have been the ...
This is a list of flags, arranged by design, serving as a navigational aid for identifying a given flag.Uncharged flags are flags that either are solid or contain only rectangles, squares and crosses but no crescents, circles, stars, triangles, maps, flags, coats of arms or other objects or symbols.
An ensign is a maritime flag that is used for the national identification of a ship. [1] It is the largest flag and is generally flown at the stern (rear) of the ship while in port. Depending on the ship's origin, it may sometimes be identical with a jack on the bow of the ship when in a port.
