Archimedes' investigation of paraboloids was possibly an idealization of the shapes of ships' hulls. Some of the paraboloids float with the base under water and the summit above water, similar to the way that icebergs float. Of Archimedes' works that survive, the second book of On Floating Bodies is considered his most mature work. [6]
The flying island of Laputa from Gulliver's Travels. (Illustrated 1795.) In science fiction and fantasy, floating cities and islands are a common trope, ranging from cities and islands that float on water to ones that float in the atmosphere of a planet by purported scientific technologies or by magical means.
A 10,000-ton ship's hull must be built wide enough, long enough and deep enough to displace 10,000 tons of water and still have some hull above the water to prevent it from sinking. It needs extra hull to fight waves that would otherwise fill it and, by increasing its mass, cause it to submerge.
Sailors' superstitions are superstitions particular to sailors or mariners, and which traditionally have been common around the world. Some of these beliefs are popular superstitions, while others are better described as traditions, stories, folklore, tropes, myths, or legends.
Swing moorings also known as simple or single-point moorings, are the simplest and most common kind of mooring. A swing mooring consists of a single anchor at the bottom of a waterway with a rode (a rope, cable, or chain) running to a float on the surface.

Often referred in Nordic folklore, the massive, squid-like sea creature is characterized by a penchant for dragging massive ships and the people on them down to its deep, watery, lair.
The 82-foot-tall steel and glass AquaDome crowns part of the top of the ship, housing a theater where high-divers perform, a 55-foot-tall water curtain feature, a bar and Royal Caribbean’s first ...
When designing a pontoon bridge, the civil engineer must take into consideration Archimedes' principle: Each pontoon can support a load equal to the mass of the water that it displaces. This load includes the mass of the bridge and the pontoon itself. If the maximum load of a bridge section is exceeded, one or more pontoons become submerged.
