 The UnMuseum - "Floating Tombstones"
Concrete, a mixture of sand and gravel bonded together with a cement to form a solid, heavy mass similar to stone, seems an unlikely substance to be used in ship construction.
Ship builders took the idea a Norwegian inventor had patented a few years before in 1912 to use concrete instead of steel for the ship's hull.
The concrete ships that were built followed the design of steel ships of that era, but required much thicker hulls to get the same amount of strength that the steel gave.

 Ship - Wikipedia, the free encyclopedia
One can measure ships in terms of overall length, length of the waterline, beam (breadth), depth (distance between the crown of the weather deck and the top of the keelson), draft (distance between the highest waterline and the bottom of the ship) and tonnage.
Before mechanisation, merchant ships always used sail, but as long as naval warfare depended on ships closing to ram or to fight hand-to-hand, galleys dominated in marine conflicts because of their maneuverability and speed.
A few ships have used nuclear reactors, but this is not a separate form of propulsion; the reactor heats steam to drive the turbines.

Concrete, produced at a rate of five billion cubic yards per year, is the second most widely consumed substance on Earth, after water.
Concrete is however, a favored material of many talented architects and engineers who value its versatility, its strength, and its almost unlimited potential as a medium for imaginative forms and surfaces.
According to the American Concrete Association's, Pavement Progress report, Concrete is a heterogeneous system of solid, discrete, gradiently inorganic mineral aggregates, usually plutonic or sedimentary-calcareous in origin, embedded in a matrix compound of synthesized polybasic alkaline and alkaloidal silicates held in an aqueous solution and coprecipitate dispersion with other amphoteric oxides.
