There are many terms for parts of a ship with functions similar to a bridge. Depending upon the design and layout of a ship, some of these terms may be interchangeable. Traditionally, sailing ships were commanded from the quarterdeck, aft of the mainmast, where the ship's wheel was located (as it was close to the rudder).
Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
Walker Evans (November 3, 1903 – April 10, 1975) was an American photographer and photojournalist best known for his work for the Resettlement Administration and ...
A carvel boat has a smoother surface which gives the impression that it is more hydrodynamically efficient since the exposed edges of the clinker planking appear to disturb the streamline and cause drag. A clinker certainly has a slightly larger wetted area, but a carvel hull is not necessarily more efficient: for given hull strength, the ...
A flat spring fixed only at one end like a cantilever, while the free-hanging end takes the load. Coil spring Also known as a helical spring. A spring (made by winding a wire around a cylinder) is of two types: Tension or extension springs are designed to become longer under load. Their turns (loops) are normally touching in the unloaded ...
In the marine industry there is a long-standing and important tradition of "jointness" in marine forensic investigations, where all parties at interest examine the same things at the same time. However, due to the criminal character of OWS violations the jointness concept is abandoned, which leads to very poor technical investigative methods ...
The Nydam boat, an early example of clinker construction. The earliest example of ship and boat building using overlapped planking joined with metal fastenings is in an extended logboat from Björke in Sweden. This dates to c. 310 AD. The Nydam boat is an almost complete example of a boat built with clinker construction. It has overlapping ...
The Braine steering gear was a fine-tuned system of quadrant on the rudder stock driven by the tension of the mainsail sheet and damped by a rubber band. A more sophisticated system called the vane gear was later devised, it relied on a small vane or airfoil driving the main rudder via an adjustable system
