Wooden Ship Model
Wooden ship models or wooden model ships are scale representations of ships, constructed mainly of wood. This type of model has been built for over two thousand years. Basic types of wooden ship model construction There are five basic types of construction used in building a wooden ship model hull: *Solid wood hull sawn and carved from a single block of wood. *Gluing together two thinner blocks of wood so that a block is formed with the seam vertical, so that the seam will show running down that surface of the block which is to be the deck. No advantage is gained by having the seam show along the sides of the hull. *Bread and Butter Cutting four or five thinner slabs of wood (the ''Bread'') to be glued (the ''Butter'') later into a laminated block. In this case, the slabs will be oriented so that they sit one on top of the other. *Plank on bulkhead, a technique in which a series of shaped bulkheads are placed along the keel to form a shaped stage which will be covered with plan ...

Shipwright
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC.

Ships
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

Model Boats
Ship models or model ships are scale models of ships. They can range in size from 1/6000 scale wargaming miniatures to large vessels capable of holding people. Ship modeling is a craft as old as shipbuilding itself, stretching back to ancient times when water transport was first developed. History Ancient Mediterranean Ancient ship and boat models have been discovered throughout the Mediterranean, especially from ancient Greece, Egypt, and Phoenicia. These models provide archaeologists with valuable information regarding seafaring technology and the sociological and economic importance of seafaring. In spite of how helpful ancient boat and ship models are to archaeologists, they are not always easily or correctly interpreted due to artists’ mistakes, ambiguity in the model design, and wear and tear over the centuries. Ships "were among the most technologically complex mechanisms of the ancient world." Ships made far-flung travel and trade more comfortable and economic ...

Half Hull Model Ship
A half hull model ship (also known as a "half hull" or "half ship") is a wooden model ship featuring only one half of a boat's hull (watercraft), hull without rigging or other fixtures. Background Prior to the twentieth century, half hull model ships were constructed by shipwrights as a means of planning a ship's design and Sheer_(ship), sheer and ensuring that the ship would be symmetrical. The half hulls were mounted on a board and were exact Scale model, scale replicas of the actual ship's hull. With the advent of computer design, half hulls are now built as decorative nautical art and constructed after a ship is completed."Half-Hull Modeling," (The Apprenticeshop, Bath, ME USA:1980) See also * Wooden model ship * Marine Art References External linksHalf Hull Boat Modelling:An Old Art Turned Full Circle Model boats Ships, Model Marine art Ship design {{Design-stub ...

Metric System
The metric system is a system of measurement that succeeded the Decimal, decimalised system based on the metre that had been introduced in French Revolution, France in the 1790s. The historical development of these systems culminated in the definition of the International System of Units (SI) in the mid-20th century, under the oversight of an international standards body. Adopting the metric system is known as ''metrication''. The historical evolution of metric systems has resulted in the recognition of several principles. Each of the fundamental dimensions of nature is expressed by a single base unit (measurement), base unit of measure. The definition of base units has increasingly been realisation (metrology), realised from natural principles, rather than by copies of physical artefacts. For quantities derived from the fundamental base units of the system, units SI derived unit, derived from the base units are used—e.g., the square metre is the derived unit for area, a qu ...

Scale (spatial)
Spatial scale is a specific application of the term Scale (other), scale for describing or categorizing (e.g. into orders of magnitude) the size of a space (hence ''spatial''), or the extent of it at which a phenomenon or process occurs. For instance, in physics an object or phenomenon can be called microscopic if too small to be visible. In climatology, a micro-climate is a climate which might occur in a mountain, valley or near a lake shore. In statistics, a megatrend is a political, social, economical, environmental or technological Trend (statistics), trend which involves the whole planet or is supposed to last a very large amount of time. The concept is also used in geography, astronomy, and meteorology. These divisions are somewhat arbitrary; where, on this table, ''mega-'' is assigned global scope, it may only apply continentally or even regionally in other contexts. The interpretations of ''meso-'' and ''macro-'' must then be adjusted accordingly. See als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
