Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Ship design calculations are also required for ships being modified (by means of conversion, rebuilding, modernization, or repair).
Lofting is the transfer of a Lines Plan to a Full-Sized Plan. This helps to assure that the boat will be accurate in its layout and pleasing in appearance. There are many methods to loft a set of plans. Generally, boat building books have a detailed description of the lofting process, beyond the scope of this article.
Hence, waterlines are a class of "ships lines" used to denote the shape of a hull in naval architecture lines plans. [1] The load line (also known as Plimsoll line) is the waterline which indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy.

Use of computer-aided design has superseded paper-based methods of ship design that relied on manual calculations and lines drawing. Since the early 1990s, a variety of commercial and freeware software packages specialized for naval architecture have been developed that provide 3D drafting capabilities combined with calculation modules for ...
The plans in these books were used in many cases to illustrate potential ship designs for Navy leadership, usually the General Board, of the implications of certain design characteristics and were used to help make decisions regarding them. Sometimes the plans were prepared after approved characteristics had been published to accommodate ...
The lines and sail plan are in the William H. Webb's Plans Of Wooden Ships. [11] Freight rates to the goldfields had by this time skyrocketed to such an extent that a ship could pay for its construction with a single voyage. Challenge, 1851 clipper. Webb's clipper designs "employed the most judicious use of timber of all the major shipbuilders."
Lines plan for the hull of a basic cargo ship MS Freedom of the Seas under construction in a shipyard in Turku. A ship will pass through several stages during its career. The first is usually an initial contract to build the ship, the details of which can vary widely based on relationships between the shipowners, operators, designers and the ...
The plans for the hull of a 26-ft yawl built for the Royal Navy in 1809 in Portsmouth Dockyard. It is fitted for 10 oars. The yawl as a type of Royal Navy ship's boat appeared early in the second half of the 17th century. In early mentions, they were sometimes referred to as "Norway yawls", so showing a Scandinavian influence.
