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).
A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds.
In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. In commercial vessels, the latter criterion measured relative to the ship's load line, regardless of deck arrangements, is the mandated and regulated meaning.
Clinker -built (also known as lapstrake) [1] [2] is a method of boat building in which the edges of hull planks overlap each other. Where necessary in larger craft, shorter planks can be joined end to end, creating a longer strake or hull plank. The technique originated in Scandinavia, and was successfully used by the Anglo-Saxons, Frisians ...
Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity, centers of buoyancy, the metacenters of vessels, and on how these interact.

c. 1558 painting of a large carrack attributed to Pieter Bruegel the Elder. A carrack ( Portuguese: nau; Spanish: nao; Catalan: carraca; Croatian: karaka) is a three- or four- masted ocean-going sailing ship that was developed in the 14th to 15th centuries in Europe, most notably in Portugal and Spain.
Middle Eastern designs. Largely due to the absence of a large, oceanic body of water situated by the Middle East, most shipbuilding designs reflected that of shallow water vessels or iterations meant to prepare the ship for deep-sea voyage. The dhow was a long-hulled boat that was utilized for trading extensively in the Islamic world.
Use of computer-aided design has superseded paper-based methods of ship design that relied on manual calculations and lines drawing.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 Ancient Galilee Boat, also known as the Jesus Boat, is an ancient fishing boat from the 1st century AD, discovered in 1986 on the north-west shore of the Sea of Galilee in Israel. The remains of the boat, 27 feet (8.2 meters) long, 7.5 feet (2.3 meters) wide and with a maximum preserved height of 4.3 feet (1.3 meters), first appeared during ...
