Galleons were large, multi-decked sailing ships developed in Spain and first used as armed cargo carriers by Europeans from the 16th to 18th centuries during the age of sail and were the principal vessels drafted for use as warships until the Anglo-Dutch Wars of the mid-1600s. Galleons generally carried three or more masts with a lateen fore-and-aft rig on the rear masts, were carvel built with a prominent squared off raised stern, and used square-rigged sail plans on their fore-mast and main-masts.
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.
A mortiseand tenon joint connects two pieces of wood or other material. Woodworkers around the world have used it for thousands of years to join pieces of wood, mainly when the adjoining pieces connect at right angles.
The caravel is a small maneuverable sailing ship used in the 15th century by the Portuguese to explore along the West African coast and into the Atlantic Ocean. The lateen sails gave it speed and the capacity for sailing windward (beating). Caravels were used by the Portuguese and Castilians for the oceanic exploration voyages during the 15th and 16th centuries, during the Age of Discovery.
A cog was a type of ship that was used during the Middle Ages, mostly for trade and transport but also in war. It first appeared in the 10th century, and was widely used from around the 12th century on. Cogs were clinker-built, generally of oak. Cogs were fitted with a single mast and a single square sail. They were used primarily for trade in north-west medieval Europe, especially by the Hanseatic League. Typical seagoing cogs were from 15 to 25 meters long, 5 to 8 meters wide, and were of 30–200 tons burthen. Cogs were rarely as large as 300 tons although a few were considerably larger, over 1,000 tons.
Boat building is the design and construction of boats and their systems. This includes at a minimum a hull, with propulsion, mechanical, navigation, safety and other systems as a craft requires.
Strip-built, or "strip-plank epoxy", is a method of boat building. Also known as cold molding, the strip-built method is commonly used for canoes and kayaks, but also suitable for larger boats. The process involves securing narrow, flexible strips of wood edge-to-edge around temporary formers. The temporary formers are usually created via a process called "lofting" whereby a set of tables is used to generate the shapes of the formers. The strips are glued edge-to-edge with epoxy. It is effectively a modern form of carvel which needs no caulking and which is both stiffer and more watertight. In a small boat, there will be just one layer of strip-planking, but larger vessels may have two or three layers which,, forms a light, strong, and torsionally stiff monococque.
A lateen or latin-rig is a triangular sail set on a long yard mounted at an angle on the mast, and running in a fore-and-aft direction. The settee can be considered to be an associated type of the same overall category of sail.
A carrack 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. Evolved from the single-masted cog, the carrack was first used for European trade from the Mediterranean to the Baltic and quickly found use with the newly found wealth of the trade between Europe and Africa and then the trans-Atlantic trade with the Americas. In their most advanced forms, they were used by the Portuguese for trade between Europe and Asia starting in the late 15th century, before eventually being superseded in the 17th century by the galleon, introduced in the 16th century.
Clinker-built 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.
On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost to the sternpost or transom. The garboard strakes are the two immediately adjacent to the keel on each side.
Medieval ships were the vessels used in Europe during the Middle Ages. Like ships from antiquity, they were moved by sails, oar or a combination of the two. There was a large variety, mostly based on much older, conservative designs. Although wider and more frequent communications within Europe meant exposure to a variety of improvements, experimental failures were costly and rarely attempted. Ships in the north were influenced by Viking vessels, while those in the south by classical or Roman vessels. However, there was technological change. The different traditions used different construction methods; clinker in the north, carvel in the south. By the end of the period, carvel construction would come to dominate the building of large ships. The period would also see a shift from the steering oar or side rudder to the stern rudder and the development from single-masted to multi-masted ships. As the area is connected by water, people in the Mediterranean built different kinds of ships to accommodate different sea levels and climates. Within the Mediterranean area during the Medieval times ships were used for a multitude of reasons, like war, trade, and exploration.
The Humber keel was a type of single-masted, square-rigged sailing craft used for inshore and inland cargo transport around Hull and the Humber Estuary, in the United Kingdom, particularly through the late 19th and early 20th centuries.
Ancient boat building methods can be categorized as one of hide, log, sewn, lashed-plank, clinker, shell-first, and frame-first. While the frame-first technique dominates the modern ship construction industry, the ancients relied primarily on the other techniques to build their watercraft. In many cases, these techniques were very labor-intensive and/or inefficient in their use of raw materials. Regardless of differences in ship construction techniques, the vessels of the ancient world, particularly those that plied the waters of the Mediterranean Sea and the islands of Southeast Asia were seaworthy craft, capable of allowing people to engage in large-scale maritime trade.
A hulk was a type of medieval ship used mostly for transports. The hulk appears to have remained a relatively minor type of sailing ship apparently peculiar to the Low Countries of Europe where it was probably used primarily as a river or canal boat, with limited potential for coastal cruising. The only evidence of hulks is from legal documents and iconography, though it is possible that a shipwreck found on the coast of Estonia in early 2022 might be the only known surviving example of a hulk.
The Sparrow-Hawk was a 'small pinnace' similar to the full-rigged pinnace Virginia that sailed for the English Colonies in June 1626. She is the earliest ship to participate in the first decades of English settlement in the New World to have survived to the present day.
Discovered by divers from the French Navy Diving School in 1967, the archaeological investigations of the Roman wreck at Madrague de Giens constituted the first large scale, "truly scientific underwater excavation[s] carried out in France". The wreck lies at around 18 to 20 metres depth off the coast of the small fishing port of La Madrague de Giens on the Giens Peninsula, east of Toulon, on the southern Mediterranean coast of France. Sunk around 75–60 BCE, the vessel has been found to be "a large merchantman of considerable tonnage—400 tons deadweight with a displacement of around 550 tons", making it one of the largest Roman wrecks excavated, with only the wreck at Albenga, Italy exceeding it at the time of its discovery. The vessel wrecked at Madrague de Giens measured around 40 metres in length; has a "wine glass" section which would have given better ability to sail to windward; displayed extended raking of the stem and stern; and had two masts. The hull was characterised by a reverse stempost in the shape of a ram with a big cutwater which "must have given... [the] craft high-performance sailing qualities". The ship sank while transporting a large cargo of wine and black glazed pottery from Italy. It is not known why it sank.
Maritime travel experienced a large leap in the capabilities of seafaring vessels thanks to technological improvements in shipbuilding in the early modern era. Europe, Asia, and the Middle East all saw improvements on prior construction techniques, contributing to the Age of Discovery. As a result, the introduction of these technologies in the production of naval vessels was critical as they allowed nations that utilized these advancements to ascend to a state that could expand its influence at a far greater range. In military engagements, the exploration of new lands and potential colonies, or the transportation of goods for trade, better shipbuilding techniques coincided with prosperity. It is during this time that the practice of naval architecture appeared, as skilled designers could produce designs that had an enormous impact in ship performance and capabilities.
Lashed-lug boats are ancient boat-building techniques of the Austronesian peoples. It is characterized by the use of raised lugs on the inner face of hull planks. These lugs have holes drilled in them so that other hull components such as ribs, thwarts or other structural components can be tied to them with natural fiber ropes. This allows a structure to be put together without any metal fastenings. The planks are further stitched together edge-to-edge by sewing or using dowels ("treenails") unto a dugout keel and the solid carved wood pieces that form the caps for the prow and stern. Characteristically, the shell of the boat is created first, prior to being lashed unto ribs. The seams between planks are also sealed with absorbent tapa bark and fiber that expands when wet or caulked with resin-based preparations.
Phoenician joints is a locked mortise and tenon wood joinery technique used in shipbuilding to fasten watercraft hulls. The locked mortise and tenon technique consists of cutting a mortise, or socket, into the edges of two planks and fastening them together with a rectangular wooden knob. The assembly is then locked in place by driving a dowel through one or more holes drilled through the mortise side wall and tenon.
