Boat building is the design and construction of boats and traditional boat building ireland key systems. This includes at a minimum a hullubilding propulsion, mechanical, navigation, safety and other systems as a craft requires. Wood is the traditional boat building material used for hull and spar construction. It is buoyant, widely available and buildung worked.

It is a popular material for small boats of e. Traditional boat building ireland key abrasion resistance varies according to the hardness and density of the wood and it can deteriorate if fresh water boxt marine organisms are allowed to penetrate the wood. Woods such as Teak mey, Totara irelanx some cedars have natural chemicals which prevent rot whereas other woods, such as Pinus radiatawill rot very quickly.

The hull of a wooden boat usually consists of planking fastened to frames and a keel. Keel and frames are buildin made of hardwoods such as oak while planking can be oak but is more often softwood such as pinelarch or cedar. Plywood is especially popular for amateur construction but only marine ply using waterproof traditional boat building ireland key and even laminates should be used.

Cheap traditiobal plywood often has voids in the interior layers and is not suitable to boat building as the voids trap moisture and accelerate rot as well as physically weaken the plywood. Varnish and Traditional boat building ireland key oil should not be used on the exterior of a hull for waterproofing. Only boiled linseed oil should be used on a boat and only in the interior as it has very little water resistance but it is very buildung to apply and has a pleasant smell.

Note that used linseed rags should not be left in a pile as they can catch fire. A valuable year-old waka Maori canoe caught fire in New Zealand in June traditional boat building ireland key restorers left rags piled overnight. Raw linseed oil is not suited to boats as it stays damp and oily for a long time. Mildew will grow well on raw linseed oil treated timber but not on boiled linseed oil. With tropical species, extra attention needs to be taken to ensure that the wood is indeed FSC -certified.

Before teak is glued the natural oil must be wiped off with a chemical cleaner, otherwise the traditional boat building ireland key will fail. Cold-moulded refers to a type of building one-off hulls using thin strips of wood applied to a series of forms at degree angles to the centerline. This method is often called double-diagonal because a minimum of two layers is recommended, each occurring at opposing degree angles.

The "hot-moulded" method of building boats, which used ovens to heat and cure the resin, has ireeland been widely used since World War II; and now almost all curing is done at room temperature. Either used in sheet or alternatively, plate [18] for all-metal hulls or for isolated structural members. It is strong, but heavy despite the fact that the thickness of the hull can be. The material rusts unless protected from water this is usually done by means of a covering of paint.

Modern steel components are welded or bolted. As the welding can be done very easily with common welding equipmentand as the material is very cheap, it is a popular material with amateur builders. Also, amateur builders which are not yet well established in building steel ships may opt for DIY construction kits.

If steel is used, a zinc layer is often applied to coat the entire hull. It is applied after sandblasting which is required to have a cleaned buikding and before painting. The painting is usually done with lead paint Pb 3 O 4. Optionally, the covering with the zinc layer may be left out, but it is generally not recommended.

Zinc anodes also need to be placed on the ship's hull. Until the mids, steel sheets were riveted. Aluminum and aluminum alloys are used both in sheet form for all-metal hulls or for isolated structural members.

Many sailing spars are frequently made of aluminium after The material kwy special manufacturing traditional boat building ireland key, construction tools and construction skills. Aluminium is very expensive in most countries keh it is traditional boat building ireland key not used by amateur builders. While it is easy to cut, aluminium is difficult to weld, and also requires heat treatments such as precipitation traditional boat building ireland key for most applications.

Galvanic corrosion below the waterline is a serious concern, particularly in marinas where there are other conflicting metals.

Aluminium is most commonly found in yachts and power boats that are not kept permanently in the water. Aluminium yachts are particularly popular in France. A relatively expensive metal used only very occasionally in boatbuilding is cupronickel. Arguably the ideal metal for boat hulls, cupronickel is reasonably traditipnal, highly resistant to corrosion in seawater, and is because of its copper content a very effective antifouling metal.

Cupronickel may traditional boat building ireland key found on the hulls of premium tugboats travitional, fishing boats and other working boats ; and may even be used for propellers and propeller shafts. Fiberglass glass-reinforced plastic or GRP is typically used for production boats because of its ability to reuse a female mould as the foundation for the shape of the boat.

The resulting structure is strong in tension but often needs to be either laid up with many heavy layers of resin-saturated fiberglass or reinforced with wood or foam in order to provide stiffness.

GRP hulls are largely free of corrosion though not normally fireproof. These can be solid fiberglass traditional boat building ireland key of the sandwich cored type, in which a core of balsafoam or traditional boat building ireland key material is applied after the outer layer of fiberglass is laid to buildimg mould, but before the inner skin is laid.

This is similar to the next type, composite, but is not usually classified as composite, since the core material in this case does not provide much additional strength. It does, however, increase stiffness, which means traditipnal less resin and fiberglass cloth buioding be used in biilding to save weight. Most fibreglass boats are currently made in an open mould, with fibreglass and resin applied by hand hand-lay-up method.

Some are now constructed by vacuum infusion where the fibres are laid out and resin is pulled into the mould by atmospheric pressure. This can produce stronger parts with more glass and less resin, but takes special materials and more technical knowledge.

Older fibreglass boats before were often not constructed in controlled temperature buildings leading to the widespread problem of fibreglass pox, where seawater seeped through rraditional holes and caused delamination. The name comes from the multiude of surface pits in the outer gelcoat layer which resembles smallpox. Sometimes the problem was caused by atmospheric moisture being trapped in the layup during construction in humid weather.

Fast cargo vessels once were copper-bottomed hraditional prevent boqt slowed by marine fouling. GRP and ferrocement hulls are classic composite hulls, the term "composite" applies also to plastics reinforced with fibers other than glass. When a hull is being created in a female mould, the composite materials are applied to the mould in the form of a thermosetting plastic usually epoxypolyester, or vinylester and some kind of fiber cloth fiberglasskevlardynelcarbon fiber.

These methods can give strength-to-weight ratios traditional boat building ireland key that of aluminum, while requiring less specialized tools and construction skills.

First developed in the midth century in both France and Holland, ferrocement was also used for the D-Day Mulberry harbours.

After a buzz of excitement among homebuilders in the s, bkilding building has since ureland. Ferrocement is a relatively cheap method to produce a traditional boat building ireland key, although unsuitable for commercial mass production. A steel and iron "armature" is built to the exact shape of traditional boat building ireland key hull, ultimately being covered in galvanised chicken netting.

Then, on a single day, the cement is applied by a team of plasterers. The cement:sand ratio is a very rich ; do not call traditional boat building ireland key concrete!

As the hull thickness is typically 2. Properly plastered ferrocement boats have smooth hulls with fine irrland, and amateur builders are advised to use professional plasterers to produce a smooth finish. In the s and s, particularly in Australia and New Zealand, the cheapness of ferro construction encouraged blat builders to build hulls larger than they could tradiitional, not anticipating that the fitting-out costs of a larger boat can be crippling.

For example, a sea-going vessel needs a hull which is more stable and robust than a hull used in rivers and canals. Hull types include:. Boat construction underway at Bheemunipatnam [19].

The purpose of this website is to raise awareness of the rich diversity of our maritime traditions. Background The cooperative originated as a group of enthusiastic and committed volunteers whose founding aim was to raise awareness and interest in Ireland's diversity of coastal and inland water craft.

The need for a comprehensive survey of Ireland's traditional water craft has been recognised for some time. It is a need which becomes more pressing as our stock of indigenous boats diminishes.

But tradition is persistent, and Ireland still possesses a remarkable diversity of boat types on its coasts, in lakes and on rivers, even if their numbers are in decline. Much work remains Traditional Boat Building Skills Reading to be done in relation to Ireland's traditional boats. A great many boats of heritage value have yet to be recorded, particularly those of the inland waterways whose stock of indigenous craft has proven more vulnerable to change than those of coastal districts.

The Revival The growing interest in 'classic' boats has helped sustain traditional skills and knowledge. Without this skills base, the ability to restore, replicate and handle the boats is endangered. It is therefore vital that we act now to preserve and record this irreplaceable part of our cultural heritage. This site is intended to provide a platform to continue the work of the many contributors to the book Traditional Boats of Ireland, and to invite others to participate in this important work.

It is hoped the resources and information presented here will encourage people to share their knowledge and interest in the subject of traditional boats. Another explanation is that it comes from the Latin navis , and it has also been suggested that it derives from the Irish nae , a boat.

It is suggested that the prototype of this wooden boat was built on Inishnee around and based upon a tender from a foreign vessel seen in Cleggan harbour. These wooden boats progressively supplanted the canvas currach as a workboat around the Connemara coast. The currach has traditionally been both a sea boat and a vessel for inland waters. The River currach was especially well known for its shallow draft and manoeuvrability.

Its framework was constructed of hazel rods and sally twigs, covered by a single ox-hide, which not only insulated the currach, but also helped dictate its shape.

These currachs were common on the rivers of South Wales, and in Ireland were often referred to as Boyne currachs. However, when Ireland declared the netting of salmon and other freshwater fish illegal in , it quickly fell out of use. During the Neolithic period, Traditional Boat Building Techniques 4ml [3] the first settlers landed in the northern part of Ireland, likely arriving in boats that were the ancestors of the currach. Development in joining methods of wood during the Neolithic period made it possible to eventually create what the currach is today.

Hide-covered basket origins are evident in currachs found in the east of Ireland, and using the skins for lining currachs in the Neolithic period likely was how the early Irish were able to make their way over to the British Isles.

The currach represents one of two traditions of boat and shipbuilding in Ireland: the skin-covered vessel and the wooden vessel. The flimsy construction of the former makes it unlikely that any remains would be available for the marine archaeologist, but its antiquity is clear from written sources. One of these is the Latin account of the voyage of St Brendan who was born c.

Tar was used to seal the places where the skins joined. A mast was then erected in the middle of the vessel and a sail supplied. An Irish martyrology of the same period says of the Isle of Aran that the boat commonly used there was made of wickerwork and covered with cowhide. Gerald of Wales , in his Topographia Hibernica , relates that he was told by certain seamen that, having taken refuge from a storm off the coast of Connacht , they saw two men, long-haired and scantily clad, approaching in a slender wickerwork boat covered in skins.

The crew found that the two spoke Irish and took them on board, whereupon they expressed amazement, never before having seen a large wooden ship. The consistency in accounts from the early Middle Ages to the early modern period makes it likely that the construction and design of the currach underwent no fundamental change in the interval.

A 17th-century account in Latin by Philip O'Sullivan Beare of the Elizabethan wars in Ireland includes a description of two currachs built in haste to cross the River Shannon. The larger was constructed as follows: two rows of osiers were thrust in the ground opposite each other, the upper ends being bent in to each other ad medium invicem reflexa and tied with cords, whereupon the frame so made was turned upside down.

Planks, seats and thwarts were then fitted inside cui e solida tabula, statumina, transtraque interius adduntur , horse hide was fixed to the exterior and oars with rowlocks were supplied. This vessel is described as being able to carry 30 armed men at a time. The currach bears a close resemblance to the coracle, a similar circular rowboat used in Wales, and to the wide family of circular boats termed "coracles" common throughout South and Southeast Asia.

These non-Irish coracles all ultimately trace their origin to the quffa , a round Iraqi riverboat dating to the 9th century BCE , or possibly even as early as the 2nd millennium BCE. British ethnologist James Hornell , who studied the currach, coracle, and quffa extensively during the early 20th century, believes that the currach was developed independently of the coracle and quffa in a case of multiple invention. The construction and sailing of a seagoing curach of the 17th century � a hybrid of the skin-covered and plank-built boat � was depicted in some detail by an Englishman, Captain Thomas Phillips: "A portable vessel of wicker ordinarily used by the Wild Irish".

Though doubt has been cast on the accuracy of these sketches, [12] they are detailed and represent a valid development of the ocean-going currach. The vessel is some twenty feet long: it possesses a keel and a rudder , with a ribbed hull and a mast amidship.

Because of the keel, the craft is shown as being constructed from the bottom up. A covering presumably of animal hides was added, the sides being supported by rods in the interval. The mast is supported by stays and by double shrouds on each side, the latter descending to an external shelf functioning as a chainwale.

The forestay is shown as passing over a small fork above the yardarm , which supports a square sail : a branch is tied to the mast-top. The stern is surmounted by double half-hoops which could support a covering. The sketches by Phillips imply that such a vessel was common in his day. The keel would improve the handling of the boat [13] but the hull would remain flexible.

Currachs in general adhere to a plan designed to produce a sturdy, light and versatile vessel. The framework consists of latticework formed of rib-frames "hoops" and stringers longitudinal slats , surmounted by a gunwale. There are stem and stern posts, but no keel. Thwarts are fitted, with knees supplied as required. Cleats or thole pins are fitted for the oars, and there may be a mast and sail, though with a minimum of rigging.

The outside of the hull is covered by tarred canvas or calico, a substitute for animal hide. Currachs were used in the modern period for fishing, for ferrying and for the transport of goods and livestock, including sheep and cattle.

Use of the currach was not continuous or universal along the Atlantic coast. In the modern period it did not reach Kerry in the southwest of Ireland until the late 19th century c. Until then the only vessel used was the heavy wooden seine boat , which required eight men to row it.

Currachs produced here follow the same general construction process as many other Currach styles but in Boyne they implement the use of tarred canvas as the outer layer. Detailed plans are available for Donegal currachs. The Donegal Sea Currach is very similar to the Boyne Currach in construction and style although the two are produced on opposite coasts from each other.

The Donegal Sea Currach is the last traditional Irish craft to use the free paddle instead of the traditional oar. South Mayo currachs differ from most other currach types in that, instead of the stringers which elsewhere run outside the latticework frame, the bottom and sides are covered with a thin planking.

In Achill Island the currach is built with double gunwales. The Connemara currach is also distinguished by a double gunwale and by a particular form of pivoting block or "bull" attached to one side of the squared region of the loom of the oar. The Aran islanders, like the Blasket islanders further south, were assiduous users of the curach. Unusually for the area a sail was used, though without shrouds or stays.

Apart from the halliard, the only ropes were the tack, led to a point near the stem, and the sheet, carried aft and secured to the last thwart. Currach races remain popular. In the mids and early s the Seoighe cousins excelled by winning many county and All Ireland championships, including three in a row of the latter. The Clare currach closely resembled that of the Aran Islands.

In construction, a series of wooden markers were sunk into the ground at definite distances apart. These helped show the width desired for the lower gunwale frame. This was constructed first, followed by the upper frame, and the thwarts were then nailed into place. Currachs covered in cowhide were still common in the s above Traditional Boat Building In Maldives 80 Lough Ree, in the centre of Ireland.
