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 joint 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 not been widely used since World War II; and now almost all curing is done at room temperature. Either used in sheet or alternatively, plate  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 less. 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 together. As the welding can be done very easily with common welding equipment , and 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 surface 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 together. 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 requires special manufacturing techniques, construction tools and construction skills. Aluminium is very expensive in most countries and it is usually not used by amateur builders. While it is easy to cut, aluminium is difficult to weld, and also requires heat treatments such as precipitation strengthening 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 tough, highly resistant to corrosion in seawater, and is because of its copper content a very effective antifouling metal.
Cupronickel may be found on the hulls of premium tugboats , 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 or of the sandwich cored type, in which a core of balsa , foam or similar material is applied after the outer layer of fiberglass is laid to the 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 that less resin and fiberglass cloth can be used in order 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 small 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 to prevent being 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 epoxy , polyester, or vinylester and some kind of fiber cloth fiberglass , kevlar , dynel , carbon fiber , etc.
These methods can give strength-to-weight ratios approaching 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.
