Concept of Boat d Building Process
The traditional boat building material used for hull and spar
construction. It is buoyant, widely available and easily worked. it is a
popular material for small boats (of e.g. 6-metre (20 ft) length; such
as dinghies and sailboats). Its abrasion resistance varies according to
the hardness and density of the wood and it can deteriorate if fresh
water or marine organisms are allowed to penetrate the wood. Woods such
as Teak, Totara and some cedars have natural chemicals which prevent rot
whereas other woods, such as Pinus radiata, will rot very quickly. The
hull of a wooden boat usually consists of planking fastened to frames
and a keel. Keel and frames are traditionally made of hardwoods such as
oak while planking can be oak but is more often softwood such as pine,
larch or cedar.
Plywood is especially popular for amateur construction but only marine
ply using waterproof glues and even laminates should be used. Cheap
construction 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. No plywood is rot resistant
and should be coated with epoxy resin and/or a good paint system.
Varnish and Linseed oil should not be used on the exterior of a hull for
waterproofing. Varnish has about 60% of the water resistance of a good
paint system. 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
easy 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
200-year-old waka (Maori canoe) caught fire in New Zealand in June 2014
when 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.
More recently introduced tropical woods as mahogany, okoumé, iroko,
Keruing, azobé and merbau. are also used. With tropical species, extra
attention needs to be taken to ensure that the wood is indeed
FSC-certified. (Mario, 2001) Teak or iroko is usually used to create the
deck and any superstructure. Glue, screws, rivets and/or nails are used
to join the wooden components. Before teak is glued the natural oil
must be wiped off with a chemical cleaner, otherwise the joint will
fail.
