Boat Design, Construction, and Propulsion Traditional fishing vessels have evolved to complement the sea conditions and fishing methods unique to each particular region.

Like fishing gear, boats have passed the test of time. Nevertheless, traditional craft are not without their problems. They often have a very limited range of operation and are not able to go beyond heavily fished nearshore areas. Many will sink if swamped, provid- ing no reserve of safety. Customary building materials are often unavailable. Deforestation in many coastal areas has created a scarcity of quality wood for dugout canoes and larger craft.

Traditional boats can be improved, often without radically altering the basic design; a respect for tradition will increase their acceptance. New vessels should have improved fishing capabilities.

Increased seaworthiness and better fuel performance would permit fishing further offshore for previously unexploited species. Work- ing and storage space wood used for boat construction oil be increased, creating better working conditions and facilitating an increased catch. In areas without harbors, Leachable craft are a priority. Improved designs should also help ensure the safety of the crew by including a second means of propulsion and sufficient buoyancy so that the vessel remains afloat when flooded.

The value of In essence, the boat should require low investment, use minimum fuel, catch as much fish as possible, and have a long service life. This chapter covers some design considerations, examines some new boat construction methods and materials, and describes a few propulsion techniques. DESIGN A fishing boat may be described as a floating platform used to transport the crew, gear, and cargo to wood used for boat construction oil from the fishing grounds and to support the crew and equipment during the fishing operation.

Some of the major factors that affect the design of this plat- form include: Available funds Available materials Skills for building and maintenance Size limitations dictated by water depth or requirement for beaching Distance to fishing grounds Fuel costs Type and quantity of gear used Vessel speed requirements Number of crew, standard of accommodation, cooking fa- cilities Methods of bait and catch preservation Safety features.

Usually when a decision is made to introduce new equipment to an existing fishery, the purpose is to fish for a new species or to fish in a new area.

New boats, new gear, or both may be needed. In some fisheries, it may be necessary to introduce a few larger vessels. Unless a cooperative system already exists, serious problems of equity can arise when a small group gains significant advantage in productivity through access to new large vessels.

The introduction of small, high-speed outboard-motor-powered boats has also brought its share of problems. When the costs of fuel, motor repair, and replacement reach a significant percentage of the. Suman fisherman's income, the attractiveness of speed diminishes figure 1. Small craft design should be based on the traditions of a given region. Vessel sizes and designs that have evolved in an area are usually well adapted to the local fishing gear and methods, the range of operations, construction materials, the winds, and local sea conditions.

A radical departure from the traditional hull design may not gain local acceptance. Rafts are keelless vessels that are common In many areas of Asia. They may be wood used for boat construction oil of bamboo, logs, or plastic cylinders, lashed or fastened. These vessels are beach- landing craft, well suited wood used for boat construction oil heavy surf conditions that would exclude many other boat types.

The kattumaran of South India is a wooden log raft that ranges from 3 to 9 m long. Each log is individually shaped with a definite fore and aft curvature.

Longer logs are placed inboard and shorter ones outboard, and all are lashed. Planking is then nailed over the logs to provide a smooth working surface. Single-hulled vessels are most commonly used in small-scale fisheries. Designs with a high length to beam width ratio and a.

The FAO 8. Multihulled vessels, such as catamarans and trimarans, have traditionally been used as fishing boats in the The Wooden Boat Forum 2020 Pacific Islands. They show promise as fishing boats in other areas, especially where fishermen use one or two outriggers and are accustomed to the idea of multihulIs. Weighing only a ton, it can carry up to 3 tons of fish and gear. Gifford Multihulled boats have a number of positive features for small- scale fisheries.

Their hulls have low displacement to length ratios and high length to beam ratios Ion" and narrow and therefore offer minimum resistance and are easily propelled. Moreover, the stability of multihulIs makes them ideal candidates for sail power.

Small catamarans wood used for boat construction oil lightweight and can be beached and carried with relative ease. Several development projects are attempting to introduce small fishing catamarans wood used for boat construction oil trimarans into areas that tradition- ally have used monohulis.

A number of catamarans have been introduced into the tropics by Gifl. One of them, the Sandskipper 24 figure 1. It has a lateen sail and a diesel engine as propulsion options. This vessel design has proved very satisfactory for gill netting.

It can carry a ton of gear and up to 2 tons of catch in good weather. The construction mate- rials are usually inexpensive and available locally.

However, both materials severely limit the hull shape and are relatively short- lived. Wooden logs are heavy and can result in high fuel consump- tion. While bamboo has the advantage of being lightweight, it is not especially durable. Wood and bamboo will remain important boat building ma- terials in coastal fishing villages where they are readily available.

Where there is a scarcity of good wood, there may be no alter- native to adopting wood used for boat construction oil materials. Newer materials and methods can offer many advantages that compensate for their increased cost. The choice of material urine depend upon a number of factors including cost, availability, longevity, ease of repair, strength, and resistance to corrosion and rot.

Wood Construction Timber Planked hulls have been constructed for hundreds wood used for boat construction oil years throughout the world, and in many areas they are still very popular and highly regarcled. Nevertheless, their importance is clearly diminishing as new construction materials are accepted figure 1. Several variations of planking are commonly used.

In carve! If the planks are very narrow 2. Marine glue or caulking is used to keep the seams watertight. In clinker planking, each plank overlaps the upper edge of the plank below and is attached to it by nails driven from the outside.

This variation is strong and flexible and is ideal for such small craft as dinghies. Wood can be a very satisfactory boatbuilding material: it has good resistance to chafe, gives thermal and acoustic insulation, and allows great variation In hull shape. If good timber is avail- able locally and is economical, it is a logical choice. Suman in many tropical coastal regions, suitable boatbuilding timber is scarce and expensive.

Another disadvantage is the high degree of skill required to build a wooden boat. With only hand tools, construction cam be wood used for boat construction oil time-consuming. The hulls produced are of medium weight and, as they become increasingly waterlogged. Suman with age, consume large amounts of fuel. Many woods are also subject to rot and attack from marine borers. In Tahiti, V-bottom bonitiers are built of imported redwood planking with local timber used for the frames.

Hot dipped, gaI- vanized carve] nails are used for the fastenings. These boats are reported to last well, in spite of being stressed when they are run at high speeds. Plywood Plywood is a sandwich of wood veneers and filler material held together by adhesives.

There are many grades of plywood, but generally, marine plywood made with a waterproof adhesive is required for boatbuilding.

Lower grade plywoods can sometimes be upgraded for marine use if they are coated with a polyester resin. Plywood is very adaptable to small boatbuilding operations. Since sections are cut from large plywood sheets, there are fewer seams than in planked boats. Plywood construction involves building a framework for the hull from planks and then attaching wood used for boat construction oil of marine plywood to this frame.

The plywood hull is held together by nails; marine glue is used to seal the seams. Plywood boatbuilding can be quick, inexpensive, and easy. As long as the surface, and especially the edges, of the plywood are treated with epoxy resin or another sealer, the boat will have a long life.

However, the use of plywood does restrict the hull to hard wood used for boat construction oil shapes, such as flat or V-bottomed boats. Moreover, its resistance to chafe is not high. There are many successful examples of plywood boats built and used throughout the world. Some plywood versions of the Alia, an 8. These vessels have an emergency sail but rely on outboard motors as their principal method of propulsion.

Fishermen generally employ these catamarans for trolling and handlining. In Used Lund Fishing Boats For Sale On Ebay Return Fiji, more than V-bottom fishing boats 8. They are equipped with inboard diesel motors wood used for boat construction oil are also used primarily for handlining and trolling. A plywood single outrigger canoe was designed by FAO in specifically for the waters of Papua New Guinea figure 1.

Surveying a wood boat The problem areas to look out for when surveying an old wooden boat. This procedure would not be very economical, of course. Or to use a preparation with a higher oil content. What would be best? Remains to be investigated. In case the surface treatment cannot keep the wood dry enough for rot not to grow, wood can be saturated with fungisides. Than let it dry properly before following treatments.

Since anti-rot is mainly thinner, no furher poison nor oil can be absorbed by wood cells before the thinner has evaporated. It is also possible to poison wood by ethylene glycol anti freeze or boron, which are water soluble.

Unlike the thinner soluble Used Fishing Boats For Sale Deland Fl Vi anti-rot substances they go to where wood is wet. That is, to where fungi live. It is possible to kill existing fungi in wet wood with these water soluble poisons.

Impossible with a thinner based poison. The water solubility is also a problem, of course :- These poisons get quickly washed away by water. UV-radiation breaks down wood lignin. Remeber, the glue between wood fibers. When lignin breaks down, cellulose fibers turn loose on the wood surface. Wood is shattered little by little.

Opaque paints are best protection against UV-radiation. Most varnishes have some added UV-protection. UV-protection in varnish is finely ground pigment. Little enough to let wood show through the varnish. But enough to prevent at least some UV-radiation from reaching the wood surface. UV-radiation also breaks down the surface treatment. Epoxy as such would be enough to protect wood, but epoxy itself must be protected by paint or varnish.

Paint gives a much better protection than varnish. A good paint may last for 15 years. A good varnish may last three. Varnish "bubbles off" the wood, because wood underneath it breaks loose.

This is, of course, largely a matter of taste. But You can't go very much wrong if You leave the boat interior and decks wood colored, outside of the hull wood colored, white, dark blue, dark green or black. When the car ferry Estonia sank, rescue helicopters had difficulty finding the capsized life rafts, because bottoms of the rafts were black.

The bad luck brought by a black boat may have an explanation here. A black boat in trouble on a stormy sea may be hard to find. This, if anything, is bad for the crew, although luck has nothing to do with it. The wood is removed from the chamber and moved to a drip-dry rack. Depending on the weather, it takes two days to two weeks until the wood is dry enough for transport. This is not the only way wood is treated, but one of the more common.

Many different grades of plywood are pressure treated, including marine-grade. The most popular, which you will find at home improvement stores, is exterior-grade plywood treated for ground contact. There are many rating levels of ground contact.

Regardless of the grade of pressure-treated plywood, there are a few key things you need to know when using it for boat building or repair. Plywood pressure treatment uses water or oil-based carriers that leave behind high moisture content. When looking through a stack of plywood trying to find a nice sheet, the top few are warped like a potato chip. Further down the stack you find a nice, flat piece.

There is a high chance your nice piece of wood will warp like a potato chip too while drying out. With different chemicals and different amounts of moisture left behind by the treatment process, the only way to know for sure is to do a home adhesion test. An example of a home adhesion testing setup. The home adhesion test, is pretty basic. If wood fiber is stuck to the epoxy you have a structural bond, which is what you want.

If the epoxy comes off clean, your bond failed. Pressure-treated plywood and lumber do a good job for their intended purpose. But for boat repair and building, I would shy away from them. Encapsulating the wood in epoxy and using it to seal any holes you drill into the wood results in repairs that can outlast the original plywood by far. An example of a successful bond. The bonding of the epoxy to the plywood was stronger than the bond of the wood fibers to one another.

This timber bonded unsuccessfully.
