FllV/IP117(Rev.?) 1. 1N!rR0IYucr1m TRE PURPOSE OF THIS FUBIZCATICIET is to present some basic designs of boats that are simple to oonstruot,for use-in small-scale, non-industrial fisheries. All the designs ehown here are of the flat bottom type; that is: the bottom is flat when seen in the transversedireotion,while lengthwisethere is a slight ourvaturs. In the majority of the presentdesigns, the shape is simplified to the extent that the sides are built up with parallelplanks and the rocker of the bottom is determinedsimply by the curvature and the flare of the side planks, so no building‘jigis necessary.

THE E OF CONSJ!RUCTION of flat bottom boats, because of the simple, straight-lined "fp" frames and the uncomplicated planking, is consideredto be their min~advantages, realizing also '&at this normallymakes them the least expensiveof all planked wooden boats. THE WALLOW DRAUGHT! is an importantfeature for many purposes like navigationon shallowrivers and lakes or in swamp areas or close to the shore. For beach landing operations,it means that the boat can be kept afloat until it actually touches the beach, and because of its flat bottom it rests firmly on the ground after hauling up. GOOD TRANSVERSESTABILITYwhen comparedwith round bilge or V-bottom boats with the same weight and overallbeam is another advantageof flat bottom boats. This means that they give a stable working platform for fishing operations. BIG FLOOR SPACE INSIDE THE BOAT is a valuableasset for oertain fishing operations like gillnetting or pot fishing where a workingposition standingnear the side is normal; this is another easily possible,favourablefeature of the flat bottom boat configuration. THE ADAPMBILITY FOR SERIES PRODUCXON is high, utilib!ngsimple moulds and templates; series productionis possiblewith a small labour foroe. In one country in Africa, the eystem of kit productionin.a central place with good aooess to suitable timber, ard assemblyin the differentfishing villages,has been introduced with great success. EXPERIENCED BOATBUILDFRSare not necessaryfor the construction of flat bottom boats since the ambunt of difficultboatbuildingwork is reduced to a minimum, Knowledgeof general carpentryis required,supplemented with a few weekstraining in this particular type of construction. STABDARDSIZES OF TIRBER can be used throughoutin the majority of the designs presented. The requisitetimbers oan be obtained directlyfrom the timber store or sai mill without timber spiling or other difficultadjustmentsof the edges being required. Since,standard sizes are different in differentoountri'es and strengthand stiffnessarenot the same for all boatbuilding timbers,the specifications given should be taken more as guidelinesthan as striot instructions. THE RAIN DISADVARTAGES of flat bottom boats are their general tendency to slamming in requiringspeed reduction,and the tendencyto sidewaves9 resulting in discomfort,arxl drift in wind and waveal due to lack of a deep keel. These featuresrestrict the area of uee for these boats to protectedwaters, inland waterwaysand some lakes. Spray and water since there are no bilges where this that enter the boat can also be quite uncomfortable, water can be collectedand easily bailed or pumped out. THE BOAT DESIGNS presentedhere are suitablewhere low cost, or ease of construction, are all importantfactors and where a somewhatreduced seaworthiness or seakindliness can be accepted,or where extreme shallow draft requirements arean over-ridiugconsideration.

FIIV/T117(RiV.i\ BUIZSINGPROCEDURES
THE! SIMPLESTVERSIONS of flat bottom boats have croes-laid bottom planke nailed directlyto the sidee, and the lower side planka on each side are increasedin thickness to take the nail6 without eplitting. The frames are mainly neceesary to hold out the beaauee the main transversestrengkhcornea from the aroas-laid sides during construotion, bottom planks. The bottom planks have to be held togetherby longitudinal bottom stiffeners, and the side planks by vertical side stiffeners(intermediate eide frames). A slight bending of the bottom planks when crossingwaves can be toleratedas long as it does not affect watertightness. Except for MLW-6, which is built over a jig, when one or eeveralboate only are to be built the construction procedureis as follows: Seleot timber and fasteningsaccordingto specifications on drawings '. (see Chapters 3 and 4 regardingselection of timber and fasten&e).

Join lower side planks to obtain the required length using butt blocks on the inside. Mark positionof all main frames and intermediate frames.
5. Assemble the lower side planks, frames, stem and transom on the boat ground or on a flat floor. When this is done the shape of ,th+ ie given.
6.
Fasten side stiffenersto lower side planke and complete side planking. Turn the boat over, check the bevel on the lower side planks for a perfect fit with the bottom planks. Start plankingthe bottom from the stern, working toward the stem. Apply a strand of cotton and bitumastic compound in the joint between the sidea and the bottom. If the bottom planking is made of a timber that swells and shrinks considerablyit is necessary to leave a gap, the thickness of a hacksaw blade between the planks. Never fit the bottom planks tight if they are made of pine or similartimber since the bottom planks will buckle as they swell. With most stable tropicalhardwoods, however, the bottom planks can be fitted tight on the inside with a small outgaugefor caulking the outside. Apply wood preservativeon all surfaces. A strand of cotton is driven into the seams with a proper caulking iron and not J screwdriver, chisel or putty knife. The seam ic finally renderedwatertightby fillingthe joint with bitumastiocompound. Painting the outside of the bottom with bitumaeticpaint is the beet and cheapestway. The sides can be painted hut applicationof wood preservationwill give a better and cheaper protectionto the timber against rot.

When sariee productionof 10 or more boats 4s envisaged,building upside down over a procedure jig is the quickest and most economicalmethod. In this caee the construction follows that shown for boat MLW-6. Slight differencesin proceduremay be necessary to inoorporatefixed frames which are indicatedin some designsand these shouldbe prepared and fitted to the jig with the moulds and permanentlyfastenedto the hull before it ie removed from the jig.

SEXJXX?ION OF TIMBER
timber are: THE MAIN QUALITIESsought in a boatbuilding (a) Rot resistance- Rot is the main enemy of wooden boats operating in tropical fresh waterandthe timber should be selectedwith this in mind. The types of timber with high naturalresistanceto rot are normallyknown by the boatbuilders in the area but ForestryDepartmentswill also be able to give precise information regardingdurabilityof various local timbers. High resistanceto rot can also be achievedby pressurelimpregnationof timbers, The local Forestry Departmentcan give advice on which speciesof timber would be suitable. Besides being easily treatedby pressure-impregnation it must be relativelystable, with good strengthqualitiesand not split easily when nailed or screwed. (h) Stability- A timber that is not stable will shrink excessivelywhen it dries out and thereby open up the seams with resultingleaks. On the other hand, if the same timber is dry when the boat is being built the bottom planks will swell excessively after being put into water causingGreat strain on the fasteningsand making the planks buckle with consequentleaks along the chine. The tangentialshrinkageshould preferably be below 4 percent when dried from green to 15 percent humidity. The best hardwoodshave a tangentialshrinkage of only 2 peroent - a boat built of such timber will, therefore,have less problemswith le&kagedue to swellingand shrinkage. (c) Good strenCthqualities- The weight of the timber will give an indication of the strength. The heavier the timber is the strongerit will be. A heavy timber will, therefore,permit a slightreduction in plankingthicknesscompared with a lighter timber. (d) Take nails and screws without splitting- The problem of splittingwhen nailingthe planks can partly be solvedby preboring holes for the nails. Holes for screws must always be prebored.

SELECTION05 FABTENINGS
(4 (b) (4 (4
All nails, screws and bolts shouldbe hot-dippedgalvanized. Copper nails or brass screws are expensiveand their use is not warranted for boats operatingin fresh water. Bolts should be of carriage ty,ps with cupped head and a square nut. A galvanizedwasher should be placed under the nut. , The type of galvanizednails to be uTed is often determinedby winat is available. Round nails or square nails are both acceptablebut'the diameter should not be less than l/7 of the plank thicknessand the length at least 2:'le times the plank thickness. For example, for 20 mm planking nails should have a minimumdi‘ameter of 3 mm and a minimum length of 50 mm. If the timber has a tendency to snlit, a hole slightlysmzller than the nail diameter shouldbe drilled before nailing. If the nail is to be clenched,the nail should be tapped over at the end and, with a dolly against the nailherui, tapped down so that the point enters the iiood and hammered hard down to draw up tight. The point shouldbe clenchedacross the grain, not along the grain since this often leads to splitting.
