1 Page 1 of 5 Title Demonstrate knowledge of traditional wooden boatbuilding Level 3 Credits 10 Purpose People credited with this unit standard are able to: describe the design evolution and development of New Zealand boats; identify materials, tools and processes used in traditional wooden boatbuilding; describe framing types and components, planking types and methods, and fastenings; identify sealing and waterproofing products and methods; describe maintenance for traditional boats, and typical repairs in traditional wooden boatbuilding. Classification Boating Industries > Boatbuilding Available grade Achieved Guidance information 1 This unit standard applies to: a small timber craft that were built in approximately the last 150 years and covers commercial and pleasure types up to approx 20m (65 ). b vessel types that were typically used in New Zealand prior to the widespread use of adhesives and resin impregnated reinforcements. c vessels that are build primarily from wood but may have metal framing. 2 This unit standard can be assessed against off job. 3 Definition Work practice refers to good trade practice involving recognised techniques and processes. Outcomes and performance criteria Outcome 1 Describe the design evolution and development of New Zealand boats. 1.1 Construction evolution of NZ boats is described in terms of materials, tools and techniques.

2 Page 2 of Commercial vessel type evolution in NZ is described in terms of commercial demand. includes but not limited to commercial requirements, fishing, trading scows, freight; maritime operating conditions; availability of materials; designer/builder preference. 1.3 Pleasure vessel type evolution is described in terms of commercial demand. includes but not limited to racing, cruising; maritime operating conditions; weight and performance; availability of materials; designer/builder preference. Outcome 2 Identify materials, tools and processes used in traditional wooden boatbuilding. 2.1 Typical construction materials are identified in terms of timber types, metals for fastenings, caulking, preservatives and paints. 2.2 Typical tools and machinery used are identified according to their use on traditional vessels. cutting tools chisel, plane, spokeshave, adze, draw knife, saws; boring tools drill, brace and bit, awl; caulking tools caulking irons, caulking mallet; driving tools hammers, mallets; marking tools pencil, marking knife, rule, tape; levelling tools level, plumb bob; machinery band saw, circular saw. 2.3 Traditional wooden boatbuilding processes are identified in terms of the construction process. lofting, setting up, framing, planking, steam bending, riveting, caulking, laminating (layers), sawing. Outcome 3 Describe framing types and components. 3.1 Traditional vessels typical hull frame is described in terms of components and purposes. backbone, stem, horn timber, sawn frames, bent frames, ribs, ribbands, floors, bulkheads, keel, keelson, sister keelson, stringers, apron, knees, girders.

3 Page 3 of Traditional vessels typical deck frame is described in terms of components and purposes. deck beams, carlins, coamings, king plank, deck stringers, tie rods, gunwale, clamp, lodging knees, partners. 3.3 Hull framing variations are compared in relation to typical traditional construction. right way up using ribbands, fore and aft planked carvel framing, laminated frame and stringer construction, closely spaced frames. 3.4 Scantlings are explained in terms of moulding, siding and scantling list. Outcome 4 Describe planking types and methods. 4.1 Planking types are described in terms of relationship with the framing types identified in element 3. carvel, clinker, ashcroft, double diagonal, strip planked, other combinations. 4.2 Planking is described in terms of shaping and fitting techniques. includes but not limited to spiling, steaming, order of plank fitting, fitting of garboards and steelers, making and fitting of lands and seams. 4.3 Fastening techniques are described in terms of riveting, nailing, screwing and bolting. includes but not limited to bolt making, riveting, bedding fastenings. 4.4 Waterproofing and sealing methods are described in reference to planking. includes but not limited to caulking and putty, tight seam construction, seam battens, seam detail, glue. Outcome 5 Describe fastenings. 5.1 Fastening types are described according to application suitability. screws, copper nails, annular nails, bolts, coach screws, roves.

4 Page 4 of Methods used to measure and identify fastenings are described in accordance with work 5.3 Fastening materials are described in terms of advantages and disadvantages. includes but not limited to stainless steels (304, 316), brass, bronzes (including silicone bronze), steel, iron, galvanised steel, monel. Outcome 6 Identify sealing and waterproofing products and methods. 6.1 Caulking materials are described in terms of selection and preparation. cotton, oakum, twisting. 6.2 Bedding substances are described according to their applications. includes but not limited to white lead, red lead. 6.3 Sheathing types are described in terms of advantages, disadvantages and differing applications. copper sheathing, timber sheathing, glass reinforced plastic (GRP) sheathing, canvas, paint. Outcome 7 Describe maintenance for traditional boats. 7.1 Ventilation methods and types are described in accordance with traditional work dorade, hatch, mushroom, airflow through structure. 7.2 Annual maintenance items are identified in accordance with work traditional includes but not limited to typical repaint frequency, zinc replacement. 7.3 Suitable haul out and support methods are identified in accordance with traditional work slipways, travel lifts, grids, cradles, shores and wedges.

5 Page 5 of 5 Outcome 8 Describe typical repairs in traditional wooden boatbuilding. 8.1 A typical plank repair due to damage is described in accordance with work 8.2 The effects of stretched fastenings and refastening options are described in terms of vessels movement and watertightness. 8.3 Likely causes and repair of broken frames are described in accordance with work 8.4 A caulking repair is described in accordance with work 8.5 Typical areas of rot and their repair methods are identified in accordance with traditional work Replacement information This unit standard was replaced by unit standard This unit standard is expiring.
