Application
This unit of competency covers the skills and knowledge required to reproduce design lines onto sail cloth using manual techniques, for the purpose of sail making.
The unit of competency applies to a traditional sail making technique that does not require the use of computerised equipment.
The unit of competency applies to the laying out of sail cloth on a floor and reproducing in full scale, the 'line drawings' and 'table of offsets' supplied by the sail designer onto the fabric in order to achieve a pattern with a 3-D outcome.
Work may involve interaction with other people in the workplace, including supervisors and production personnel or sail designers.
Work may be conducted in small to large scale enterprises and may involve individual and team activities. Work is performed within defined procedures under supervision of the sail designer.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

Assessment Conditions
Assessors must:
satisfy the assessor competency requirements that are in place at the time of the assessment, as set by the VET regulator
have vocational competency in applying lofting skills to sail making, at least to the level being assessed, with relevant industry knowledge and experience.
Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation, required including relevant workplace procedures, product and manufacturing specifications associated with this unit.
