Special notes
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.

Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated
authority for quality assurance, before they can report credits from assessment against
unit standards or deliver courses of study leading to that assessment.

Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
