Special notes
1
Competence must be demonstrated against a documented scantling determination
system which can be either:
– a rule/schedule method such as the methods contained in The Elements of Boat
Strength, or a documented in-house system.
– an engineering method such as ISO 12215-5:2008 Small craft – Hull construction
and scantlings - Part 5: Design pressures for monohulls, design stresses,
scantlings determination.
2
Competence may be demonstrated for either a traditional plank on frame type vessel
or for a laminated glued timber construction.
3
Competence must be demonstrated on a wooden vessel over 6m in length.

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.
Industry Training Organisations must be accredited by NZQA before they can register
credits from assessment against unit standards.
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.
