(Enacted 1986) Cap 313R Sched 7 SYLLABUS FOR PLEASURE VESSEL ENGINEER GRADE I [rules 4 & 6] There are 2 engine types-diesel or petrol. The relevant examination comprises a written objective test paper or an oral examination and the candidate may elect to be examined on either or both engine types. (L.N. 327 of 1989) Introduction The engineering knowledge to be shown by a candidate is that which is required for the safe use and operation of the main propulsion engine and associated systems together with auxiliary machinery and electrical systems. Candidates are expected to have a good knowledge of the engineering principles involved, general maintenance and the recognition and location of faults. The examination demands a greater depth of knowledge and a higher standard of answer than that required for the Grade II Certificate. Candidates will not be required to have detailed knowledge of maintenance or engineering principles beyond showing an understanding of how to rectify simple faults that might occur when the vessel is under way.
