Orals Revision: Seaworthiness & Stability (Master 200/OOW 500 Yacht Route)

Orals revision card — Master (code vessels less than 200 GT)/Officer of the Watch (yachts less than 500 GT) Oral Examination Syllabus, Section 2.5 'Seaworthiness of the Ship' (MCA, gov.uk, updated 17 June 2026). Small-vessel/yacht route — a different syllabus from the Unlimited CoC track covered elsewhere in this series. This is a qualitative, recognise-and-respond brief rather than the calculation-heavy stability syllabus tested at Unlimited level.
