Questions

Questions candidates ask about Deck Safety

How many Deck Safety questions are on the exam, and how many can I miss?
50 questions, 15 wrong allowed, 70% to pass — and that one paper covers Deck General as well, so the 50 are shared between the two, not 50 each. Your Approval to Test letter assigns the modules; it is the final authority on what you sit.
Is the Deck Safety paper identical for OUPV and Master under 100 GRT?
The subject is the same and the NMC code differs by route: Q170 / Q356 on the OUPV papers. A Master under 100 GRT candidate is graded within the 210-question series at 70% and the NMC publishes no per-module mark for that route.
Where do the Deck Safety answers come from?
Firefighting, man overboard, distress signalling, PFDs and EPIRBs. Every answer on this site opens with the regulation it tests and links to the text — 33 and 46 CFR, the COLREGs and Inland Rules, or Bowditch. If a citation ever stops resolving, the question leaves rotation.
Are these the real exam questions?
No, and nobody who says otherwise has them: the NMC does not publish its question bank. These are written to the same modules, topics and format, each one checked against the primary text by a separate model before it is published.
