Master: Law, Certificates and Surveys in the MCA orals
The Master Unlimited oral (STCW II/2, MIN 653 section 5) tests the master’s legal knowledge at management level. Examiners expect you to know which certificates the ship needs, how surveys are organised, what the law says about crew and records, and how to handle port state control and commercial documents.
- Which oral
- Master Unlimited (STCW II/2) and Chief Mate orals; there is no Part A at this level

- Our drill
- 10 questions from 36 Master: Law and Surveys questions, untimed, a model answer after every one; one free attempt, unlimited with a pass

Study notes
- Statutory certificates include the cargo ship safety construction, equipment and radio certificates (or a passenger ship safety certificate), the International Load Line Certificate, the IOPP Certificate, the Safety Management Certificate, the International Ship Security Certificate, the Maritime Labour Certificate and the International Tonnage Certificate.
- The harmonised system of survey and certification groups surveys as initial, annual, intermediate, periodical and renewal, with most certificates valid for five years with annual endorsement.
- The minimum safe manning document states the number and grades of seafarers the flag state requires; the master must not sail below it.
- The official log book records the events the Merchant Shipping regulations require, such as births and deaths, offences, drills and inspections; entries are signed and the book is kept for the period the law requires.
- Hours of rest (MLC 2006 and STCW): at least 10 hours in any 24-hour period and 77 hours in any 7-day period; rest may be split into no more than two periods, one of at least 6 hours, with no more than 14 hours between them.
- A bill of lading is a receipt for the goods, evidence of the contract of carriage and a document of title. A letter of protest records a disagreement or an event that may lead to a claim; a note of protest is made before a notary or consul after bad weather or an incident.
