Marine information notes (MINs) tend to give information that’s valid for a short period of time, such as timetables for MCA exams relevant to a small group of people, such as training establishments or equipment manufacturers.
MIN have a limited life, the expiry date is shown in the notice.
Marine Guidance Notes give advice on how to comply with MSN or other safety advice.
MGN remain in force until replaced.
MSNs contain the technical detail of regulations called ‘statutory instruments’ (SIs). This is mandatory information, and must be complied with under UK legislation.
MSN remain in force until repealed.
The letter suffix after the M-notice number tells you if it relates to merchant ships and/or fishing vessels:
- (M) for merchant ship
- (F) for fishing vessels
- (M+F) for both merchant ships and fishing vessels
