The things a captain or chief officer would
otherwise find out from a surveyor.
New and revised MGNs
What the MCA has issued or withdrawn since the last briefing, and which vessels it reaches.
IMO circulars that matter
SOLAS and MSC amendments filtered down to the ones that change something aboard a yacht, not the full firehose.
Flag and code changes
REG Yacht Code amendments and notices from the registries yachts actually fly.
Dates worth diarising
Entry-into-force dates and transition deadlines, far enough ahead to plan a yard period around.
Linked to the source
Every item links to the original notice. The briefing tells you it happened; the source tells you exactly what it says.
Written for crew
By people who build the software that records this, for the people who have to do it. No press releases.
