Current coastguards were joined by former coastguards on board a Northlink ferry, with many old friends and colleagues seeing each other for the first time in years.
It was an opportunity to share stories, discuss the changing times and reflect on two centuries of keeping people safe across the north-east of Scotland.
Coastguard Chaplain Tom Ebbens was in attendance, alongside coastal operations area commander Calum Christie.
A formal ceremony - hosted by the Lord Provost - was attended by senior officers at the Maritime Museum in the Granite City, with some special guests presented with their long-service awards.
And, taking inspiration from the event in Orkney last month, there was a very special cake baked by the daughter of Aberdeen Maritime Rescue Coordination Centre Team Leader Gordon.
