Welcome to boyart Country!

Definition: boyart - a boy entered into the Royal Navy as an artificer apprentice Welcome to the official web site of OCAAA - The Old Caledonia Artificer Apprentices’ Association. Within these pages you will find information relevant to our Association and also HMS Caledonia - Rosyth’s College of Knowledge on the Hill - where the majority of our members dedicated their youth to the pursuit of engineering knowledge, alongside other more leisurely pastimes (as some of the pages reveal). We hope that you enjoy your OCAAA browsing experience, but should you be unable to find that which you seek, or experience technical problems with the site, please do not hesitate to drop Spyda an email. You’ll find an email link to him at the bottom of each page Please note that “The Tiff’s Mess” is restricted to OCAAA members only - so if you want the key to that particular door you must join the association!


HMS Caledonia, high on the hill overlooking Rosyth Dockyard, in Fife Scotland. No longer a commissioned establishment of the Royal Navy, it is today in the custody of the Defence Infrastructure Organisation and known as MOD Caledonia. The establishment has changed since we learned our trades, much of our school having been demolished over the years to make it safer and also more suited to today’s requirements. We left our mark here and our alma mater left its mark on us boys no matter what other features time may change. The old adage stands. You can take the tiff out of Cale, but you can’t take the Cale out of the tiff!
