The Cromarty Firth Port Authority (CFPA) have joined the list of sponsors supporting the IWM Duxford based Catalina as it flies a Circuit of Britain to commemorate the 100th Anniversary of the attempt by Harry Hawker and Harry Kauper in a Sopwith Waterplane.  The CFPA is celebrating its own 40th anniversary with various events.  Of course the Cromarty Firth was a busy base during WW2 but it has been many years since a Catalina last flew over the waters of the Firth let alone put on an air display.
