I saw the first episode of "Making Waves" which was broadcast on BFBS (British Forces Broadcasting Service) 1 and Navy TV. As ex-Navy myself, I found the 1st episode very enjoyable, though with a level of 'soap opera' that is so prevalent amongst such series these days. It is the background details that they get spot on, all the language is accurate and the characters are believable.
Hardly surprising as it was filmed with the full support of the Royal Navy. Most of the extras are RN, and the Type 23 Frigate HMS GRAFTON stood in as the fictional HMS SUFFOLK.
