After more than 5-million people tuned in to watch the debut six episodes this summer, the fly-on-the-wall documentary is set to return to living rooms early next year having been recommissioned for another outing.
Show-maker Middlechild Productions has already started filming again with the Maritime and Coastguard Agency, with camera crews lined up to capture footage well into the winter.
The action they cover is expected to range around the country and across the organisation: from Coastguard Rescue Teams, maritime rescue coordination centres and helicopter crews to marine surveyors and investigations teams.
The first series was over a year in the making and was shown on the primetime 9pm slot on Sundays. It revealed how the MCA works both as rescuer and regulator towards the common goals of safer ships, safer lives and cleaner seas.
