With no-holds-barred access to the ship and ship’s company, viewers will witness the tasks, triumphs, and tribulations of officers and ratings alike. The average age on board is just 24 and for many - like Helayna from the Wirral and ex drum n bass DJ Ronnie from Essex - this is their first time at sea. Through them and many others we experience the peril of life on the high seas as well as the fun and friendship that can be the reward of close-quarter living in a high-pressure, high-risk environment.
