Careers: how to become a deck officer

Does working on board a ship and seeing the world sound appealing? Find out from a Deck Officer what it's like and see how Sea Cadets can help

James Charles knew he wanted to work at sea from an early age. At 12, he decided to try out a parade night at his local Sea Cadets unit and hasn’t looked back. “I was impressed by the training on offer,” he says. “I made some very close friends and learned a lot about myself.”

After his A-levels and with career choices to make, James began applying for merchant navy scholarships, and “chose the commercial shipping industry over the Royal Navy based upon the type of ships I wanted to work on.”

Getting started

James’s career at sea began 10 years ago at Warsash Maritime Academy in Southampton. “The past decade has been truly incredible,” he says. “As an Officer Cadet, I was fortunate to sail on a range of vessels, from large cruise liners and RoRo [roll on-roll off] ferries to chemical tankers, gaining invaluable insights into how  they operate.

“My cadetship included crossings of the Atlantic, Pacific and Indian Oceans as well as a going through the world-famous Panama Canal,” James says
of his early career.  “From the Cape of Good Hope off South Africa to the cold climate of Svalbard in the Arctic Circle, this has made for some incredible memories – and interesting stories!”

The day-to-day 

After completing his Navigational Officer training, James is now a Second Officer, working rotations of three weeks on duty, then three weeks off. “This allows for a comfortable family and social life,” he says. “Now, with two children, I prefer weekly periods at sea as opposed to months.”

James’s daily duties on board include being responsible for the safe navigation of the vessel as well as maintaining a record of all activity onboard. He is also responsible for the upkeep of the ship’s equipment, particularly life-saving equipment and fire-fighting appliances.

Life at sea

Even though James has his dream job, there are still downsides – like any career. “Some days can be very long, if there is an inspection of a particular job planned,” he explains. “The fact that you can’t go home at the end of the day can be a challenge, as can managing shoreside commitments when doing long trips.”

But for James, the benefits outweigh the challenges. “I enjoy the variety of roles, and that no two days are the same,” he says. “There are drills, paperwork and maintenance. Shore time is an advantage, too – and being paid to travel the world!” 

James’s next goal is to achieve the Master Mariner certification, then a role in marine pilotage, training and education. He’s also returned to his Sea Cadets roots as an instructor. “Sea Cadets gave me the confidence and ability to turn my dreams into a reality. I am ever grateful to the instructors that helped me, so I wanted to provide these opportunities myself.”

James urges anyone thinking about a career at sea to explore their options: “It offers so many great experiences and pathways to your future. I have no regrets about my career choice and can truly say I thoroughly enjoy what I do.”
