Life of a Deck Cadet on a Merchant Ship: Daily Routine, Duties & Challenges

Have you ever wondered what life is really like onboard a merchant ship? For students planning to join the Merchant Navy, understanding the life of a Deck Cadet is an important step before choosing a maritime career.

A Deck Cadet is a trainee in the deck department who learns about navigation, ship operations, safety procedures, cargo operations and watchkeeping under the supervision of experienced officers.

Life at sea can be exciting and rewarding, but it also requires discipline, teamwork, adaptability and a willingness to learn. From participating in onboard training to understanding bridge operations, a Deck Cadet gradually develops the knowledge and practical skills needed for a future career as a deck officer.

In this guide, we explain the daily routine of a Deck Cadet, their duties and responsibilities, working conditions, onboard training and the challenges they may face during their Merchant Navy journey.

What Is a Deck Cadet?

A Deck Cadet is a trainee who works and learns under the supervision of qualified deck officers onboard a merchant ship.

The deck department is responsible for areas such as navigation, cargo operations, shipboard safety and other operational duties. During training, Deck Cadets observe experienced officers, participate in supervised activities and develop practical knowledge of ship operations.

Their responsibilities depend on the vessel, the training programme and the instructions given by senior officers.

Students interested in becoming Deck Cadets can explore the IMU DNS – Diploma in Nautical Science course at Training Ship Varren to understand the course and its place in the Merchant Navy career pathway.

The Directorate General of Shipping (DGS) provides official information and regulatory guidance relating to maritime training and seafarer development in India.
