Maarten Janse was born and raised in Zeeland and has a deep connection with the sea. After completing his Bachelor of Maritime Officer degree at the Maritime Institute De Ruyter (2002–2006), he began his career as a 4th officer on the cruise ships of Holland America Line. In the years that followed, he progressed to 1st officer and gained worldwide experience in ship navigation and maneuvering, delivering safety training to crew in various emergency roles, organizing emergency drills, and leading teams responsible for the maintenance of lifesaving appliances and fire detection, prevention, and firefighting systems.
In 2022, Maarten made the transition to a shore-based position, wishing to spend more time with his family while sharing his extensive hands-on experience with others. As a Senior Maritime Instructor at DRTC, he delivers training such as AFF, PST, PSCRB, FRB, ECDIS, GWO, and MCRM, as well as modules within ship management. His trainings are realistic, practice-oriented, and always linked to real-world situations. Maarten holds the certificate of competency as Master Mariner (all ships) and Firefighting Crew Member, and is a certified CAE MCRM instructor, making him a specialist in maritime incident response and teamwork.
Maarten has a strong passion for sharing knowledge. As a black belt holder in Kyokushin karate, he enthusiastically taught both youth and adults for many years. That same energy, dedication and attention to the participant characterize his approach in every training he delivers.
Born and raised in Zeeland, Michel de Pooter carries the sea in his heart. From a young age, his parents took him along on their sailing boat, instilling in him a deep-rooted love for the water and maritime life.
After completing his Maritime Officer training, Michel began his career as a 4th Officer with the cruise ships of Holland America Line. In the following years, he rose through the ranks to Staff Captain, gaining a wealth of experience in leadership and ship operations on board cruise vessels worldwide.
In 2025, Michel chose a new course: a shore-based position that allowed him to spend more time with his family while sharing his extensive hands-on knowledge with others. As Senior Maritime Instructor at DRTC, he delivers a variety of maritime training programs and is also regularly involved in the preparation and development of courses at the office.
