Witherbys is adding a new tool to its maritime knowledge arsenal: a floating research lab. The MV Sea Ranger, set to join the fleet in 2026, isn’t just a vessel—it’s a mobile classroom, testing ground, and data hub rolled into one. This isn’t about adding another ship to the sea; it’s about rethinking how maritime knowledge is built, tested, and delivered.
The Sea Ranger will bridge the gap between theory and practice. It will support Witherbys’ computer-based training programs, already in use on over 40,000 ships, and enable real-world testing of ECDIS transitions, S-100 developments, and maritime guidance. This isn’t just about updating manuals—it’s about ensuring they work in the real world, from the Lombok and Sunda Straits to the Suez Canal.
“Having previously served as a research vessel for the Schmidt Oceanographic Research Institute, including expeditions as far south as Antarctica, MV SEA RANGER offers proven capability for global operations. It carries over 1.2 million litres of fuel, giving it a potential range of more than 30,000 nautical miles.”
This isn’t just about range—it’s about reach. The Sea Ranger will enable Witherbys to test and refine its publications in real-world conditions, ensuring they remain accurate, practical, and relevant for mariners worldwide. It will support the creation of new editions, such as an expanded Suez Canal guide, and enable detailed study of ECDIS transitions and the latest developments in S-100.
But the Sea Ranger isn’t just a tool for Witherbys—it’s a collaborative platform. It will enable Witherbys to work with industry partners, such as ICS and BIMCO, to ensure guidance remains current and in line with international standards. It will also support research on emerging security issues, environmental compliance, and energy efficiency solutions.
This is more than a vessel—it’s a statement. It signals a shift in how maritime knowledge is developed, tested, and delivered. It’s a recognition that real-world conditions matter, that collaboration is key, and that maritime safety and efficiency aren’t just about rules—they’re about practical, actionable knowledge. The Sea Ranger is set to become a key player in shaping the future of maritime training, research, and safety.
