DCOne (Deck Cadet One) is a free platform built by cadets, for cadets. Our goal is simple: to make training easier by providing clear, practical resources that support you at every stage of your cadetship.

Like a compass guiding a ship, DCOne helps you stay on course. With Knowledge, Community, Experience, and Support as our cardinal points, we bring together revision guides, checklists, templates, and real-world insights drawn from the experiences of cadets who have been through the same challenges.

Whether you’re just beginning your first voyage or preparing for Phase 5, our resources are designed to be accessible, reliable, and rooted in the realities of life at sea and in college.

Our mission is to share knowledge, build confidence, and keep your journey steady and informed — so you can focus on what matters most: becoming a skilled and capable officer of the watch.

Welcome aboard.
