Guided by Real Sea Experience
Sumit Sinha is an officer who spent over nine years working at sea, coming from an experienced seafarer route. After successfully clearing his own rigorous UK Officer of the Watch Unlimited Safety Critical assessment on his first attempt in April 2026 — an exam conducted for the first time in history — Sumit developed this platform along with his fiancée, an experienced software developer, to bridge the gap between textbook theory and the high-stakes reality of the digital exam.
The OOW Safety Critical Mock Quiz is built by a mariner, for mariners.
