Azimuth Systems Ltd is a UK company that builds specialist exam preparation apps for maritime officers. Our products are The OOW Bible for deck officers studying the MCA OOW Unlimited certificate (STCW A-II/1) and The EOOW & ETO Bible for engineering officers (STCW A-III/1 & A-III/6).
We make two apps: The OOW Bible for deck officers and The EOOW & ETO Bible for engineering officers. Both include a Part A exam simulator, AI oral examiner, spaced repetition flashcards, structured lessons, and a quick reference library — all working fully offline.
The OOW Bible is designed for cadet officers and watchkeepers preparing for the MCA Officer of the Watch Unlimited certificate. The EOOW & ETO Bible is for engineering cadets and officers preparing for the MCA EOOW and ETO certificates. Both are also useful as quick reference tools for qualified officers on watch.
