Your maritime AI expert — trained on SOLAS, MARPOL, ISM Code & technical manuals. Built for seafarers, captains, and marine engineers. Ask anything.
Your AI-powered maritime expert, trained on SOLAS, MARPOL, ISM Code, and technical marine engineering documentation. Built exclusively for seafarers, captains, and marine engineers.

Instantly query IMO conventions, SOLAS chapters, MARPOL annexes, ISM Code requirements, and STCW standards. Get accurate, referenced answers -- not generic AI guesses.
TECHNICAL TROUBLESHOOTING
Diagnose machinery faults, trace electrical systems, and resolve engine room issues with an AI that understands marine engineering terminology and technical documentation.
COC & CERTIFICATION EXAM PREP
Prepare for your Certificate of Competency exams with an AI tutor trained on maritime examination topics. Practice oral exam questions for Deck and Engine departments.
BUILT FOR LIFE AT SEA
Handover understands your world -- from bridge watchkeeping procedures to auxiliary engine maintenance, from cargo operations to port state control inspections.
Whether you're a Chief Engineer troubleshooting a purifier, a Third Officer preparing for COC orals, or a Captain reviewing ISM procedures -- Handover is your always-available maritime AI assistant.
Trained on real maritime technical documentation. Designed by seafarers, for seafarers.
WHY HANDOVER AND NOT A GENERAL AI ASSISTANT?
General AI assistants give plausible-sounding answers. Handover is trained on actual maritime technical documentation -- SOLAS convention chapters, MARPOL annex requirements, ISM Code procedures, and STCW certification standards. When you ask about fire safety equipment on a tanker, you get the SOLAS Chapter II-2 reference, not a vague summary. When a marine engineer asks about purifier alarms, you get the specific diagnostic steps, not generic advice to consult a technician.
