You asked ChatGPT.
It answered confidently.
But what if it was wrong?
Maritime professionals worldwide are navigating MARPOL regulations, charter party disputes, CII compliance, and PSC inspections — using AI tools built for everyone, trained for no one in particular. ChatGPT is not wrong. But it is general. And in shipping, general is not good enough.
Where maritime professionals go today
ChatGPT knows a little about everything.
That is not enough for this industry.
General AI models are trained on broad internet data. They know what MARPOL is. They know what a charter party is. But knowing what something is, and knowing how it applies to your specific vessel, voyage, and situation — are two completely different things.
When a fleet superintendent asks about excess bunker claims on redelivery, a general AI gives a textbook answer. It does not know your charter party clause, your fuel grade, your voyage days, or your bunker survey figures. It cannot draft the claim letter. It cannot calculate the monetary value. It fills the gap with confident-sounding generality.
Training data is too broad
General LLMs are trained on everything — news, code, social media, encyclopedias. Maritime regulations, IMO circulars, MEPC resolutions, and technical guidance notes are a fraction of a fraction of that data.
Shallow regulatory depthNo operational reasoning
A superintendent’s question is never purely regulatory. It is regulatory + operational + commercial + vessel-specific. General AI cannot hold all of that context simultaneously and reason across it.
Technically correct, operationally insufficientConfident when uncertain
LLMs are trained to sound authoritative. They do not say “I don’t know” — they extrapolate. In maritime, an extrapolated answer on PSC deficiencies, CII calculations, or demurrage clauses can cost serious money.
Liability dressed as guidanceWhat if there was an intelligence built from the ground up for the maritime world — that thinks, acts, and reasons the way a 30-year maritime veteran does?
Not a chatbot that knows about shipping. An intelligence carrying the combined knowledge of a Master Mariner, Chief Engineer, Fleet Superintendent, DPA, and Commercial Manager. One that understands the difference between a laytime calculation and a demurrage claim. Between CII rating and CII correction. Between what the regulation says and what it means for your vessel.
