Modern boats know their engine temperature, fuel burn, battery state, location, heading, wind, AIS targets, and hundreds of other data points.

So why is the captain still the one doing all the translating?

Your boat knows:

One thing I didn't expect while building d3kOS was that the hardest challenge wasn't marine technology, AI, or even running local models on a Raspberry Pi.

It was creating a development process that kept AI from drifting.

After countless experiments, restores, and real-world testing on the water, I ended up creating an AI-focused SDLC and multi-LLM workflow that looks more like a software team than a single AI assistant.

I m building d3kOS, an open-source AI helm computer for the Raspberry Pi. It reads your engine data over NMEA 2000 and explains a reading, such as a rising coolant temperature, using your own manuals and sensor history.

The hardest design question has been what it should do when it isn t sure. Guessing confidently on a boat is worse than saying nothing. Right now d3kOS cites your manual and says plainly when it can t find an answer, and the safety features like SafeHelm are advisory only.

For boaters: when your instruments alarm, would you want a short answer, a step-by-step checklist, or a call a mechanic flag?
