About MIOS
Built on the water,
not in a slide deck.
MIOS started as a way to keep every trip and every NMEA 2000 reading from our own boat—then turn that history into charts, maps and plain-English answers after you dock.
The story
Listen first. Make sense of it later.
High Star is a small shop. We run MIOS on real outings with Garmin chartplotters and Yamaha engines on NMEA 2000. Deckhand was the first hardware bet: a listener on the backbone that never talks back to the bus, so the helm you already trust stays exactly as it is.
From there we built the MIOS app—Domain-style instruments, trip replay on the Nav tab, and uploads to a VPS so trips survive when the phone leaves the boat. The iOS app, the Pi 5 helm unit, and the Vessel surface on the MFD are different faces of the same measured data, not three separate products.
Journal is where trips become useful ashore. You ask what happened between two times, how the engines looked on the way home, or to see the whole outing on a marine chart. The server paints measured charts and chart-backed trip maps from the same N2K history; the app shows them beside a written answer—no invented numbers, no fake screenshots.
Project notes, decode maps, and the living backlog for the team stay on skunktech.net/mios. That hub is for builders and collaborators, not the beta signup page.
Project milestones
Where we are, what is next.
-
2024 – 2025 Shipped Trip logging and replay
N2K history on the VPS, replay chrome on iOS, SkunkMarine live view, and measured Yamaha CLP decode on the helm Pi. Every outing is a first-class trip with SOG, depth, temps and twin-engine data when the bus provides it.
-
2025 Shipped Journal, charts and trip maps
Ask questions after a trip. Attach measured waterfall charts and marine-chart maps colored by time, speed, depth or water temperature—rendered from real GPS, cached on the server, pinch-zoomable in the app.
-
Now In beta Deckhand V1 kits
Hand-built listeners for boaters who will run them on real seasons and tell us what breaks. Each beta box ships the module, an N2K drop cable, and USB setup lead—see what's in the kit on the home page.
-
Next In progress MIOS Helm Unit on the MFD
Fanless marine computer with MIOS springboard on Garmin OneHelm: modern engine and instrument tiles, trip marks, and Salty Offshore weather beside your existing plotter apps.
-
Ahead Planned Richer questions across seasons
More Journal depth—comparing trips, spotting trends, and plain-English summaries grounded only in measured data from your boat, not generic boating advice.
