Peace of mind while away
Your boat learns its own baseline over 90 days. We watch what's normal — and tell you the moment something drifts. Battery dropping faster, anchor moving, bilge cycling unusually often.
Built for liveaboards
Sleep at home. Your boat watches itself.
BoatMC is for liveaboards and seasonal cruisers who can't be on the boat every day. We learn your boat's normal, then alert you when something's off — battery dropping faster than usual, bilge cycling, anchor drifting, shore power lost. BoatMC is in guided private beta now while we prepare the dedicated onboard appliance edition.
Current pilots are guided directly by BoatMC support.

Why owners use BoatMC
Real alerts, not false alarms
VRM tells you the voltage. BoatMC tells you when the voltage is wrong for THIS boat at THIS time of year. Pattern-based, not threshold-based — so you don't get woken up at 3am for a normal night discharge.
Setup that doesn't fight you
Guided pilot setup with a preflight checklist that catches Cerbo MQTT misconfigs, portal-ID issues, and network blockers before commands are run. If setup gets stuck, BoatMC support reviews the install session and gives one safe next step.

🥧BoatMC appliance path (next)
Pilot support is intentionally guided while we harden the dedicated onboard appliance and confirm hardware coverage boat by boat.
Not sure? Walk through the setup finder — 30 seconds, no account.
How It Works
Three steps. Then your AI gets smart.
No complex installation. No programming. Connect your existing hardware and let your boat teach itself what "normal" looks like.
1
Install
Current private pilots use the guided installer with BoatMC support watching the session. The next customer path is a dedicated BoatMC onboard appliance, so installs become predictable instead of depending on each boat's Cerbo/Linux quirks.
Existing beta installs remain supported. New broad self-serve installs are being tightened around the appliance path before wider release.
2
Learn
Every 10 seconds, a snapshot flows to the cloud. Over 90 days, BoatMC builds baselines — what "normal" looks like for your specific boat.
Morning voltage patterns. Typical solar yield by season. Overnight draw rates. Engine temp curves. Fuel burn profiles. Anchor swing radius. Your boat's unique fingerprint emerges from the data.
3
Ask
Connect your own Claude / ChatGPT / Gemini via MCP — copy-paste setup, no API keys from us needed. Your AI now has 18 boat-aware tools and months of your specific boat's context.
The difference between "your battery is at 12.8V" and "your battery is 0.3V below your 90-day morning average, declining since shore power dropped 3 days ago, you have ~2 days at current draw."

AI Integration
Your AI is only as smart as the data behind it.
Same question, same boat, same AI — the only difference is context. BoatMC exposes your boat via MCP, the open protocol that lets Claude, ChatGPT, or any AI ask your boat real questions.
"Is my battery healthy, or should I be worried?"
Current beta answer:
Your house bank is at 12.8V. That's within the normal range for a 12V system.
Context-rich answer:
Your house bank is 0.3V below your 90-day morning average. It's been declining since shore power dropped 3 days ago. At current draw, you have ~2 days before 12.0V. Solar isn't keeping up overnight.
"How's my power budget looking for the week?"
Current beta answer:
Your solar is producing 340W and your battery is at 92%.
Context-rich answer:
Your average daily solar yield is 1.8kWh, but your overnight draw averages 2.1kWh. You're running a 300Wh daily deficit. At this rate your bank drops below 50% by Thursday. Either reduce overnight loads or run the genset for 2 hours.
"Where did we anchor last time we were in this area?"
Current beta answer:
I can see your current GPS position but I don't have any historical location data.
Context-rich answer:
You anchored at 18°27.3'N 64°37.1'W on March 12 for 3 nights. Wind was 8-12 kts from the east, swing radius was 45m. Bilge stayed dry, battery held above 12.6V overnight. Good spot.

BUILT ABOARD · SV BLUE MOON
A monitoring tool for cruisers, built by one.
BoatMC runs on my own cruising catamaran — SV Blue Moon — and has for months. Every panel, every alert, every AI tool you see here is something I either already rely on at anchor, or wish I'd had the last time something broke at 2am.
If something doesn't work on your boat, I'll personally help you fix it. Beta users get my WhatsApp.
