It’s 3 a.m. Anchored in a cove you’ve never seen.
Something woke you up.
You lie there in the dark.
“Hey Bosun — are we okay?”
“We’re fine, Captain. Ten metres of water. Anchor hasn’t moved in four hours. Wind’s picked up to 18 knots from the southwest. Tide’s rising — one more hour to peak. Bilge is dry. Everyone’s aboard. Go back to sleep.”
That’s what this is.
It knows your crew by name. It watches the boat while you sleep. It remembers every passage, every fuel burn, every squall you rode out. It’s the AI crew member you’ve always wanted — and the first one that actually works on the boat you already own.
And yeah, it’ll turn on the cabin lights. That’s the least of it.
Ask in natural language. Get answers from your actual instruments. Or don't ask — Bosun will tell you when something matters.
On first boot Bosun scans the NMEA 2000 bus and builds itself around whatever it finds aboard.
On first boot, Bosun scans your NMEA 2000 bus and figures out what's connected — Fusion stereo, CZone lighting, digital switching, whatever your boat has. Then it builds voice commands around it. "Dim the salon lights and play some music."
Bosun doesn't wait for you to ask.
Bosun doesn't wait for you to ask. Depth shoaling at anchor? It tells you. Barometer dropping fast? It flags it. Voltage sagging overnight? You'll know before the bilge pump does.
Planning a crossing? Bosun monitors your route weather, tracks AIS traffic, calculates CPA on approaching vessels, and alerts you to changing conditions. Watch-by-watch briefings. Wind shift warnings. Swell forecasts. It's the crew member standing watch while everyone sleeps.
Camera coverage with crew awareness, face recognition, and security monitoring. Knows who's aboard and where. Detects motion when the boat should be empty.
Say “Bosun” and ask. It knows who's talking.
Knows who's talking. Captain gets full access. Crew gets crew-level commands. Strangers get nothing. No setup — it learns your voice in 30 seconds.
Every answer comes from your actual instruments.
"What's our depth?" "How's the wind?" "Check the batteries." Anything on your NMEA 2000 network — depth, wind, speed, engine temp, fuel, tanks, voltage — answered in natural language, under a second.
The longer it runs, the more it knows about this particular boat.
"Bosun, log an oil change." Done — timestamped, stored, searchable. "When did we last run the watermaker?" It knows. No more scribbling in a soggy logbook.
Bosun learns your boat over time. Fuel burn rates, typical passages, power consumption patterns, anchor drag history. The longer it runs, the smarter it gets. Your boat's institutional memory.
Edge-first, cloud-enhanced. Built for 2,000 miles from the nearest cell tower.
Dial the personality from dead serious to quick-witted. Bosun adapts to how your crew actually talks.
Question: How's the boat?
"All systems nominal. Port engine at 4.87 hours since last oil change. Bilge pump cycled twice, slightly above average. Worth a visual check."
"Oh, the boat's great. The port engine is 13 hours from an oil change I've mentioned three times. The bilge is cycling more than it should. And there's a towel on the lifeline slowly becoming a sail. But yeah. Everything's fine."
Question: Should we anchor here?
"Depth 14 feet, tide dropping 3 more. You draw 6. Swinging room is adequate. Wind forecast steady through midnight. Holding ground is sand over mud — good."
"Depth is 14 feet, tide's dropping 3 more, and you draw 6. So mathematically, sure. Emotionally? The last time you anchored in a crosswind you invented four new words. Your call, Captain."
These are real questions crew ask — and how Bosun responds. Every answer comes from your actual instruments.
"What's the depth and is it getting shallower?"
"Depth is 4.2 meters and yes, it's shoaling. You've lost two meters in the last five minutes. Suggest altering course to starboard — the chart shows deeper water to the east."
"How are the batteries?"
"House bank is at 12.8 volts, 94 percent state of charge. Solar's putting in 185 watts. At this rate, you're good through the night without running the engine."
"What's that vessel off our port bow?"
"That's the motor vessel Pacific Trader, 180 meters. Making 12 knots on 045. CPA 0.3 miles in 12 minutes. You have right of way but I'd keep an eye on her."
"Log that I replaced the port impeller."
"Logged: port raw water impeller replaced at 1,247 engine hours. I've set the next replacement reminder for 1,747 hours or 12 months, whichever comes first."
"How fast are we going?"
"6.2 knots over ground. That's about 7 miles per hour, for the landlubbers."
"Bosun, it's getting rough out here. What do you think?"
"Well, barometer's dropped 6 millibars in the last three hours. Wind's shifted to the southeast and building — 24 knots now, gusting 32. Seas are 8 feet and stacking up. But hey, you wanted a dark and stormy. Now you've got one. I'd suggest a reef in the main and maybe a rum. Not necessarily in that order."
"Bosun, who's aboard?"
"Just Max — your golden retriever. He's in the salon, curled up on the settee. Hasn't moved in about twenty minutes. No human crew detected since you left at 14:30, and nobody's come aboard. Everything's quiet. You didn't think I only knew human faces, did you?"
"Hey Bosun, plan a passage from Brisbane to Vanuatu."
He pulls weather, marine forecasts, currents, and route conditions, then walks you through the window, the risks, and what to watch for. What used to take three apps and a chart table takes one question.
"Hey Bosun, translate what the harbormaster just said."
Whether you're clearing customs in Panama, taking a slip assignment in Palma, or asking for fuel in French Polynesia — Bosun listens, translates, and speaks back in your language. A live translator aboard, no phone, no app, no fumbling.
Voice passcode. Gesture unlock. AI-powered watch. When someone boards who shouldn't be there — Bosun goes silent, starts recording, and alerts you.
No subscription to start. No app to install. No screen to stare at.

Sovereign has no early-bird tier. Prices shown are hardware only; subscription billed separately.
Voice only. No cameras.
Adds vision — one camera.
Multi-zone voice + cameras.
Broader multi-zone coverage.
Any tier can be expanded. Add hardware to match your vessel's layout.
Bosun vision is an advisory aid — it observes, flags, and records. It does not replace a watchkeeper, guarantee detection, or ensure safety of life.
Voiceprints and faceprints are processed and stored on your boat, kept on the device itself. Camera vision, instrument monitoring, and security run entirely on your vessel's hardware. Voice AI uses encrypted cloud services for natural-language responses; offline fallback keeps the system usable off the grid.
