Deckhand reads the data already flowing through your Simrad, Lowrance, or B&G MFD — then translates it into maintenance intelligence a boat owner can actually use.
Impeller at 94% of expected service interval. Schedule within the next two trips.
Boats fail silently. Until they don't.
Your car tells you something's wrong. Your boat hides it behind six flashing gauges and a service manual written in 1994. The average recreational boater learns about a failing impeller, a dying battery, or a creeping coolant leak the same way — out on the water.
Deckhand is the quiet layer between the MFD you already own and the mechanic you'd rather not call.
Your MFD is a sensor array. We wrote the software that treats it like one.
Every modern Navico MFD streams a live feed over Wi-Fi — engine data, GPS, depth, wind, water temp. Deckhand subscribes to the signals that matter and ignores the noise.
Walk onto the boat, open the app.
Deckhand discovers your MFD on the helm Wi-Fi automatically. No pairing screen. No serial numbers to type. No 'find my device.' It's just connected.
Every signal the bus carries.
Engine, GPS, wind, depth, water temp, trim, fuel — Deckhand subscribes to what matters and persists it locally the moment it arrives.
Your boat's baseline becomes visible.
A few trips in, Deckhand knows what 'normal' looks like for your rig. Deviations stop being noise and start being signal.
Told before, not after.
Impeller creeping past its interval. Voltage sagging only on cold starts. Coolant trending warmer trip over trip. You hear it at the dock.
Three surfaces. One source of truth.
Live engine telemetry
RPM, oil pressure, coolant, fuel flow, voltage, trim — rendered as something you'd actually want to look at.
Automatic trip logging
Engine on, GPS moving — Deckhand writes the log. Fuel burn, hours, route, weather, all of it.
Predictive maintenance
Impellers, oil changes, zincs, belts. Tracked by engine hours, not guesswork, and flagged before they fail.
Quietly watching, so you don't have to.
We're onboarding San Diego boat owners for the spring beta. No hardware. No subscription until it works.
