Everything it watches, and who it tells
A sensor can tell you something is wrong. DockNeighbor makes sure the news reaches you first, wherever you are — and, only if you want and only if it keeps going, one person close enough to do something about it.
Your phone first. A friend only if it keeps going.
Every alarm reaches you, whether or not the app is open. If it is still going five minutes later and you have not tapped "I've got it", it reaches the friend you named — because your phone is the one furthest from the boat. A dragging anchor skips the wait. A hose on a sensor never wakes anyone but you.
- You choose who: friends you have added, and only the ones you mark as notifiable. Nobody sees your boat because they happen to share a marina.
- It works on the free plan: Free carries 10 friends and fans an alarm out to one of them; Dockside has unlimited friends and still reaches one. Weekender and Voyager reach up to five.
- They see what matters: what tripped, when, and where the boat is — not your account, your billing, or your other boats.
- Crew sharing is the deeper kind: share the boat itself with up to 5 crew members on Weekender (10 on Voyager), with three roles — full admin, monitor and control, or view-only. Your neighbor can check on the boat without being able to open the water.
Water where it shouldn't be
High water is the failure every boat eventually meets — rain past a failed cover, a weeping stuffing box, a pump that quietly lost the battle. A leak sensor at the height you choose, or a sealed float in the bilge, and the alert is on your phone the moment water shows up.
- Nothing in the way: each sensor reports by long-range radio to a DockNeighbor Station — no Wi-Fi to drop in the bilge, no third-party cloud to go down at the wrong moment, and years on one battery.
- Free on every plan: bilge and flood alarm delivery is immediate on Free and always will be. Alarms are never behind the paywall.
- On city water, it acts: a dock hose is unlimited pressurized water one fitting away. With a LinkTap valve on the hose (Weekender and up), a flood alarm closes the valve on its own.
- Real-time flow metering: see how many gallons are moving through your plumbing, and set a ceiling so a runaway line shuts itself off.
Still where you left it
DockNeighbor watches where the boat is and whether it has moved — from your phone's GPS on the free plan, or from a GPS tracker aboard that reports through the station.
- Anchor alarm, free on every plan: set a swing radius and you hear about a drag — in the app aboard, and from the cloud with the app closed. Your neighbors hear about it too.
- Away Mode: tell DockNeighbor whether the boat is Aboard, Away or at Anchor, and alerting changes with it — movement that's normal at the dock becomes worth waking someone for when nobody's there. Choose Away and, if the boat leaves where you left it, you know. (Away is Dockside and up.)
Power, shore power, and cold
A dead battery is a dead bilge pump. Lose the 12V system and you lose the pump, the fridge, and your safety electronics — usually without anyone noticing until it matters.
- Voltage, tracked: a battery sensor on the bank graphs it over time and catches a deep discharge early, including a sudden drop.
- Shore power status: a plug in a cabin outlet, a clamp on the shore-power line, or a sensor at the inlet — know the moment a marina pedestal drops AC, the failure that quietly ends charging and refrigeration for a whole dock at a time.
- Cold: temperature from the sensors that carry it, so a coming freeze is a warning rather than a spring surprise.
- One box for most boats: battery, bilge float and shore power from a single unit on the house bank.
Works through the marina, or on its own
The sensors don't need the boat's Wi-Fi, and they don't need you aboard. They talk by long-range radio to a DockNeighbor Station, and the station does the rest.
- At a marina with a station: the sensors are the whole install. Scan them in and they report from the day you arrive.
- Anywhere else: bring your own station aboard. The 4G model takes a SIM and needs nothing from the dock.
- Through an outage: the station keeps watching while the internet is down and catches up when it's back.
History that tells the story
A single reading says "fine." A week of readings says "your charger is slowly losing the battle."
- Kept for you: hosted history you can see from anywhere, on every plan — 1 year on Free, 2 years on Dockside, 3 years on Weekender at ~30-second resolution, and 5 years on Voyager.
- CSV export: Weekender and Voyager export your history for spreadsheets, insurance, or your own analysis.
Affordable sensors
Sensors you buy once and own, that run for years on a battery. Nothing rented, nothing marine-priced.
