Watch each other's boats. Head out together. Stay in touch in between.

DockNeighbor is the app for the people who share your dock — shared alerts when something's wrong, float plans when someone's heading out, and a place to talk the rest of the year. With 24/7 monitoring built in, not bolted on.

  • 🆓 Free to join, even with no hardware
  • 🤝 Your neighbors, your choice
  • 🛠️ Off-the-shelf sensors

The idea

Nobody boats alone.

Someone checks your lines after a blow. Someone tells you the pedestal tripped on B dock. Someone waves you off when you leave on Friday and asks how it went on Sunday. Every dock already does this — it just runs on luck and who happens to be standing there. DockNeighbor gives that instinct sensors, float plans, and one place to talk.

Watch together

An alarm that reaches more than one phone

The difference between a monitoring box and a neighborhood is who finds out. Water in the bilge, a dying battery, a dropped pedestal, an anchor starting to drag — DockNeighbor watches the failures that happen quietly, then tells the people close enough to do something.

1

2:14 a.m. — water rises

A high-water sensor in the bilge trips. The app knows in seconds, whether or not anyone has it open.

2

2:14 a.m. — the Dock hears it

You get the alert three states away. So do the neighbors you picked — the ones actually at the marina tonight.

3

2:21 a.m. — someone is aboard

Not because they own the boat. Because they're your dock neighbor, and this is what the dock does.

Free plans reach you and one friend; paid plans reach up to five. You pick which friends, and which alarms each of them gets.

Cruise together

Going somewhere is better when the dock knows

The other half of what a dock does: everyone knows who's heading out, where, and when they're due back. Half safety, half the best part of the season.

🗺️

Plan it on real depth

A route is only as good as what's under it. Plan on depth tiles and real channel lanes, for the draft you actually have.

📋

File it with your Dock

The oldest safety practice on the water, and the one most often skipped — because telling somebody is a chore. When your Dock is already in the app, it isn't.

📍

Let them follow along

Family watching a passage, a partner meeting you at the ramp, a neighbor who wants to know you got in. You pick who.

The trip planner, float plans and location sharing are in development — voyage history is live on Voyager today. Everything here is included on your plan the day it ships.

Stay in touch

A dock is a year, not a weekend

Most of what a dock talks about isn't an emergency. It's the season — and it's the reason you know these people well enough to trust them with your boat in the first place.

Spring

Who's splashing when, whose bottom paint is worth copying, and which yard is running behind.

Summer

Who's out this weekend, where the anchorage was empty, and who's around to take a line.

Fall

Haul-out dates, the blow that's coming Thursday, and whose cover needs another strap.

Winter

Storage questions, the projects nobody finishes, and someone walking the yard in February.

The community forum is live today, with single sign-on from your account. A feed scoped to just your own Dock is a fast-follow after relaunch.

How it actually works

Aboard, the app talks to your sensors directly. Away, the cloud keeps watching and does the reaching out. Off-the-shelf hardware, no proprietary black boxes.

How DockNeighbor worksSensors and the water valve on the boat talk to the app directly over the local network, and report to the DockNeighbor Cloud over the internet. The cloud pushes alerts to you and the neighbors you choose, anywhere, and closes the valve automatically on a flood alarm.⛵ On boardOff-the-shelf sensors on the boat's Wi-Fi📍 GPS · anchor & security🔋 Battery monitor⚡ Shore power🌊 Flood sensors💧 Water valve (city water)📱 Your app, aboardLive readings and control on theboat's own network — no internet needed☁️ DockNeighbor CloudAlerts, remote view, history —no hub hardware required📲 You, anywherePush alerts on every plan ·remote view · shared with your crewLocal Wi-Fi — instant, works offshore & off-gridreports in secondspushFlood alarm?

Two independent paths: aboard, the app talks to your hardware directly; away, the cloud watches, alerts, and acts. Lose the internet and the local alarms keep running.
For marinas

A dock is a place before it's a group

Marinas, yards, mechanics, and management companies get one account, real roles, and every boat in their care in one app — plus long-range sensors and shared hubs that cover a whole facility instead of one slip.

Free to join. Plans follow the boat.

A neighbor who watches but owns no hardware joins at $0 — that's the point. Plans are per boat, a bit like Plex: the owner subscribes once, and everyone the boat is shared with gets its features. And while we’re in beta, every hosted plan is free — no card required.
