Community marine data

Every boat makes the forecast better.

Matey turns your boat into a weather station. See all your instruments on one live dashboard, record every trip automatically, and help build the most accurate live picture of conditions on the water — anonymously, with your crew.

The conditions network

PREVIEW — NOT YET LIVE

See the water through every mate’s instruments.

Boats contribute anonymous wind and pressure observations to a shared live map. Rotating MT- IDs, never names — and every added boat makes it better for everyone.

Illustration — sample observations, clearly labelled until the network launches.

What it does

One connection. Every instrument. Better forecasts.

Matey Bridge

A plug-in gateway for any brand of instruments. Five-minute install — read-only, works alongside your electronics.

Live dashboard

Wind, depth, pressure, position and more, with source, freshness and measured-vs-calculated provenance on every value.

Trips, recorded

Every trip logs itself — distance, speeds, wind, track. Export GPX, CSV, or JSON straight from the share sheet.

Route planner

Water-only routes that respect your keel draft, planned on real charts.

Conditions & alerts

Your instruments beside the nearest official station, official marine warnings and your own threshold alerts in one feed.

How it works

On the water in three steps.

1

Create your account

Sign in with Google or Apple — no passwords to manage.
2

Connect your boat

Plug in the Bridge; the app finds it on your Wi-Fi and shows live data instantly.
3

Share the water

Opt in to the anonymous conditions network and see what your crew sees.

See a live boat

The actual Bridge dashboard, embedded.

This is the same web app your Bridge serves on the boat — running live below. Switch tabs, watch the instruments update, open the Weather panel.

matey-bridge · live dashboard

Live dashboard Point this at a running Matey Bridge to embed its live dashboard here. Set MATEY_BRIDGE_URL to your Bridge's public address (its built-in simulator keeps the dashboard populated).

Read-only — the dashboard only ever listens to the boat network.

The design

Every screen, designed before it was built.

These are the actual working boards from Matey's design source — the same files the app and this site are built from. Open any card, or play the whole set as a deck.
