Works with one boat
Forecast
Wind, gusts, seas, freezing spray and sea ice along your own grounds, hour by hour, from the 2.5 km ECCC model. Official ECCC warnings and the marine forecast text sit right beside it.
Fleet weather for commercial harvesters
Every boat becomes a weather station, and the whole fleet sees what the forecast missed.
Mauzy Marine gives each boat a 2.5 km forecast for its own grounds, puts the official warnings in front of the crew, and checks the forecast against what is really happening on the water.
Running now on a demo fleet with the live Environment and Climate Change Canada (ECCC) forecast.


It starts useful on one boat. It gets better with every boat that joins.

Coming next
The skipper’s phone will supply position and motion, plus one tap condition reports. A marine sensor kit follows, to log true wind, pressure and sea state every minute. On the demo fleet, boat reports are simulated.
Grows with every boat
Every boat is a node on a live map, linked to its neighbours. You see what the boats ahead are reporting, and how the forecast is holding, area by area.
Every screen below is the working app, captured today on the demo fleet with the live forecast. Pick a view.

Each boat is a node coloured by the conditions on its grounds. Tap one for wind, seas, freezing spray, the official marine forecast and the days ahead.
Demo fleet. Boat names, positions and boat reports are invented.
Off Labrador there are very few buoys and stations, so nobody knows where the forecast is wrong. Mauzy Marine compares what the model said with what was measured at the ECCC coastal stations, and with what the boats report, area by area.

A night look that keeps your eyes dark adapted, and a day look you can read in sun. Drag to compare.



The same fleet on a phone, laid out for one hand: the map, the forecast, the fleet and Ask, which answers in plain words and draws a chart or a table when you ask.
One purchase puts a whole fleet on the map, inside a group that already trusts each other.
Which boats are out, which are in port and when each is expected to land, so the plant can plan with more than a guess.
Conditions flow between the boats in your group. Nobody outside it sees your positions.
A running log of forecast against reality that shows where the models struggle on your coast.
Software first. The phone is the sensor. Hardware comes when you want more.
Available now on a demo fleet
The forecast for your grounds, official warnings, the Mesh, forecast against reality, alerts, the AI crew briefing and the shore dashboard.
