AUA+ · See more. Decide better.
AUA+ adds nautical guidance, search, depth and richer weather context — exactly when you need it on the water.
AUA+AUA+
More context. Only when it genuinely helps.
The same tools as in the app, explained with real screenshots.
Search
You find the right place.
Search for a port, restaurant, activity or facility and open the result directly on the map.
Depth
You know what is under the hull.
Depth and under-keel clearance use the active boat data to highlight situations that need attention.
Clearance
You see whether it fits.
Bridges, passages and boat height are combined to flag air-draft constraints at the right time.
6-hour weather
You anticipate the next hours.
Wind, gusts, rain and temperature are grouped hour by hour in the same panel, directly at your position.
Radar, lightning & alerts
You see what is coming.
Rain radar, observed lightning strikes and deterioration alerts add context without turning AUA into a cockpit.
FREE OR AUA+
The essentials stay free.
AUA+ steps in when you want more context and guidance on the water.
