One chart — live AIS traffic, NOAA charts, SST and seafloor relief, honest weather, and an AI Captain's Briefing that scores your departure windows. The map behind this text is live right now.
255,000 vessels · 1,480 harbors · live positions — no account needed
Recorded traffic from last night playing back, a buddy link failing safe, real radar, real sea-surface temperature. Tap any map to explore it.
Scrub any window in the last 30 days, anywhere. Every dot is a real vessel from the recorded archive.
Share live position with people you choose. Freshness is always shown, never guessed — and when a buddy goes quiet, you know in seconds. This demo loops the exact behavior.
