About
CROWD-SOURCED CONDITIONS
See wave height, weather, debris, wildlife, and Coast Guard sightings reported by other boaters nearby — updated live, with a clear distinction between a report at someone's actual position and one pinned to a spot on the chart.
ROUTE CHARTING
Draw a route by hand, drop waypoints with a tap, or import one straight from Navionics as a GPX file.
FLOAT PLANS
Log your vessel, your crew, departure and ETA, and a rescue authority contact before you leave the dock — then share it.
LIVE POSITION SHARING
Share your real-time position and ETA with the crew and contacts on your float plan while you're underway.
WEATHER, TIDES & ALERTS
NWS weather alerts and a live NOAA tide curve for your nearest station, right on the chart screen.
BOAT & CREW PROFILES
Save your boat's details and your regular crew once, then reuse them across every trip.
