YOUR BOAT CHANGES THE PLAN
A course worth checking.
Put your boat’s draft, departure time and clearance margin into the route check. See the shallowest point, estimated time underway and reported restrictions before you commit to the day.
Plan your route Warnings stay attached to every route. Verify bridge clearances locally.
WATCH THE SKY. PICK YOUR WINDOW.
The weather moves. See what’s coming.

Grounding watchActual app capture · setup before tracking
Know what’s beneath you.
Explore depth shading and contours, check a route’s shallowest point and review tide-adjusted clearance for your boat. Opt into grounding watch for checks around your GPS position.
Explore the actual Keys coastline and modeled depth shading. Zoom into Key West, Marathon or Islamorada, then work out the charted depth your boat would need below.
Wildlife records are dated observations, not live tracking.
