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 Chart coverage and warnings stay attached to every result. Verify bridge openings and actual clearances separately.

WATCH THE SKY. PICK YOUR WINDOW.

The weather moves.
See what’s coming.

Radar over the coast. Clouds from space. Rain and thunder through the hours ahead.

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.

Checks depend on chart coverage, tides and usable GPS. Review the reported gaps and warnings.

EXPLORE THE FLORIDA KEYS

Real islands.
Real water. A closer look.

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.

Draft 2.5 + clearance 1.0 − tide 0.5 = 3.0 ft minimum charted depth

Check your boat and route
THE FLORIDA KEYS
Full map
DEPTH KEY FEETBelow → Above requirement
  • Below 3.0 ftToo shallow for chosen margin
  • 3.0–5.0 ftJust above chosen margin
  • 5.0–15.0 ftMore modeled clearance
  • 15.0+ ftDeep modeled water
Gray water: depth unavailable

Red is below your chosen modeled-depth requirement. Green is just above the chosen requirement; light blue and navy indicate deeper modeled water. No color verifies safe passage. The example tide assumes a common datum; verify chart depth and local tide before navigating.

Loading real map and depth tiles…

Real coastline: OpenFreeMap / OpenStreetMap. Depth tiles: NOAA NCEI where available, with AWS Terrain Tiles fallback. Modeled depth is not a verified navigation chart; source resolution and vertical datum vary. Red marks modeled depths below the draft-plus-margin requirement after the example tide adjustment. This assumes a common vertical datum and does not establish passable water. Use route checks with reported chart coverage, local tides and your depth sounder.

THERE’S MORE TO THE DAY THAN WEATHER

Find your spot.
And the stops along the way.

Dive spots. Boat ramps. Fuel docks. Somewhere to drop anchor. Explore the places and local details that turn an idea into a day out.

  • Reefs, dive spots, marinas and coastal places
  • Fuel stops, ramps and available activity reports
  • Dated shark and jellyfish observations, with sources
Find your water

Wildlife records are observations, not live animal tracking. Activity reports depend on available coverage and freshness.

YOUR QUESTIONS. YOUR WAY OF ASKING.

Your water knowledge.
In your AI workflow.

Ask Gillby in the app, or explore a connection to the assistant you use. Coastal tools bring forecasts, tides, places and source details into the conversation.

High water.
Right on your radar.

The tide is part of the plan.

Check tide timing alongside your launch, dock and route before choosing when to go.

Explore tides in Gillby Design preview for the upcoming iPhone experience. King-tide notifications are a proposed feature; this mockup does not indicate a current warning or automatic alert service.
