BoatKit’s chart is the common geographic surface for navigation and local context. Marine vector charts, buoys, restriction zones, AIS targets, ActiveCaptain points of interest, and tide and current stations can all be inspected without moving between unrelated screens. When live vessel sources are available, position, heading, depth, radar, route progress, and other underway data join that same chart.
Search understands supported marine places and chart features, coordinates, nearby AIS vessels, and indexed points of interest. A result opens where it belongs on the chart, so its details remain connected to the water, traffic, and restrictions around it. AIS targets can show vessel dimensions/speed and warn about potential collisions/close calls; tide and current stations provide their predictions in the location where they matter.
If your vessel MMSI is missing and an AIS target persistently matches your position and motion while underway, BoatKit can ask an administrator whether it is your own vessel. Confirm its MMSI to remove the self-target and its collision warnings, or dismiss the suggestion while keeping traffic visible. Onboard AIS and this prompt work locally without internet access. Learn how to set your vessel MMSI.
Charts aboard and away
Downloaded charts and supporting data can live on the BoatKit host and are rendered directly in the browser, keeping the core chart useful without a live internet connection. A tablet can supply its own GPS for a standalone chart experience, while NMEA and marine-network integrations add vessel sensors, AIS, radar, and other context as the installation grows.
When the vessel is connected, BoatKit Cloud provides the familiar chart remotely rather than substituting a separate fleet-style map. Coverage and available layers depend on the chart data licensed and installed for the region.
Chart updates stay within the dataset version supported by the installed BoatKit release. This keeps saved coverage and its updates compatible while new datasets are tested separately. Downloaded coverage remains available offline.
The chart corner identifies contributing data providers for the displayed area. Select Map data for source and licence notices; saved-chart notices remain available offline. Older overview charts explain when their original provider coverage is unavailable. Learn how to check chart sources.
BoatKit budgets chart loading and rendering across open chart views. On memory-constrained devices, a broader chart can remain visible while detailed tiles or survey overlays are limited. An on-chart notice makes that limit visible. Understand chart detail limits.
Where tiled ACE survey coverage is available, BoatKit loads smaller survey sections for close chart views and chooses detail as you zoom. Wider views hide the survey overlay; zooming back in restores available surveys. Survey dates and depth inspection stay available, and downloaded sections work offline. Base charts take priority when a device runs short of chart memory. Learn about ACE survey detail.
