i-Boating:Marine Navigation Maps Nautical Charts

i-Boating charts and voice guided routes for confident navigation

i-Boating: Marine Navigation Maps Nautical Charts brings a chartplotter style toolkit to the water, bundling nautical, river, and lake maps into a single, feature rich package for boating, sailing, paddling, and fishing.

The headline feature is route guidance with spoken prompts. Plan a course, and the app can nudge you along with voice cues, a welcome aid when your hands and eyes are on the helm. Chart display supports course up orientation, so your map aligns with your heading, and tide charts plus current predictions help you time passages and approaches more wisely.

Route planning is flexible. You can create routes and waypoints on the map or bring in existing trips using GPX or KML files, useful if you already rely on other planning software or share tracks with friends. Marine AIS support via NMEA adds situational awareness by overlaying vessel data on your charts.

Under the hood, GPU accelerated vector NOAA and ENC charts keep labels legible by holding text upright even as you rotate the device. Anglers will appreciate lake depth shading and safety depth contours, along with high definition 1 ft or 3 ft contour maps for selected lakes that make it easier to target structure and drop offs.

There are a few caveats. The HD lake contours are not universal, so coverage varies by lake, and AIS features depend on an appropriate NMEA data source. That aside, the package covers the essentials for navigation and chart plotting across coastal waters, inland rivers, and lakes.

Pros:

- Offline nautical, river, and lake charts with vector rendering

- Voice guided route assistance and course up orientation

- Tide and current predictions for trip planning

- GPX and KML import for routes and waypoints

- AIS support and detailed lake depth shading with safety contours

Cons:

- HD 1 ft or 3 ft lake contours available only for selected lakes

- AIS features require a compatible NMEA feed
