Sail Bay Area displays high-resolution marine navigation charts for sailors and boaters in the San Francisco Bay Area. The application uses NOAA vector charts that have been converted into huge, high-resolution images. The images have been highly optimized for fast, efficient panning and zooming. When viewing charts, the application will obtain GPS coordinates from your iPhone or iPad (if available) and will plot your location on the chart. Your speed and bearing will also be shown.The charts are based on NOAA data as of November 2012. The following charts are included:1. 18640 - San Francisco to Point Arena2. 18645 - Gulf of the Farallones3. 18649 - San Francisco Entrance4. 18650 - Candlestick Point to Angel Island5. 18651 - San Francisco Bay Southern Part6. 18653 - Angel Island to Point San Pedro7. 18654 - San Pablo Bay8. 18656 - Suisun Bay9. 18680 - Point Sur to San Francisco10. 18682 - Half Moon Bay11. 18685 - Monterey Bay12. 18686 - Pfeiffer Point to Cypress PointThe charts are stored on your device for off-line viewing.While the charts are based on NOAA data they should only be used as a navigational aid and not as a substitute for navigational equipment required under law or marine regulations.Special thanks to Bob Webster for converting the charts to PNG format.
