GOOGLE Play : Marine Navigator Lite
Marine Navigator Lite is an Apps offline navigator using raster navigational charts (RNC's) to plot your position in real time. This way you can navigate with true copies of official paper charts on your mobile device. This lite version of the Marine Navigator provides the following basic navigation functions:
* real time positioning (instantly shows vessel's position and course on the chart)
* display of navigational data (position, speed over ground, course over ground)
* distance and bearing calculation
Marine Navigator Lite doesn't come with pre-installed nautical charts. Instead it is able to import BSB/KAP raster navigational charts (see menu->help for instructions). RNC's are available for free at various internet sites:
* http://www.nauticalcharts.noaa.gov (Suite of NOAA nautical charts that covers the coastal waters of the U.S. and its territories)
* http://www.openseamap.org (Openseamap charts are based on Openstreetmap data enriched with additional nautical information. The charts cover selected european coastal waters).
