Marine US is an iPhone/iPad universal application which gives you access to all the catalogue of nautical raster charts for USA (from NOAA Hydrographic Service material)
One of the biggest features in Marine GeoGarage service is that the charts are tied to the GeoGarage server : so no need to purchase or reload charts.
This means that the chart data will be always updated, constantly changing when NOAA releases new updated charts.
Marine US uses the embedded GPS to display the track of your boat in real-time on the multi-touch scrolling and zooming nautical chart.
Waypoint plotting with course and distance to the boat are the additional features of this basic but user-friendly mobile app.
Fixed a bug with the iOS version 7.2.1.
Ratings and Reviews
Works ok for the price but very basic
Would've given 2 stars but the low price makes it 3. Extremely basic. If u go to an area or zoom level that u did not view while connected, u can't use it while offline. Wish it would let u explicitly download an area.
Can't figure out how to delete waypoints. Only things I can do are view my current location and add a waypoint (with no notes or details). There is no other functionality that I can find. Does show actual buoy marker numbers tho which is better detail than the basic maps that come with a $600 Humminbird GPS.
Great maps of east coast waterways
Long Island sound and Chesapeake
Awesome alternative to paper charts
This is a great application. It gives me detailed NOAA charts, at any scale, of any location. I use it to study a route and plot waypoints before I take a trip. I use it as a backup on my boat. I use it so passengers can see where we are and where we're headed without messing with oversized paper charts or crowding me at the helm. I have the Furuno Navnet 3D on my boat -- as state-of-the-art as you can get in navigation. Sure, it can do a lot more. But for $5.99 (compared with $8,000 for the Furuno), Marine US is one heck of a wingman.
