SeaNav Nautical Charts
-------------------
You can choose what information to show on the map; Buoys, Lights, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. Turn off layers to de-clutter the display and only show what is important at the time. Once downloaded, charts are stored so you can use SeaNav to help navigate even when you have no mobile coverage. If you have our Boat Beacon app installed you can also view live AIS ship information on your SeaNav charts.

Plan and Sail Routes
-----------------
Use SeaNav to plan and sail routes. In-app tools let you measure distances and bearings and record waypoints on routes to sail. When you are out at sea, the app’s Sailing HUD shows your position on the route, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. An audible alarm sounds as you reach a waypoint and routing automatically moves onto the next waypoint.

Exploring Your Surroundings
------------------------
As you use SeaNav it will automatically download and store the charts for the area you are viewing. The level of detail on the charts changes as you zoom in and out. Tapping an object - buoys, lights, bridges, ships etc. - shows detailed information about them. A long press reveals a crosshair and a popup with depths, links to information about tides, moon and sun times and weather for the area plus links to any objects that are near the crosshair. Tapping again leaves the crosshair showing so you can drag the map to get a particular point under the crosshair and tap again to get information about it.

Requirements:
-------------
iPhone or iPad. GPS only required for real time route navigation. Optional Real time AIS, Tides and Weather information require an active internet connection.

Please note that continued use of GPS running in the background can dramatically decrease battery life.

NOT FOR NAVIGATION

This program is distributed in the hope that it will be useful. SeaNav should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction.
