Mapping:
World wide planning chart, for a zooming-range of more than 250 nautical miles.
World wide shorelines database, which can be displayed with a zooming-range between 0.25 and 250 nautical miles.
Scanned Mercator Projection charts. Scan your own charts!
Fill your own object database (light houses, ports, mountains, signals, etc.).
Import and export capabilities to exchange scanned charts and objects with other users.
Nav_Data window with navigational numeric data updated every second: local and GMT date and time, estimated or GPS position, compass and true course, ground and over water speed, bearing and distance to next way point, etc. One single button starts the Man Overboard procedure which opens a window showing the man and the vessel, distance, bearing and elapsed time.

Dead reckoning and piloting
If a GPS is not connected, navigation is done by dead reckoning, and in addition, by using leeway and current data maintained in the logbook. Fixes can be done by analysing the amount of saved miles by using bearings to different targets, by analysing bearings at different moments to the same target, by processing the distance from high objects beyond the horizon, by analysing celestial sights or meridian transit, or by copying the position from an unconnected GPS to the logbook.

Celestial navigation.
Fix with 2 to 4 sights or upper meridian transit. Latitude with Polaris is supported as well. The nautical almanac is automatically kept up to date by EASYNAV. Calculated data can be overwritten with the one stored in other almanacs, if based on the users requirements.
A bodies finder gives GHA or SHA, declination, parallax and semi-diameter of bodies at any time as well as altitude, azimuth, GHA Aries and Moon phases. It also allows the user to print his own Nautical Almanac for the desired period.

Waypoint lists
Create as many WPL as required, each with up to 499 way points. The user may switch to the desired WPL during navigation at any time.
Create a Great Circle route divided into the desired number of way points entering departure and destination only. Select your GOTO way point: the plotter will give you date and time of arrival and VMG to it.
A WPL may be filled manually, by using objects stored in the data base or by clicking on the mouse-button on the plotter.

Tide calculator.
You enter tidal data for low, high and next low tide for principal and subsidiary ports to obtain a grid with a row for each 5 minutes of tidal time with height of water, speed of current and course to steer and speed over ground.
Moon phases may be determined by using the EAYSNAV Nautical Almanac.

GPS
Any GPS (or other navigation system) with NMEA 0183 output capabilities may be connected through a serial (COM) or USB port. When GPS is active, EASYNAV stops reading data from the logbook used to calculate the estimated position, using GPS latitude and longitude data. Ground track and speed are then calculated by using successive GPS positions. If GPS fails, last position, speed and course are written to the logbook and the system continues navigating using the EASYNAV calculation.
A GPS Reader is also supplied to monitor GPS output data in order to solve problems if any issues should occur.

Nautical Dictionary
A 5 languages dictionary is supplied with over 500 terms. The user may edit the dictionary to modify or add terms to it. An empty column allows the maintenance of terms in a sixth language.
