Neptune C-Map Planner
This passage planning and online navigation program offers you the MAX C-Map cartography providing accuracy, detail, world wide coverage, as well as all the Neptune course calculations and tidal data. The C-Map charts can be installed directly onto your PC.

program performs course to steer, course over ground and optimised departure calculations, displaying tidal streams, and reference port tides, also the program interface to GPS and AIS.

After a calculation the results are readily available on screen and takes into account the effects of tides using the inbuilt tidal data.

If you are interested in the effects of wind
weather reports and forecasts on to your PC.  The weather forecasts interfaces the wind details to Neptune C-Map Plotter Planner with the option of using the forecast and Neptune tidal data to produce Course Calculations.

The routes can be edited on screen and will show your the no sail areas. For those interested in boat performance then Polar Plots and boat speed estimation routines for the wind conditions are built into the software.  The program's output is easily copied to the clipboard for pasting into a passage plan for SOLAS purposes.

Connected to a GPS the program will act as a plotter and at the same time allow you some very flexible waypoint management between PC and GPS.  If you do not connect a GPS to the PC you can plot in manual mode.  Waypoint files can be created either by typing in the co-ordinates and names or by simply pointing and clicking with your mouse, you can keep and edit many waypoint files on your PC and call them up at the click of a mouse. Once a leg has been set-up you can use the tide roll function to see the effects of different departure times on the course to steer and the effects of course over ground.

AIS formatted to allow target's predicted course to be viewed taking into account tides, track plot, configure target static data to appear on screen, record data and replay log files.

You can plan into the future or re-visit last years calculations as you wish.  There are many additional features that can be explored. This program is not time limited, and so no yearly updates are required, however the C-Map chart updates are annually available.

For generalised route planning the system can be used without purchase of additional charts; however for detailed navigation purposes additional charts are necessary. The demonstration area is the Central English Channel and adjacent coast of France. Worldwide coverage is available from the C-Map Chart Selector CD.

Neptune C-Map Planner is an easy to use programs, full of great features, calculations and a pleasure to use.
