Capcode Software suite for sailor Capcode is a tool, written in java, so basically portable on many operating system (linux, windows, and soon mac-os) that provides assistance to the sailor, and in particular the sailor practicing regatta. Connected to the on-board navigation system via RS232 serial link, it read the NMEA 183 messages and presents them to the user under several formats (position of the boat on a chart, repeaters, etc).

Presentation
Capcode started as a personnal need for something capable of acquiring the polar of speeds of an old Jeanneau Sangria: Balthazar.
the chart display at that time was limited to the capability to display the area where we are sailing: basically to have a jpeg, geo-referenced by a xml file.
As time passed and the need geeting more and more precise, we decided to provide the tool as an open source project.
Today, capcode is still not mature but starts to have interesting features that go beyond our original needs.

What does capcode?
acquire
and decode the NMEA sentence from your boat instrumentation and GPS
Every boat may have different configuration of NMEA message, depending on the kind of instrument you have on board. For example, if you have a wind sensor and you speedometer is out of order, you can cheat and take the surface speed from the GPS. Note that in that case, the current will be ignored.
compute
1) the true wind direction and force, from the boat surface speed and the relative wind sensors,
2) the target speed, if the boat polar is known and selected
3) the geographic wind (if you have a true heading sensor)
display
1) several repeaters show acquired and computed information like: relative wind force and direction, true wind force and direction, best vmg, boat speed and log, the polar of speeds for the present wind.
2) Charts are displayed today in two format: first is the classical .kap raster format and the second is a buit-in format known as ccmap (consisting in a pair of file: one picture jpg, gif, or png and one xlm file giving georeferences data.
3) on the map are also displayed the trace of the boat, the route followed (with its waypoints), and some speed vectors (like where will be the boat in 5 min)
4) the polar of the speed can be projected directly on the map, showing immediatly the best option to reach a point upwind or downwind
What capcode does not?
And will probably never...
IT WILL NEVER BE A CERTIFIED NAVIGATION SOFTWARE
IT WILL NEVER REPLACE YOUR TRADITIONAL NAVIGATION MEANS
for the rest, anyone can create his own plugin (and share it)
