After completing this chapter, you should have a working sailboat where your BeagleBone Black can control the two servos to control the positions of the rudder and the sail. You should also be able to do this remotely at quite a distance using your XBee devices.

In the next chapter, you'll add a GPS device to your sailing platform. That way, you will not only know where you are but can also plan your bearing so that you can sail in an automated way to a new waypoint.
