Adafruit Forum user Autonomous_Sailboat (James on YouTube) describes development (design, construction, programming and testing) of an autonomous sailboat that incorporates GPS and electronic compass sensors for navigation. Navigation decisions and control were performed by an Adafruit Metro M4 microcontroller. The software code is original programming in the CircuitPython language.
Successful field testing for a 0.41 mile one-way course navigation event is described in the video as well as a Google Earth-based trace of the route completed.
Well, here is a YouTube video of a model-sized “special purpose” autonomous sailboat that I have been working on for the past year or so (before that I made an model-sized autonomous motorboat and prior to that I made a model-sized autonomous model car). The video is a slideshow that describes the design, construction, programming and testing of the sailboat and has some videos showing how it navigates in the water.
Many thanks go to the Adafruit Forum moderators that provided valuable information which made this effort possible.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
