The algorithm has become pretty complex and I use a visualization to simulate how the boat would behave at different locations on the ocean in different wind conditions. It helped me fix tons of small bugs which I couldn’t find by real testing. Here are some interesting points: The boat can’t sail straight upwind or…

This video shows how the sailwing is being controlled by the flap just like an airplane wing. https://www.youtube.com/watch?v=nSHC5fMZiU0 A powerful fan is blowing air onto the sailwing. When the autopilot sends a wireless command to the actuator that moves the flap, the sailwing starts moving until the flap points in the same direction as the…

In this video, the boat is sailing against the wind at 45 degrees. No matter which direction the wind is blowing, the boat will find its way to the destination. https://www.youtube.com/watch?v=_Wao6VeJTZ4

This aluminum support makes the boat easy to transport from my warehouse into the van and then directly into the water. Maybe I will use it for the official launch from Newfoundland, just need to find a suitable launch ramp for small boats.

The boat got wet for the first time and it went awesome! Although the wind wasn’t high enough to make thorough tests, the boat was moving through the waypoints. Below is a link to the tracking map from testing on a lake. http://track.opentransat.com/?lake2019 When you hover your mouse over any green dot, you will see…
