"@James Pike It's a prototype just to test the concept. The ocean-going boat will look much like the CAD model you see in the first picture (or the picture below) with some improvements. It has all the properties you suggested.
"@Tobias Power is the main concern. The wingsail "flap" will be adjusted once per hour and the rudder will correct the heading every 5-10 seconds and even this would drain the batteries in 4-5 cloudy days."
"@Evgeni Trenev The mast will be made from a thick carbon fiber tube. Both the mast and the keel will be connected to inner structure made from aluminum. I am not sure I can use ropes when the wing is free-rotating.
You can see the keel with weight…"
One year has passed since I launched the autonomous boat OpenTransat that has attempted to cross the Atlantic Ocean and I wrote an article about it. The boat is lost in the ocean after being hit by crazy storms, but I didn't give up. Currently, I am…
"@Global InnovatorI still believe it wasn't the outer structure that failed. As seen in the comments in the tracking map, the software had some issues and the hardware watchdog timer was trying to reset the boat every three minutes with no success.…"
Good point, I will try to optimize the sailwing for both thrust and robustness. There must be some specific curvature that is most effective.
Yes, the solar panel is partially shaded, but from what we see on the…"
I was testing this boat on a lake, but I am going to test my next boat in my favorite place - Canary Islands. That's where I started a part of the development. The conditions there are very close to the real ocean conditions - high winds and…"
"@Gary McCray Now I understand, it's like a water scooter.
The sailwing will have an inner structure like an airplane wing. The mast will be made from a thick carbon fiber tube.
Regarding the color, yes, it is one of the recommendations on the…"
The boat will reach the shore one day, but it can take a very long time. There is a contact information on several visible places on the boat. Yes, there were crazy storms before the boat stopped transmitting. Not sure if it has something to do…"
"Over the last years, I have been closely watching several attempts of crossing the ocean using solar power and thrusters. They had one common problem - the thrusters got jammed with seaweed or fishing lines. This is why I focused on a sailboat.…"
Over the last few months, I have been busy building a fully autonomous sailboat that attempted to cross the Atlantic Ocean.It was initially launched from Newfoundland heading towards Ireland. Although the initial attempt was not successful, I've…
