I have a large RC sailboat (a Victoria) that I am interested in making somewhat autonomous.

Looking at the tools and products available here it seems possible, and that some people have already gone far down this path.  However, I have not seen any sensors designed to measure the apparent wind angle on the boat.

Perhaps I am just not seeing the solution, but I can't see how to automate a sailboat without knowing what the apparent wind is.

If anyone has any experience or ideas in this area, I'd love to hear them.

Thanks,

PM
