Hi Raii -new Swiss Unmanned Hydrofoil Cat Under Development

[Doug Lord]

Pretty interesting-designed for unmanned sailing and especially considering the lack of wands:

Navigation
"The boat has to be for unmanned sailing. The steering is provided by an internal data processor, which is sailing autonomously, determining the ideal course, for example between two points, and depending on the wind conditions and the possible angle of attack of the sails. When manoeuvring, the course shall be dictated by an external data processor."
