Windsurfing in challenging high wind conditions is not for the faint of heart. Windsurfers can achieve speeds that would be respectable for a well-powered speedboat. Nor is it particularly easy to film a windsurfer traveling at such high speeds with a drone. If anyone is up to the task though it's contributor RikDingo, who has created some of the world's best aerial views of windsurfing. In this video, he films a windsurfer hitting about 45 mph (just under 80 km/h), no easy task!
