In July 2019 we raced in Transpac - a race from Los Angeles, California to Honolulu, Hawaii. This compilation of video was shot out on the Pacific Ocean, most of it 1000 miles from land during our half-way party. As can be seen in the video, we launched and retried the Mavic Air from the boat while racing along at 15 kts (27 km/hr). The boat (Hamachi) finished first overall out of a fleet of 90 boats.
Launch and especially retrieval is challenging. The wind is blowing 20kts (35km/hr) but the relative speed across the deck of the boat is much lower. To perform the maneuver you need to turn off all of the collision avoidance / safety controls - everything is hand flown with high risk / reward.
