The sails are 260 feet tall, they say they measured the winds at that height on previous crossings, maybe the winds up there give them some advantage, maybe a more direct route? Just guessing. Another thought is they can use the engine and the sails at the same time, possibly avoid long tacks but still getting fuel savings. I used to have a small sailboat with an inboard electric motor. You can do neat things with both available, the electric motor needs no warmup or startup and I could add a little push here or there if needed, or use both together.
