Ozone Submarine (M): A Harness That Shaves Off Drag for a Few Meters of Glide

The measurements are unsentimental. There was no difference at trim glide or over a distance of about 5km; only after flying another 5km above 53 km/h did a very faint advantage emerge. It's a difference an ordinary pilot would struggle to feel. But on the final glide of a competition, things change. Across several glides, the accumulated 5 and 10 meters are what separate one line on the scoreboard from the next. The Submarine is neither a comfortable harness nor a fast one. It's a tool with a sharply defined purpose, one whose tiny margin only turns into a real reward for the pilots fighting over the podium.
