Let's dig in the reasons why the Reverso Air stands out regarding boat stability
The Reverso's shape is showing a very flat surface underwater with a forward V-shape.
Usually, on a more old school dinghy like a laser or 420, the shape is rounded. This has some advantages in reducing the wetted surface, especially upwind, but we made a different decision due to our experience : the flat bottomed shape allows an unrivaled static stability while providing better control at high speeds.
The chine is the sharp angle shape on the side of the hull. While this was common on plywood boats, you'll find it on very modern yachts. On the Reverso, the chine contributes to stability performance, especially when the speed increases, the boat feels to be "on a rail", proividing very accurate and stable ride.
Super large width makes things easier, especially during Gybes and tacks, when the boom never hits the water. It also helps a lot for bigger guys that feel a bit cramped on narrower yachts.
