I tend to agree on the airbrake however it seems to be a feature of almost every new cat except the Voyage boats. The downside of sleek however is the Voyage boats shape between the hulls is almost like a aircraft wing. Lots of potential lift there and judging by the photos of the hurricane hole they got airborne more than the other boats. Still I loved sailing upwind in a Voyage 440. Don't love it near as much in a Moorings 4800 or Lagoon 450.
