On the A-cat, it's faster to go on the wire first and hold it down for acceleration in the puffs versus sitting in, flying the hull, and pinching up.
Not talking about puffs, it is faster to keep one hull out of the water but still keep it flat, just kiss the top of the waves. On all cats I sailed so far I could feel the slow down if the hull flies high upwind. In light winds it helps to make the trap short and crouch. Ones the boat picks speed and want to fly the hull, you can stretch and translate the power in even more speed instead of heal.
