I'd add that the boat in your picture is balanced aft. You can see that the back of the leeward hull is pushed deep and the tip of the bow is riding proud of the water. They are in no danger of a pitchpole. They could get knocked down by a puff, but a pitchpole generally happens when you are running downwind and really bury the leeward bow. Of course with large chop you can catch a tip at any angle. I'd second the motion to just hit the water and explore the boundaries of you and the boat. A few times in the water will greatly increase your comfort with the boat. Just bring someone who is not afraid to swim
