One more thing to point out...
For me and my experience, this is usually a good indication that things are going to get nasty very soon. The dreaded calm before the storm, those with meteorologist experience can probably explain why, but I think it's because the two systems are colliding and the stronger one prevails.
During the collision there is dead calm, which to me means, get everything ready because the stuff is about to hit the fan.
I would think that after this you would find a new respect for your boat, often times the boats bail us out instead of the other way around. Keep sailing and listen to your boat. The C22 will teach you a lot.
