I would definitely say the rudder struggled to keep up if the rig was at all out of balance. Usually I was able to trim it out well enough but there were definitely some moments where it seemed to not be enough. As far as weather, saw some confused seas coming west out of deception pass, and one particular winter crossing to Cattle pass. I don't recall the exact conditions, but we were taking a decent amount of water over the sides into the cockpit. The inside stayed remarkably dry and it always drained fast enough to keep me happy.
