I just bought my C34, hull number 1312, and noticed the same thing. Also, water collects in the channels on each side of the companion way door. Seems as though there is a design flaw or manufacturing flaw with the balance of the decks. Even with a full aft water tank, it does not help. However, if I stand on the boat near the wheel when first boarding, the water in the channels will drain. I always need to warn others not to stand too close to the door, unless I want them to get wet.
