How much hull flex or distortion is acceptable ? The door in the forward bulkhead binds slightly more once the boat is in the water vs. in the cradle and also you can hear it working when in a sea way. The same holds true for the bulk head aft of the navigation station which is part of the head enclosure and is most evident in a beam sea. I don't see any gaps but can make the floor squeak at this latter bulkhead by stepping on it. Thanks for any reply
