My Cal 28 ('86) is listing to Starboard when at dock. The scum line is about 1 1/4" higher on the bootstripe on starboard than on port side. Also getting some barnacles attatching on the space between boot stripe and bottom paint. I've measured from the gunwall to the bottom paint line...same both sides.... measured from gunwall to bottom of full shoal keel ( to see if it's off center) but exactly centered. 2 Batteries are just off-center of boat, bilateral 20 gal holding tanks, head holding tank (most of time 1/2 empty) is on the Port side. No water damage or water in the glass. So it seems equally loaded. Short of stripping off the paint and repainting the boot strip in the "right " place, what do you think is making me list . Of course, when sailing, this in not an issue. Thanks, Steph
