Looking at how the boat sits on her "lines" in the marina or flat water will tell you alot about how you have her balanced, fore and aft. My boat has a fine groove in the gel-coat at the boot strip that appears to be the factory calibration of how she should float, and the boot is laid to that groove. Therefore the boot stripe tells me how she is balanced. In most conditions I need 175' of chain forward to get good light to mid range wind conditions. But when she's got a bone in her teeth, jib powered up and bow down, I don't like seeing green water over the bow. Make sure your locker drains are getting the job done.
