Your fast bottom has nothing to do with being busy at anchor. It's hull =
configuration and displacement that makes you squirm about at anchor. =

To be honest, we only had the problem on one short, but windy night at anchor.
The boat was sailing at anchor, practically tacking back and forth. She never
did it again, so it may have been a unique combo of wind and current.
