High winds precipitated a chain of events that sank this 37' sailboat. First, one of the boat's bow lines chaffed through there were no chafe guards' and the bow swung around and began bumping against a piling. The wind then blew much of the water out of the harbor, which caused the keel to become stuck in the mud and the stern to become wedged against a piling. When the displaced water returned, the stuck boat stayed put on the bottom.
