It has recently come to our attention that there is a bug in some stability criteria when using water on deck. This affects only criteria which group together multiple individual criteria. The problem has existed since water on deck analysis was introduced several years ago. The affected criteria are those derived from the parent criteria shown below. The caused the uncorrected (not water on deck) GZ curve to be used for evaluating these criteria, generally overestimating the stability of the vessel. The problem has been fixed in MAXSURF 23.02 which will be available for download within the next few days on softwaredownloads.bentley.com.
Further details of changes in MAXSURF 23.02 may be found in the release note.
