It is important that anyone going to sea on a vessel understands the principles of vessel stability. The course material included here introduces the principles of vessel stability, the stability hazards that can make vessels unstable and the actions that need to be taken to keep a vessel stable and safe.

This is the old stability course and is not available to new users on the site. It is only being held open until the end of April 2017. The revised version of this course is above, Fishing vessel stability 2017. If you are going to undertake the final online stability assessment then we strongly advise that you complete the 2017 course to ensure you have covered the revised content.
