Saved ships are stored on this computer (browser local storage) and reloaded automatically next time you open the app — no need to re-enter particulars every session. Use "Delete Selected" to remove a saved ship. These particulars are used across all Annex tabs — especially Annex VI (NOx Tier III / SOx applicability by keel-laid date) and Annex IV (passenger-ship sewage rules).
