Two things decide what you can do in Vessel Settings: whether the gear button appears at all, and whether the tabs you reach can be edited. Both are set in the Vessel Settings row of a crew member's permissions, which has a View and an Edit permission.
Opening the page
The gear button is shown only while a yacht is open, and only to users who hold Vessel Settings → View. Management Admins, Management Users and the Captain have it automatically. A crew member needs it granted in their permissions. Viewers and Management Viewers get every View permission automatically, so they can open the page, but they see it without any editing controls.
Owners never see the gear button. Owner access is granted feature by feature and does not go through yacht permissions at all.
Changing anything
Almost every editable control on the page needs Vessel Settings → Edit. Management Admins, Management Users and the Captain have it automatically, a crew member needs it granted, and Viewers and Management Viewers never have it. Without it you still see the tabs and their contents, but the add, edit, delete, import and save controls are hidden or disabled, and a department or rank's required documents window opens read-only.
This one permission covers the yacht particulars on General, the Crew sub-tabs (Ranks, Departments, Certificate Categories, Safe Manning and Work/Rest), Vessel Documents, Connectors, Inventory categories, and Finance (currency and budget categories).
On Vessel Documents, a crew member also sees only the document categories they are allowed to view, and can change a category's required documents only if they may edit that category's documents too.
Actions with a narrower rule
A few actions are restricted further, whatever your edit permission:
- Archiving the yacht: Management Admins only.
- Adjusting the licence on the Subscription tab: Management Admins only, and only while the yacht is active.
- Assigning form templates and controlled documents to the yacht on the Controlled Documents tab (Forms and Documents sub-tabs): Management Admins and Management Users only. A Management Viewer sees the Assigned? switches but cannot move them. On the Forms sub-tab, the Captain, crew and Viewers see the categories, but the full company list of templates is loaded only for Management roles.
- Adding, editing and deleting required action policies:
- For controlled document reading policies (Controlled Documents → Documents): Management Admins and Management Users with Vessel Settings → Edit.
- For form policies (Controlled Documents → Forms): Management Admins and Management Users (and the Captain at the API level, though browsing all templates on the Forms sub-tab is for Management roles).
- The Tasks switch: Management Admins, Management Users and the Captain. A crew member with Vessel Settings → Edit can flip it, but the change is rejected by the server.
- The Subscription tab: shown only to Management Admins, Management Users and Management Viewers on the web app, so the Captain, crew and Viewers never see it.
- The On-board app tab: shown only to System Admins.
When the yacht uses the on-board app
From the moment the on-board Nauticare app starts being installed on a yacht until it has been fully removed, the cloud still shows Vessel Settings but removes the controls it can no longer honour. The Connectors and Inventory tabs show a Managed on board notice and become read-only, and the Tasks tab disappears. Everything else, including the yacht particulars, crew settings, documents and forms, is still edited in the cloud.
