The difference between Admin View and Masters View is the information available to the user. Masters view - has been designed to simplify things for the Master, only showing one vessel at a time.
Admin view - provides a complete overview showing the settings, reports, and full fleet view.

To change views:
Change from Admin to Masters view by clicking on the logged in users name, found at the top right corner of the page. (As above)
Next, under Vessel View, select a vessel from the list. This will open up the logbook for the vessel you have chosen (refer to the Masters view above).
Note: Selecting All Vessels in Vessel View will default back to the Admin view.
