You can get information about the Load Condition of any vessel directly on the Live Map by simply bringing out her InfoWindow.
Hover your mouse's index over the Load Condition Infotip to get more details about the most recent AIS-reported Draught of the subject vessel, the Max Draught that has ever been reported by her and the current Draught Ratio (which defines her Load Condition).
Thus, you can be actively informed about all the related details for any vessel that you may be interested in.
This piece of information is also visible in the Vessel Details page (included in the "Voyage Info" section along with other voyage-related details and options).
Note: The displayed information is based on the AIS-transmitted data that the vessels report.
