Buoyfields have some similar properties to vessel tracks when placed on the Tote.
Once a buoyfield is made a Primary or Secondary track, a highlight is drawn around the buoy at or immediately after the current time. Additionally, if the buoyfield is designated as a secondary track the Tote continuously displays it's range and bearing from the current location on the primary track.
Since buoyfields are essentially handled in the same way as Tracks, the full functionality of the Track & Time Toolbox (accessed from the Tote) are available, so graphic plots can be produced and calculated data copied to the clipboard using Buoy data.
