Stuck?

A really busy day and a lousy weather day meant I was limited in blip ops.

Whilst walking the dog tonight I spotted this fishing vessel listing to port and running backwards and forwards in the same spot, not sure if they'd snagged something on the sea bed, but after about a hour they suddenly sailed round to the fishing boat berths.

Not sure which vessel this is as usual Peterhead's AIS is not working again.
