This site is superb, when looking out from our lofty perch over the Severn estuary my son often asks ' Where's that ship going to Dad??' I can know tell him by loggin g in and selectingBristol and Solent and then clicking the map section of Severn estuary.
Superb!!! I cant thank you enough.
(We've just got to get one for planes now they're about low enough to make out which airline but their destinations remain a mystery)
