The world-famous Sir David Attenborough ship was spotted sailing under the Forth Rail Bridge.
Crowds gathered to watch the vessel on its way out of the Forth, having undergone a multi-million pound refitting at Rosyth Dockyard. It arrived in the UK in June after a seven-month mission in Antarctica, reports the Daily Record.
Now, it is moving on to Essex after carrying out scientific trials on the Scottish coast. Robin Cook, 69, from Inverkeithing in Fife, was part of the crowd that gathered to take pictures of the boat in North Queensferry.
