Another view of Aquitania Aground

Vessel (tug?) bottom left with two funnels, any ideas?

Would suggest she's an Admiralty tug from Portsmouth - Resolve class?
Photo of one here: http://www.shipsnostalgia.com/gallery/showphoto.php/photo/302410/title/navy-tug/cat/535

Tug/tender on right is Red Funnel's "Calshot" (1930, 684grt)
