Had a fascinating couple of hours afloat at the Port of Felixstowe yesterday (Saturday) filming the tugs work with new arrival and first caller UASC Ain Snan, 141,077 GT, and built in 2012.
Its the first time I've ever been privileged to film aboard a modern tug, although I've filmed aboard 2 or 3 older/historic tugs over the past few years - a very different experience.
As usual, there's a film of the experience on this site's video pages - on the second page now, I think, search for "Ain Snan".
