Knocker White

Has to be one of the Watkins tugs

Not Watkins but White's: W.E. White & Sons (Towage) Ltd., London. I'm nearly certain that this is KNOCKER WHITE, built in Holland in 1924 and now preserved.

Looks like Knocker White and as Bob says - now preserved.

Definitely KNOCKER WHITE, built as the CAIRNROCK in 1924 the London lighterage firm Harrisons. Think I remember her at Larne when they were building the Ballylumford tanker terminal in the sixties. Jim.

A steam tug with a Diesel engine is not very historic, sorry, even with the tall funnel.
