We’ve having a tug today, courtesy of regular bloggee Thirdwigg and this neat all-mechanical harbour tug boat. Rarely built in Technic form, Thirdwigg’s ship features ‘HOG’ steering and twin winch control via the cogs atop the pilot-house, and he’s released free building instructions too. Give your self a tug at both Flickr and Eurobricks, where full details and the instructional link can be found.
