Tugboats are the hardest working vessels in the shipping business, safely guiding freighters several times their weight and size to dock and back out to sea. This all-color salute to everyone's favorite little ship examines "tugs" today at ports around the world. In addition to depicting tugboats at work, the book explains the various tasks with which the boats are charged, the work of their crews, and the engines and designs that allow these relatively small vessels to tow incredible tonnage. The author also explains how older tugboats are overhauled for continued service and how manufacturers are finding new markets by revamping decommissioned tugboats-and even building brand new ones-for use as private cruisers. In addition to being a NASCAR journalist and the author of three previous MBI books on the subject-Behind the Scenes of NASCAR Racing, Stock Car Race Fan's Reference Guide and NASCAR Transporters-Bill Burt is a longtime tugboat fan just now getting the opportunity to indulge his passion in book form.
