TUG CONVERSION: AN ALTERNATIVE TO NEW CONSTRUCTION

Craft which were built in the latter days of World War II form the basis of most present day conversions, although many boats built in World War I also found their way into commercial service. There are many reasons to either convert a sound hull of some other type into a tug or to modernize and improve an older tug. The principal reasons are: (1) a sound hull of the desired size is either available at a reasonable price or already exists in the Owner's fleet; (2) the acquisition cost of a new boat exceeds the Owner's ability or desire to pay; (3) an otherwise suitable boat has obsolete machinery and equipment and/or inadequate quarters.
