29. Hourly tow operating costs may range from about $25.00, for a
low-horsepower boat pushing one small barge, to over $500,_for
a large boat pushing a number of large expensive barges (e.g.,
liquid sulfur barges). These cost figures are based on Corps
of Engineers data which are priviledged. Therefore, more specific
information on tow operating costs cannot be given here.
The figure of $100 used in the text is, of course, only for illustrative
purposes.
