The Tug M. DOUGHERTY  is mentioned numerous times by JW in his journals.  He normally writes that the Tug MIKE DOUGHTERY is at the Ways, mis-spelling the last name and referring to the full first name as MIKE.  The first mention is October 29, 1911. One of the many that followed was twelve years later on March 30, 1923 when the Tug goes in for a complete overhaul .  JW gives more details of this final visit on May 10, 1923.  Use the search engine on the Home Page to find all the entries and remember to spell the name as JW normally did.
