If you really want to know - What A Towboat is, or isn't .... Why not search "Old River Bill's R/C Towboats?"
you'll find it, and once there, just close your subject = real or replica and find out the vast differences between Tugs & Towboats!
They're both classed a workboats- Yes! .... But the similarities = End There!
True! ... They do build "Hybrid Towboats", which are called "Cajun Workboats" that do carry characteristics of both Tug & Towboat.
But these boats differ from vessels built further inland and north of Greeneville Miss, where they're boats are called = Delta Boats.
Above greeneville you will find the common term - towboat is used with most all - River Rats, as folks who work inland waters are called by steamboat traditions.
And Please! .... Never call a Tug, a towboat! ... Or a Towboat - A tug!! Because it's considered an insult to both vessels and their crews. "One more thing I might add here", this article on this website was likely written by a writer from a newspaper or magazine - I think. So check the facts yourself to see if I'm full of prunes, or tell'n the truth!
Education is a great thing, but doesn't or shouldn't allow mistakes to be made. But some sure abuse the rules and ethics and you need to check the facts - Yourself! So go ask a river rat about tows and river work boats ..... They'll Learn Ya = right!!!!
