That is the MV Cahaba. I have been aboard that boat, several years after the incident.
W&G sold the Cahaba to Madison Coal Co. and it was renamed Capt. Ed Harris. It is still working as of a year or so ago, and you can still see the damage to the wheelhouse . . . < ouch! >
By the way, the Mauvilla was the towboat that picked up the Cahaba's tow and carried it on to Mobile.
