I have a suggestion on your postings that may clear up some confusion.
You state the location and date as "Mississippi, then the date"
Could you add "River" to Mississippi? There may be some confusion in people thinking the photos might have been taken in the State of Mississippi, not the River.
Just a thought.

Some times a customer wants a boat with a certain amount of horsepower to operate on a waterway that has a restricted draft. Some of these former Cenac boats go to oil gathering stations in the Louisiana bayous that are situated on man made canals. The three engine layout permits a wider boat to have less draft than a conventional twin screw towboat with the same power.

Powered by three Cummins KTA19-M2 diesels, total 1,650 hp.
