Thanks to a tip from a reader, I now know that Crounse has at least two new boats. The other is the Janis R. Brewer, which the U.S. Army Corps of Engineers last reported was in the Cannelton pool on the Ohio River. It's heading up the river, so if it gets this close I'll try to get a picture, although it's probably identical to the Linda Reed.
According to shipbuildinghistory.com, Crounse took delivery of the Janis R. Brewer on April 9 and of the Linda Reed on June 16.
The site also says a new 6,000-hp towboat known as the AEP Leader was due for delivery or was delivered to AEP in July. Another page shows that the AEP Leader is scheduled for delivery this month, and it says four other boats that AEP had ordered for delivery this year and next have been cancelled.
The Coast Guard PSIX database lists the AEP Leader as "in service."
I'll just keep watching the Corps site and see when various boats are supposed to be in my area.
