Most likely not skip, since Coast Guard Sectors have multiple radio sites to be cover the large areas.

When I lived in Pittsburgh PA, the Coast Guard base at Owensboro Kentucky came in like it was down the street. I think they have repeaters the length of the Mississippi so you were not hearing skip.

But I am 200 miles from the Mississippi River. .jerry
Maybe you had some enhanced VHF propagation that day.
The sites for the Coast Guard's Rescue 21 Radio System are located are some very high sites or towers. In my local Sector the range from just 200' to over 600' and that a large range on VHF.

DSC DISTRESS
MF & HF Channel Information
Some of them are on the FCC rule links at the bottom of Marine VHF Channels - The RadioReference Wiki
Some companies have their own frequencies you would have to search the FCC database in states along the river to find them.
The USCG has radio sites indeed along the entire Mississippi River, and up along some of its tributaries, many of which are shared with the USA-COE. There are also beacons at every bridge crossing, dam, and lock on the Big Muddy. You often in Spring, and Fall, and before strong storm fronts get some pretty good VHF High Tropo Ducting down there in the South. It is quite normal to get VHF High Ducting openings of 100 to 200 miles for short periods. In times of very big Troposhperic Ducting, you can get widows for VHF High up to 500 or more miles, VHF Low up to 3000 miles, UHF 200/300 miles, and 700/800/900 MHz 100/200 miles. I have personally monitored California Highway Patrol from Charleston, SC on VHF Low, St. Bernard Parish back when they were on UHF from Jackson, and McComb MS, and FD's/PD's on VHF high from as far as 5 states away when I lived in Union Church, MS.
