I have been on lots of ferries quite often, sometimes commuting on them daily for work in all kinds of weather conditions. Sometimes the ride is glassy smooth, other times the spray is soaking on the cars and the ride is very rough.
The rule is you are supposed to turn off your car alarm but many times drivers forget that and go up to the top deck with them left on. Or they are out of area tourist who are so busy yacking and excited that they don't bother to read signs. Then when a strong wave hits the car alarms start blaring. That can be very annoying if you were using the crossing for an opportunity to take a nap. There are times when the tide has been so low or high that the loading ramp is at a very steep angle. Other times I have had to wait because it was too low of a tide for them to deploy the ramp.
Sometimes the pilots hit the dock way too hard, that is quite the experience.
I have been on a ferry that stopped right in the middle of a crossing because someone decided to jump off the boat to commit suicide.
Or for more pleasant slowdowns to allow a pod of killer whales to pass by.
The longest ferry ride I have taken was from Homer Alaska to Kodiak Island Alaska. The only time I have felt slightly seasick was on that trip.
Anacortes, WA thru the San Juan Islands up to Vancouver Island British Columbia is a beautiful experience and a fairly long ride as well.
I have been on the Port Aransas ferry but I was a kid at the time. I have crossed the Mississippi river on various ferries and the Columbia river on various ferries. Also the Balboa Island Ferry in California.
I have been on walk-on passenger only ferries including one that was a jet foil going from Seattle to Victoria British Columbia as well as the bigger ferry on that run that cars could drive onto.
I have been inside a Boeing 929 Jet Foil Ferry but only while it was still in the factory being built. It was in the same building where I was working as an assembly mechanic on the 727 and 737 jets but I never did any assembly work on the ferry, I just liked to go in and walk around once in a while.
So a great many ferry rides over the years and no doubt more to come.
