25-30 is the normal life expectancy of a RoPax vessel. As the ship gets older she naturally becomes more expensive to run and maintain. Inspections /audits and surveys also increase, this is the natural life of a ship. Approaching 30 and still in daily use is good for a ferry.
Another issue with shipping is that unlike trains, aircraft & land vehicles ships are very unique, even some sister ships are built differently. Each new generation or design has bugs of its own which take time to work out. Materials change widely as does the quality or workmanship. One issue with tendering is that one shipyards practices may not be as good as the next so you could have a wide variety is the quality of new ships. Loch Seaforth was built by a German yard with a good reputation for quality, Bute & Argyle were built by a Polish yard which isn't as widely respected, only time will tell to be honest.
Just look at the difference in build quality and general ship handling between Clansman and Hebrides. Hebrides is a much better seaboat. I remember reading an article in Clyde Steamers about Captain McCrindle's differing experiences when handling them both, he said that because of the way the bridge wing ergonomics are set up on Clansman, he didn't have anywhere near the confidence of berthing her in difficult conditions compared to Hebrides, which was layed out more traditionally where the master is able to stand and use the controls facing in a forward direction, rather than sideways!
