I've not directly compared pressure, but knowing the owners of two boats in question, I doubt the pressure is much different. So this leads me to believe the one has sagged and the other hasn't. Why? good question.
Like I said. I've noticed a similar issue. I've been lucky enough to hang out with some folks that have been involved with R&D for Aire for a long time and I can say with certainty that their designs have changed significantly over the last few years especially. Newer designs have gained more shape by design. One of the problems as you put it is with the wireframes. When I compared a wireframe with a 2004 jaguarondi there was a significant difference. I don't know if the older wireframes are available upon request. I don't think they are sagging but last year I purchased my first new Aire so it will be interesting to watch over time. Good thing I took pics of the brand new boat.
With my previous boats, JPW, SOTAR, and Maravia I can get rid of my wrinkles if I inflate them to full pressure, especially after sitting in the heat all day, the problems is that I don't run my boats at full pressure or let them sit in the heat for long so it is something I'll have to deal with.
Thanks for the notes Elk. I simply love talking boats.
