Congrats on your Ranger 30
I also have a Ranger 30 and it is a great boat. Much different than other Rangers (different designer).If you would like a copy of the original brochure, just let me know where to email it.The headliner was professionally replaced on my boat before I purchased it and it looks like new. However, I have messed with other headliners in other boats (including another Ranger 30). I am not sure exactly what you wish to do. But if it is in pretty good condition, but sagging some, be careful that you do not destroy it trying to fix it. I can take a closer look at what I have and maybe can add some thoughts on how to deal with it.I'd be happy to share my R 30 experiences with you, if you'd like.
