[Knot On Call]

Can anyone provide help on changing out the upper salon (helm area) headliner in my 2004 52 sovran salon.  The headliner is drooping like a parachute. I understand that many boats of this model have similar problems particularly if in hot environments. I saw another 2006 model with the same issue. The boat was a Florida boat most of its life. The headliner is made of Whisper Wall mounted in a track system. The perimeter edges though are only stapled to a furring strip which is odd. Tiara could not offer any help. I can't seem to find anyone including Tiara dealers in the mid or upper Chesapeake Bay that feel comfortable tackling this repair. Has anyone DIY or had the headliner changed out?  Any suggestions would be appreciated. I'm fairly certain that the headliner is not foam backed in the upper salon. It the headliner supposed to look like this or is it to be tight and flat as the interior headliner? I would think tight and flat as there are indirect string lights installed behind the perimeter molding  as in the interior.  Any help or suggestions would be appreciated.  This was a #1 to address when we purchased the boat last Spring.  The boat rides beautifully. Looking forward to some NE coastal cruising next year. MIke
