07 310 sundancer cieling sag

Unfortunately, your problem may be that the skylight could be leaking. The ceiling is sagging because the glue is not sticking anymore and it’s wet. Have you noticed if it is more humid in the cabin?

Take the ring off the skylight and see if the fabric is wet. You’ll have to remove and rebed the skylight, if it is. Get it dry between the fabric and underside of the deck. Make sure there’s no delamination of the deck. Reseal the wood edges, rebed the skylight and re-glue the fabric to the deck.

 

Glad that there’s no moisture. At 15 years old, it’s a possibility. I had the start of a leak in the forward hatch in my 370DA when it was about that age. That’s why I know what fixed my sagging liner.

 

Lets get a little more info. What exactly is sagging? Is it the foam back vinyl that may have been glued on or is it a headliner board. In my 340SDA there is a plywood board that the headliner is attached to that board is mounted to boat.

If just the vinyl is sagging then the only thing you could do is pull it down and re-glue it. Depending on how it pulls down it may not be pretty.

If this is a board falling then you are going to have to peek under where it sagging to see if a mount may have come loose. You may also want to contact Sea Ray to see if they can tell you how and where the board was attached. I have seen on some boats that multiple "christmas tree" connectors where used.
