Hello James. I did some digging around in old notes regarding Amel production during that time. The previous vinyl with the polyurethane foam was trade named Skai and still has a presence in the marine market according to a quick internet search. Perhaps they now make a marine vinyl with felt/cotton backing as the safety rules governing using polyurethane have changed over the years. If they have a suitable material, I’m sure the distributor could recommend an adhesive.

Sorry to say I could find no mention of the replacement material. I seem to recall someone at the shipyard in La Rochelle mentioning that it was Naugahyde, but that term gets used a lot generically and not always describing the exact brand of Naugahyde. I have used Naugahyde for other projects and it could be a good replacement if you can find a color-texture match. They were pretty strict when it comes to what adhesives to use and they only recommend their own branded adhesives.

During my digging, I found that quite possibly some boats from the 1995 production year may have used the new overhead as the exact break was loosely described as around 1996 production which means September 1995 forward. They still had some of the old headliner when the new arrived so….

Perhaps Olivier might know but beyond that, I’m out of luck.

Sorry not to be more helpful. Joel
