The vinyl/foam hull liner of my boat has disintegrated - the foam has turned to dust and the liner sagged off. I am scraping and cleaning it all up - a dirty and unpleasant job. I don't want to replace it with the same material - what is best way forward to make a long lasting liner?
 
5mm self adhesive closed cell foam from Hawke House. Better insulation, waterproof, doesn't seem to rot, easier to fit. Fitted to my Vivacity and lasted the whole 10 years I owned it like it was still new. Covered in Ivory (white!) leather effect vinyl it looked like a modern boat. Was pricey for that boat but worth every penny and stopped any condensation. I didn't do a perfect cleaning job either, just got the loose bits off.
 
We are using white vinyl to re-cover numerous head and side linings from C&J Marine. Quality product, easy to use and really pleased with the results.
 
If you have enough space - glue battens to the hull and fix 9mm T&G pine boards. Then paint or stain. You can add closed-cell foam sheeting between the battens to further improve the insulation.

I have the same problem and one of this winter's projects is to do the same work as you. Thankfully, it is just the forepeak and aft cabin as the saloon is lined in wood panels.

I will follow the suggestions with interest. My current thoughts are to remove the vinyl clean it and the hull they use a closed cell foam material and cover with the original vinyl.
