Inside Foam Hull Liner

[Johnlucia]

Most of the inside hull surface of our 1979 424 is lined with a thin layer of foam insulation coated with a kind of rough brown vinyl-like surface. I’m assuming it’s original equipment.

Anyone else out there have that? And have you come up with a reasonably efficient way to remove it?

My first attempt to remove a small section of it involved a lot of scraping and sanding and way more time than seemed like should be necessary.

Our 1980 424 had the same material.  Our solution was to leave it in place and cover it with a carpeting made for boats.  I don’t remember the manufacturer, but the carpeting is mildew and water resistant.  I chose a neutral beige color, which looks great with teak.  Using contact cement applied with a paint brush, installation was easy.  Cutting sections to fit wasn’t very hard.  They can be cut generally close with final trim done with a razor knife.  We’ve had no problems after 9 years in Hawai’i and the finished look is great.
