Foam backed vinyl is basically a temporary job as the foam disintegrates in 6 to 10 years..

I have done my Westery with the Hawhouse double sided closed foam and then vinyl.

easy and forgiving to fit and stll looking good..

The Foam Backed Vinyl always looks good when its in place ... easy to wipe clean ..... understandable why its used.

But when the foam fails and powders ... UGH !!!

When I was pulling down my FBV .. I had a vacuum cleaner running to draw all the dust and powder as much as possible ...

It's true it isn't the nicest of jobs, especially if it was stuck directly to GRP. I'm lucky that almost all of my vinyl is stuck to ply panelling, the whole boat is ply lined. Some panels detach easily and can be recovered out side. The window reveals have to be done in situ, but because the vinyl is all stuck in place there with PVA it wasn't too bad to get the mess cleaned up.

Typical life of the foam is 20 years, i don't think i'll be worrying about doing this again.

The lifetime of foam backed lining stuck directly to grp varies a lot depending on which bit of boat it's stuck to and where the boat is parked. The degradation is driven by UV shining through the grp, so stuff stuck directly to the underside of decks or the coachroof suffer more than that stuck to the hull, down towards the waterline. Sticking the lining first to plywood boards provides a screen pteventing the UV getting to the foam. If your boat is berthed in a nice sunny place, there will clearly be more UV exposure, particularly if you're lucky enough to have a berth in the Med or Carribean.

Hence the great variation in lifetimes quoted.

it all fails in the end though..
And then makes an awful mess.

The closed cell double sided sticky foam plus plain vinyl is just a better solution all round.

Used some of that on my last boat, then i switched to foam backed vinyl. I'll live with the 20yr lifespan, my boat is all ply lined and not in a particularly hot climate.

Take a boat with sticky backed foam to anywhere hot, like the Med and it peels off in short order.

Paul, horses for courses I suppose.
Can't see my boat ever getting that far 😪

Corribiee MK2 to be precise. She has been used and abused and I picked her up in a real state. She had been partially submerged due to a seacock being removed on a drying mooring ... and the tide came back in ... before it was replaced. Anyway, last year I did the stuff needed to get her seaworthy and fun to sail. I still have some stuff to do this spring (seacocks actually!) but thoughts are turning to what to do to the interior. She is stripped back to bare GRP and there is a light splash of unknown paint over it. It looks dirty and messy.

I was thinking about sanding and painting then started to wonder about other coverings, to make her more cosy. What would you do, and why?
Strip off any loose paint.. clean.. sugar soap.. repaint with dulux kitchen or bathroom paint (with the mould inhibitors)..

My Kormoran has that style finish and TBH - looks exactly 'lumpy paint'because the GRP is not finished off with nice smooth gel. It also has a lot of condensation with such ....

I will be van lining it ... that way I get a better cosmetic finish and no longer condensation dripping.

Thanks all, looks like time/budget might restrict me to a dab a fresh paint this year, but seriously considering the van lining for next years project.
