Headlining plywood

[MM5AHO]

What type and thickness of plywood is suitable for headlining?
Thinking to put some in fwd berths area, without vinyl lining. Just ply sections screwed in place, and varnished.

Any suggestions?

6m/m

Melomine plasic sheeting is easy to cut and clue, also easy to clean and provides more reflected light.

Carpet tiles are also easy to install and you don't have a problem with condensate dripping on you.

Good luck and fair winds.

6mm is commonly used.

Hawke house I notice also supply 4mm.

Mine is thinner than 6mm, probably 4mm, but its only a small boat so the panels are not large.

I used 4mm ply on my camper and it was fine.

I've just today brought home from the boat one of my vinyl covered deckhead sections that needs either recovering or replacing with plywood. All the panels in the boat are starting to have the vinyl sag and droop.
I have quite a few, perhaps a dozen, sheets of 9mm, 8x4 sheets of plywood that are left from an unfinished and abandoned project. I am going to use the panel from the boat as a template to make a replacement panel from a 9mm sheet.
If it fits in OK and looks alright when varnished up I'll replace the rest of the boat's panels. If it doesn't work, I'll have to bite the bullet and recover the original ones with new foam backed vinyl.
I realise that the replacement plywood will weigh quite a bit but I was brought up to believe that I "should waste nowt and want for nowt."

If you do end up recovering the original panels use a water proof PVA glue. It's water based so no hazardous fumes to worry about and it's easier to use than a solvent based contact glue ... I did mine on the lounge floor.

9mm ply might be difficult if there's much curve in the roof panels

If you have any curve at all 4mm is quite adequate on anything up to a 40 footer, and as Vic said PVA glue is the stuff to use.

We replaced our roof lining with B&Q tongue and groove cladding. Has dulled to a nice 'piney' look over the years and is easy to do with brass screws etc. Also easy to get to bits of the ceiling for wiring if you need it.

Worked for us.

We used a Satin version of Altro Whiterock when we replaced all the headling in our Victory 40 ketch. It is uPVC so rot proof and easy to clean. Cutting and bending was easy.

It was expensive but we are very pleased with the end result.

I would say 9mm is too heavy and thick. A little flex is useful as boat is not square. 9mm may not flex enough. We have used 6 mm on this boat and the last one we used 4mm. Panels were very large on this boat so 6mm was more suitable (8ftx4ft)

Does anyone know if waterproof PVA glue is tolerant of high temperature? We replaced the headlinings in our previous boat using a non heat tolerant adhesive, When we went to the Med, the headling attached directly to the deckheads (ie not onto ply) fell off, so I don't want a repeat of this.......Also, I understand that this PVA glue works headling to ply - would it work headling to GRP?

 

[PCUK]

A superb low cost covering is vinyl flooring. Hard wearing (of course), easy to cut and glue and will last forever as you won't be walking on it. Vinyl flooring adhesive glue is also great for most other things being water based.

Here are the answers I got when I raised this question recently.

Did same in forepeak on last boat, 4mm ply in two sections with carpet glued on & a batten down the middle & a section around the opening hatch...
