Ply thickness

[Brad Y]

It's 12mm ply for decks isn't it? For some reason I was thinking 9 but it seems a bit thin for my fat guts

[Hooked]

Yep 12mm mate.

[splashy]

Confirmed. 12mm.

Id use something thicker if u wanna span more than 300 x300

[Brad Y]

Its ok mate its got plenty of bracing and crossbeams running under it. Ive done full decks before but just couldnt remember what size I used.

If you want durability use King Starboard (BLA). I did my deck with it and I'll never have to do it again.

[Danmaso]

is that like a plastic board sort of product?
have been tryn to find something like that for a while....

[Mandurah Marine]

Yep. Marine Grade stabilised polymer. 4 grades available - original, XL (33%) lighter), Starlite XL (as light as XL, recycled), and anti skid.

Use normal woodworking tools. BLA can also cut to order if required as they have a CNC machine - they make under roof/gunwhale rod holders, storage lockers, galley drawers, engine room floors etc. I used the Starlite XL (12.7mm) on my main deck and have 400mm ribs - no flex. I also glued my carpet to it with normal contact cement. The boat lives in the water and did the job over a year ago and all is like the day I put it in.

What is a sheet of this worth???ld be interested in a refit of my tub to lose the extra 33% weight just for ease of getting the boat on and off the trailer at shallow ramps when it has little water under it.

That's a very cool looking product. Ryan when you say that the XL is 33% lighter is that lighter than the original King Starboard or is it 33% lighter than plywood? If it is lighter than the original Starboard then do you know how much lighter it is than plywood.

Cheers, Dror

Thanks Ratbags....hows the price though may stick with the heavier floor me thinks.

I knew I should have been a bit clearer! It is 33% lighter than the original KS. Have a look at the links Ratbags put in and it should give the weights. From memory the XL and Starlite XL was just slightly under plywood. But given that I have an open boat where my floor is 40mm above the hull, it rains, there is always water in it, that is why I went for it so the price is very easily justifiable considering how it will look in 10 years plus time.

eg 341206 Starlite XL 12.7mm x 2438mm x 1371mm retails at $284 (black only)
341106 XL same measurements $331 (white) - this is what I used (not the starlite XL as I previously posted).

Considering what I went through with my original marine ply deck (heaps of 2 pack sealer, sealing every cut, every hole both sides, dry time between coats etc etc) that lasted 18 months and it ended up costing close to as much after sealants etc, I wouldn't look back - The flex all boats have, the drying/failing of marine ply glues, layer separation (especially at cuts/joins) even after all the meticulous prep compared to "just cut and drill the booldy thing and forget about it" made my mind up. I also ended up using the off cuts for all sorts of things - like the shelves my dear bride needed on the house fridge. No cut, paint, wait, make - just cut, make, use.

If some people wanted to go this way I would recommend getting together to order a couple of sheets and get the price down. You never know if you don't ask.

Um yeah marine ply is $60 a sheet. I think I will stay with it!
