Thread: Light Weight Ply

As I've answered this question on another forum, I'll just touch the important stuff. Goldcore isn't well suited for small craft construction as it has crappy stiffness and poor shock load properties. It's a cabinet substrate, not planking material.

I notice that in the website , they only specify for internal cabinetry , not for exterior hull fabrication.

I would follow P.A.R.S's recommendations, check AUSSIE PLYWOOD thread .

Yes I will be sticking with the Joubert Gaboon I think ! Maybe some hoop for the load carrying areas and the gold for any appropriate interior fit out.
Thing about most Crowther designs is very little of the material is superfluous to the structure so maybe only gets used in bunk lids etc.

Why did you chose gaboon ?

Does it need pre treatment against rot ?
If so what did you use or did you just epoxy coat and paint ?

I bought 9mm meranti ply sheet to do some plywood repairs in cockpit on wooden trailer sailer. As it has good rot resistence. It was supposed weigh 14.8 kg per sheet and have 7 layers, so fitted my need.


but when i got it home i found it weighed 21.2 kg and was only 5 layers ... They couldnt explain why and had no alternative accept for gaboon . I swapped it for gaboon which weighed 13.7kg for the sheet

I suddenly had thoughts about its rot resistence but cant find much about it , thou seems its not as good as meranti.

Dude, this thread's 12 years old and at least one of the respondents has passed away.

The only lightweight ply that i have dealt with was balsa ply. Doubt it would suit boats. It was used for a sculped bar -covered in fibreglass then 2 pac.
