The best quality okoume (Gaboon) plywood available as far as I'm concerned is from Andrew Denman Marine in Tasmania. I have several sheets here, with one going to Pirate, and will be ordering more in the next month or so. Look them up on the net.

When Pirate picks up his sheet, I'm sure there will be a very good review of this plywood. Andrew Denman will ship to the mainland, would have to contact him for freight costs to South Australia, but my last order was actually shipped free to the mainland, I had to pick up from Melbourne.

These sheets are not only excellent quality, but are also 2500mm long sheets, which as you may be aware, results in only 1 scarf being needed for Mozzies and other classes.

I have no affiliation at all with Andrew Denman Marine, but I've had marine plywood from all states on the east coast, and this stuff is the best I've seen and worked with, and its information worth sharing.
