Does anyone else get frustrated with the quality of Marine ply. Just received from Wellington supplier some Gaboon ply supposed to be suitable for Boat Building - specifically told the supplier what it was for. Yes they had some nice 5 ply with Gaboon face and unspecified hardwood cores sounded Ok until it arrived. The face ply's are paper thin so in reality only three ply. To use this you have to hope that the glue holding the face ply's is pretty good, as this what ends up holding everything together. Living in Central Otago we do not have the luxury of going into the supplier and having a look first. All wholesalers of plywood are on the other side of Cook Strait so us Southerners end up paying $60 - $100 in Freight.
There has to be a more reliable way of purchasing plywood. Is their some way as a group of enthusiasts we could come up with a group buying scheme from a supplier that understands our needs.

Why bother with so called marine ply? I've been building dinghies for years and for about the last 15 have used ordinary construction ply. I've never had a problem with it delaminating- after all the same product survives the pressure treatment vats. I also prefer un-treated because the sheets are not distorted from the treatment process. It might be different if they were submerged for long periods say at a mooring. But hey, 'marine' plys aren't treated either. I also use exterior PVA glue for just about all wood joints these days. I can hear the howls of horror from experts already. But I've never had a boat or guitar fall apart- which is more than I can say for some of the 'repairs' I have re-done where epoxies etc were previously used.
