: I built two kayaks about five years ago using 1/8" luan and it
: worked just fine. I used 4oz glass on the deck and the inside
: and outside of the hull. The boats are 18' (Chris Cunninghams
: Greenland design) and upon completion each weighed in at 42
: pounds. I easily found all the voids in the plywood by shining a
: light through it (100 watt bulb) and after marking them out just
: avoided using those areas. I have to admit the boats are showing
: some wear due to the fact they have been kept outside most of
: their life (I need a bigger garage) but otherwise they have
: served my wife and I just fine. After I get a new garage built
: I'm planning to build a couple of fresh boats and I might just
: use luan again!

Plywood quality has gone very rapidly downhill in the past few years, most domestic stuff is just garbage. I used to use luan too, but no more.
