[Public-List] V-Berth Shelving

[Jason S via Public-List]

I believe for ultimate strength the marine ply is necessary. With regular
ply, especially the cheaper stuff, some of the voids are just ridiculous. I
cut some at work the other day....and voids were absolutely unbelievable.
So for bulkheads I believe in that situation there would be no substitute.
