I would say Miss OSB is all that and a bag of chips. All that now, and a bag of chips in fourty years. I can imagine how much fun it would be to try and dissasemble and pattern.

For thousands of years men have felt the irresistible urge to go to sea, and many of them died. Things got better after they invented boats.

It may be OSB, but look at the spec. The OSB is hardwood chips in WEST resin. Not the stuff we can go and buy. It's probably better quality than the marine ply we buy.

Tom, Yes, the OSB was encapsulated in epoxy but per the article, it was done after the OSB was made using traditional resins. Getting epoxy through a OSB manufacturing line would be a big problem. The use of "hardwood" chips of flakes I'm sure was done for color and not strength. There are many soft woods like Sitka Spruce or even Doug fir that are higher in tensile than many hardwoods like some Mahogany's. |

Jack, I forgot to pull out my Gougeon book yesterday when I got home yesterday. Hopefully, I can find it - I haven't used it since the days when everyone was finding out that the West system bottoms were failing. I'll look for it today. |

Thinking this topic has been pretty well pulverized.
