I you are interested in Marine Grade plywood, check out Wooden Boat magazine.... http://media4.hypernet.com/~WOODENBOAT/wb.htm The classified ads are full of wood suppliers. Very high quality publication.

I have been diligently studying the plans and am at the point of ordering materials. I have questions regarding plywood. Is there a significant difference between "marine" plywood and aircraft grade mahogany or birch?? Also can anyone suggest sources of spruce other than aircraft spruce? Are there any spruce suppliers on the east coast? Thanks ----------------------------------------------------------------------
