Interesting little article on Wood vs. Composite cores
See article
More support for the "Wood is Good" Theory !!!
Note the last sentence on the first page [img]/images/graemlins/smirk.gif[/img]
Plus read the second page on Cold-molding. Notice towards the end of the article :
Method of manufacture / weight / strength ratios …interesting and further support for wood.
A little FWIW
I talked to Greenwood (real nice people to talk to ) over a year ago ….but felt ( given the extra cost, and at that time, the hassle of acquiring a sheet or two as the closest dealer in the east was over 500 miles away) properly handled/prepped plywood would suffice. I can see Boat manufacturers using this stuff …why not I would (got the impression many pontoon boat builders used it for floor and deck work). The warranty thing looks nice ….but my interpretation after discussion with them is they will only replace the plywood, which makes sense ….guess who pays for the thousands of dollars, in the case of a transom, tear down and reconstruction. So
IF there is problems who cares about the minimal cost of the plywood. I still have end grain balsa and plywood that looks new after 28 years. As long as holes and such are properly repaired and sealed the core is in great shape. If I could get this stuff at a mill shop or lumberyard and it wasn’t over the top in cost vs. say a sheet of marine grade I’d use it … but at the time that wasn’t the case.
just an opinion !!!
