Wood cored GRP

[bg9208]

I am trying to find out which GRP boat manufacturers during the 70s 80s and 90s did and, coversely did not build hulls with wooden cores. I have started trying to build a list but information from GRP boat builders does not always state whether cored or not. Does anyone here know if such a list exisit?

Does anyone here know if such a list exists?

I'm sure such a list does not exist. Some did and some didn't. Some did for a while then stopped. Some switched over to other core materials as they felt they wanted / need to do so. To make such a list you would need to research all boats made over the past years year by year. No small undertaking as so many went out of business. "Wood" could be defined a lot of ways. Balsa is wood and many assorted plywoods have been used.

If you were making such a list I would think adding more information would be possible since you will be going through a lot of boat building details. In addition to the material there is also the process used, associated fibergalss, and resins.
