Pearson 39-2/Ericson 38-200/Tartan 37
I just looked at the spec sheet at www.pearsoninfo.net and it says "balsa core bottom" as well as "balsa core deck". Draw your own conclusion, but it sounds like all balsa core to me. Which was a surprise, I didn''t know any Pearson hulls were cored. The Pearson 39-2 was built by Cal-Pearson, but was still a Bill Shaw design. I believe the Tartan 37 is also balsa cored.
