Pearson 39-2/Ericson 38-200/Tartan 37
We really like the T37. It ended up on our short list of finalists. (Although we bought a different boat from the short list)
Coring to the waterline is actually a pretty good idea. Provides insulation (sound & temp) above the waterline, plus stiffness to the hull. At the same time reduces risk of core leak/damage during less than catostrophic groundings.
