I have use Merton's and Fiberglass Supply for online or phone purchases of balsa and related repair supplies. Fiberglass Supply is located in Burlington WA and has an extensive web site with great descriptions of the materials. If you purchase larger volumes of balsa or other bulky materials the online shipping calculator will give a high shipping cost quote. Call by phone and ask for Jose' to manually calculate UPS charges. When we purchased a large quantity of vacuum bagging materials Calypso's co-owner drove 2 hours each way to save $180 in shipping.
I do not recommend expandable foam for a structural repair. There have been some very helpful discussions on the Sailing Anarchy Fixit Forum regarding cored deck repairs. One of the take away points for me was to use similar materials when performing repairs. When you start your project, evaluate how wet and the overall condition of the balsa before fully charting your course. If the balsa is damp (<30% moisture per the Baltek web site) and still looks tan and smells like balsa with a polyester undertone it may be OK to make small repairs around the deck penetrations. If you are able to go this route, be aware it is difficult and slow to dry out large areas of balsa using only the fastener holes. Let me know if you are interested in more balsa repair techniques / info learned from making extensive repairs to Calypso's deck.

I have some wet spots in the area of port genoa track(aft section). Interestingly the other side is dry. I thought I would order the core ahead of time. But after haul out, I’ll wait to dig stuff out before ordering. I’m not very motivated to do this, but it needs to be done. Did anyone use expandable polyurethane foam for coring? Merton’s Fiberglass sells it.

When I installed the windlass I found the centerline, where a staysail track was, has plywood reinforcement about 3" wide.

When replacing failed balsa I have been purchasing 1/2" then sanding it down a little to leave room for epoxy and filler and the new epoxy/glass laminations. If you remove a fastener in the general area of the deck you would be able to verify that C&C did not use different thicknesses in newer designs/builds.
