Joel, I expect we experienced similar paths in restoring/repairing C&C designs built by Bruckmann. The “stick built” interiors give both easy access for water migration and for the repair work water migration makes necessary. I have a declared value marine insurance policy to cover liability and some hull losses but fully expect a tussle if I were to file a total loss claim.
One of the key failure modes we experienced was caused by water gaining access to the channels created when the Bruckmann build team bonded bulkheads to the hull. We found water** that pooled in the bilge forward of the mast migrated across the bottom of several bulkheads and, over 40 years, rotted the ¾” thick plywood up to 18” from the hull contact. Did you find any evidence of water migration through the bulkhead channels of the embedded 12v wires run through the deck balsa core? Maybe Bruckmanns build practices were updated by 1973. Martin DeYoung Calypso 1971 C&C 43 Seattle/Port Ludlow **Calypso’s excess water forward of the bilge was cause by hull laminate fractures likely caused by years of hard competition and excess use of hydraulic backstay/babystay adjustors. When we first launched Calypso in Seattle (after trucking out from Chicago) water seeped into the bilge space forward of the mast step. We re-hauled the hull (the mast was out for painting and new rigging) and started diagnosing the failure by chiseling out the orange polyester “bog” filler and grinding off bottom paint. The micro fractures became appearant most easily inside. We re-laminated the hull in that area with epoxy, built up the well forward of the mast step, and re-faired the hull. Using as built drawings from C&C (from the museum I bought all available for 43s and some for the first few 60s) during Calypso’s current restoration we discovered 43 and 60 hulls after #1 and #2 were retrofitted or built with extra reinforcement in this area. For Calypso we manufactured “I” beams from G10 epoxy board and wood then glassed them to the hull from next to the mast step forward past the babystay’s interior anchor point.
