Based on the C&C 43 drawings I purchased from the Maritime Museum of the Great Lakes the C&C team learned from early hull experiences and added reinforcements on later hulls.
Maybe an earlier 35-1 owner reported an issue and the extra stiffener was added to later hulls. From the pictures it looks well sealed. As part of the ongoing restoration projects on Calypso we are adding the reinforcements shown on the drawings (some hand drawn in), especially just forward of the keel where we already repaired some fractures in Calypso’s hull back in 1999. From several C&C 61 drawings I purchased, both hull #1 of the 61’s and Calypso, hull # 1 of the 43’s had the same flaw and needed the same reinforcements. I could not determine which hull number of the 43’s first received a “factory installed” reinforcement but I expect it was not in time for hull #’s 2 and 3. When launched, as “Arieto” in early 1971, our 43 was racing in the SORC within a few months. I expect no mercy was shown regarding backstay and rig pressures in securing that year’s 1st in class (10th in fleet) wins. It likely started to show some unexpected hull flex as difficulty in holding forestay tension. IIRC hull #1 of the 61’s was Sorcery. If so, I expect Sorcery was raced hard enough, with high enough hull and rig forces to precipitate an early issue that lead to other boats being inspected and the design team working out the fixes.

Subject: Stus-List 35-1 Cored Hull? Yeah, I know, the 35-1 is not a cored hull. Well, not 100% true. In the process of re-configuring Touche' batteries to add a dedicated start battery, I pulled everything out of the aft dinette storage. While the space was empty. I thought I'd grab a picture of the strip of core that is at the aft end of the keel. There's a matching strip on the other side. https://drive.google.com/open?id=0B_sb5TfIENvsWmZjYUJwNzBfMTA This extra structure adds strength at the aft end of the keel in case of a hard grounding.
