What this video covers
C&C 110, 115, and 121 models utilize vacuum-bagged, epoxy-based composite sandwich construction with structural foam cores like Corecell to achieve high stiffness-to-weight ratios.▶ 3:20 While this design provides superior performance and responsiveness compared to traditional solid fiberglass hulls, it introduces specific structural risks, primarily delamination from hard impacts and water intrusion through unsealed deck fittings, chain plates, or through-hulls.▶ 3:40 Although the manufacturer utilized solid fiberglass in high-stress areas like keel attachments, moisture migration can still compromise the bond between the fiberglass skins and the core, leading to soft spots and potential freeze-thaw damage in colder climates.▶ 5:57 Prospective buyers should prioritize a professional survey that includes moisture readings and a thorough inspection of all hardware penetrations.▶ 8:24 Because some buyers avoid cored hulls due to perceived maintenance requirements and resale difficulty, owners must document consistent care to maintain market value.▶ 7:28 Proper maintenance of hardware bedding and structural integrity is essential for the long-term viability of these performance cruisers.▶ 6:25
