Considering advancements in marine materials and manufacturing, has anyone experimented with retrofitting older Chaparral models (pre-2005) with modern composite transom or stringer systems? Specifically, I’m interested in technical insight regarding the compatibility of cored composite replacements versus traditional marine-grade plywood in these hulls, potential challenges encountered during the process, and long-term performance outcomes, particularly in terms of structural integrity and weight distribution. Any documentation (before/after performance figures, construction photos, or layup process details) would be greatly appreciated for community knowledge sharing.
