Which problem impacted large wooden ship construction prior to readily available iron fasteners and sealants?

💡 Explanation

When wood in ship construction was subject to moisture and lacked proper fastening, galvanic corrosion occurs because dissimilar metals were in contact inside a hygroscopic conductive moist wood electrolyte environment leading to accelerated wood decay and subsequent joint loosening . Therefore, decay in joints is the predominant issue, rather than expansion, emissions, or UV issues, which are separate degradation mechanisms.
