Which risk significantly increased for 18th-century wooden ships during voyages into colder Arctic waters?

💡 Explanation

Hull failure from ice wedging occurred increasingly, because water expanded upon freezing within wooden hull seams undergoing freeze-thaw cycles, applying outward pressure until rupture. Therefore, ice wedging presents the relevant risk, rather than other temperature-sensitive failure modes or navigational errors.
