@amazeifystore: How could a tiny crack split an entire ship in winter? ❄️ Liberty Ships exposed a dangerous metallurgy mismatch: steel that stayed tough in warm water could become brittle in freezing conditions. A crack at a square hatch corner met concentrated stress and raced through the welded hull, while riveted joints often helped stop cracks. The hard lesson: strength ratings mean little if temperature changes how materials fracture. Would you trust a welded hull after seeing this?
