Which consequence results when Viking longship builders scarfed planks improperly?

💡 Explanation

Improper scarf joints lead to stress concentrations and hull weakness, lowering structural durability since the load transfer mechanism is compromised. Therefore, structural integrity reduces rather than sail degradation, rivet corrosion, or rudder control issues—properties decoupled from hull integrity given standard conditions.
