Which risk increased for Vikings negotiating shallows when complex running rigging degraded?

💡 Explanation

Loss of integrity causes rigging failure because friction increases as fiber breaks lead to tangling; this directly impacts sail adjustments via friction, and thus maneuverability. Therefore sail mismanagement increases, rather than rudder/hull problems that predate rigging issues.
