For Viking longships navigating fjords, which risk increased nearest shore during tacking maneuvers?

💡 Explanation

Sail luffing increased, causing speed loss, because the venturi effect is disrupted between the sail and cliff face; therefore, limited rudder authority increases grounding risk, rather than seabed strikes being relevant in deeper fjord channels.
