An acceptable method of temporarily sealing a crack formed in the hull of a vessel is to __________.

Correct Answer: Option C — apply a patch of sheet packing backed by a strong back or shoring

Temporary hull repairs require a method that seals the breach without inducing further stress. Applying sheet packing over the crack, secured by a strong back or shoring, effectively stops water ingress while distributing the load across the surrounding plating, avoiding the thermal stresses associated with welding on a compromised hull.
