Which alternative method can be used for shoring if battens are unavailable?

When battens are unavailable for shoring, using wooden planks is a viable alternative due to their strength and accessibility. Wooden planks can provide the necessary structural support needed to stabilize and hold up damaged sections of a vessel. They are commonly found in marine environments, easy to cut to size, and can be arranged in various configurations to effectively distribute loads and provide adequate shoring. Unlike the other materials listed, wooden planks have the appropriate structural integrity and flexibility to function as temporary supports in damage control scenarios. They can absorb some movement and stresses without failing, making them particularly suited for this purpose.
