What types of patches are commonly used for temporary hull repairs?

Temporary hull repairs are crucial in emergency situations where immediate damage control is necessary to prevent further water ingress. The correct choice highlights the practicality and effectiveness of using wood plugs, rubber patches, and metal plates.

Wood plugs are often used to seal holes or breaches in the hull and can be effective in stopping water from entering a vessel. They are particularly favored because they can be fashioned quickly from readily available materials and are suitable for patching larger holes.

Rubber patches provide a flexible yet durable solution for minor leaks and can create a watertight seal when applied over compromised areas of the hull. Their resilience under various conditions makes them an ideal choice for temporary fixes, as they can accommodate some movement of the hull while maintaining their integrity.

Metal plates are another robust option for hull repairs. They offer considerable strength and can cover larger holes, providing a more permanent solution compared to other temporary measures. When secured properly, metal plates can withstand significant pressure, making them well-suited for various marine environments.

The other options, while they may have some utility in specific scenarios, either do not effectively contain water or are not practical for hull damage repairs. For instance, plastic sheets and duct tape are insufficient for enduring water pressure, while concrete and insulation foam are generally not suitable
