Which patch is designed for relatively small holes?

• A. Hinge plate patch
• B. Soft patch
• C. Box patch
• D. EWARP patch

Answer: (A)

Relatively small holes are best handled with a hinge plate patch because its design lets you cover the opening quickly and securely with minimal fabrication. The patch has a hinge along one edge, so you can drop it over the hole, swing it into place, and fasten the opposite edge with bolts or clamps. This provides an immediate, mechanically fastened seal that’s easy to align and less likely to shift under water pressure, which is ideal when you’re patching a small breach and need fast control of flooding while you arrange a more permanent repair. Soft patches are flexible and useful in many situations, but they typically require additional soaking or sealing materials and can take longer to achieve a reliable watertight seal. Box patches are framed, more suitable for larger holes where a rigid, box-like insert is needed. EWARP patches are rapid, large-area solutions that create a strong, temporary seal, again more appropriate for bigger breaches than tiny ones.
