When patching holes in a vessel's hull, which materials are suitable as gaskets?

When patching holes in a vessel's hull, soft materials like pillows or bedding serve as suitable gaskets due to their ability to create a tight seal. These materials can easily compress and conform to the shape of the hole, helping to prevent leaks. Their softness enables them to absorb any irregularities in the surface and provides an effective barrier against water intrusion.

On the other hand, while wooden planks and metal sheets can be used as patches, they do not provide the flexibility and sealing capability of softer materials. Additionally, rope and lines may not have the structural properties required to create a reliable seal, as they are designed primarily for binding rather than for sealing potential water leaks. Thus, using soft materials is critical for ensuring an effective and secure repair of the hull.
