Quick Answer
Tarred bankline does not absorb water like other ropes. It resists water penetration due to the tar coating on the cordage. Tarred banklines are often used in marine applications where moisture exposure is a concern.
Water Resistance Characteristics
Tarred banklines have a high level of water resistance due to the tar coating, which can reduce water absorption by up to 90%. The tar coating acts as a hydrophobic barrier, preventing water from penetrating the cordage. This makes tarred banklines suitable for use in wet or humid environments.
Comparison to Uncoated Ropes
In comparison, uncoated ropes can absorb up to 50% of their weight in water, leading to significant weight gain and potential damage to the rope. Tarred banklines, on the other hand, can withstand exposure to water without compromising their structural integrity. This makes them a reliable choice for applications where moisture exposure is a concern.
Maintenance and Durability
To maintain the water resistance of tarred banklines, it’s essential to apply additional coats of tar as needed. Over time, the tar coating can wear off, exposing the underlying cordage to water. Regular maintenance can help extend the lifespan of tarred banklines, which can last up to 10 years or more with proper care.
