When stretch cannot be tolerated, which line should be used?

When stretch cannot be tolerated, Dacron is the preferable line to use due to its low stretch characteristics. Dacron, which is a type of polyester, is designed to have minimal elongation under load, making it ideal for applications where maintaining tension and control is crucial, such as in sailing or fishing. This quality is particularly important because excessive stretch can lead to loss of control or ineffective performance.

Polypropylene and nylon, on the other hand, tend to have higher stretch factors. Polypropylene can stretch significantly under load, which may compromise the reliability of the line in critical situations. Nylon, while strong and durable, also has a noticeable amount of elasticity, which can lead to stretch that might be undesirable in particular applications. This understanding of the material properties helps ensure that the selection of line remains functional and effective, especially when precision and control are paramount in boating or fishing activities.
