How to pick the right one
Frequently asked questions
What is the most UV resistant material for dock lines?
Polyester and Dyneema blends, especially with UV inhibitors, offer the best UV resistance. Nylon is also good but degrades faster than polyester under constant sun.
How long do UV resistant dock lines last?
With proper care, premium UV resistant lines can last 5 to 10 years, depending on sun exposure and usage. Regular inspection is key.
What diameter dock line do I need?
For boats up to 30 feet, 1/2 inch is common. Larger boats may need 5/8 inch or more. Always check the manufacturer’s recommendations.
Can I splice my own dock lines?
Yes, many boaters splice their own lines. Some constructions are easier than others. Three strand and single braid are easier, while double braid is more complex.
What is the difference between three strand and double braid dock lines?
Three strand lines are more elastic and easier to splice. Double braid lines are stronger, have less stretch, and are more durable against abrasion.
Are snubbers worth getting?
Snubbers absorb shock loads and reduce stress on cleats and lines. They are beneficial in rough water or with heavy boats.
How often should I replace my dock lines?
Inspect before each season. Replace if you see fraying, cuts, or stiffness. UV damage often appears as faded color or fuzzy texture.
Can I leave my dock lines in the sun all year?
Even UV resistant lines will degrade over time. It is best to cover or store them when possible, but they are designed to withstand sun exposure.
Our take
For most boaters, the Yale Cordage Double Brait offers the best balance of UV resistance, strength, and durability, making it our top recommendation. If budget is a concern, the New England Ropes Three-Strand Nylon provides reliable performance at a lower cost.
