Key Features to Look For in a Nylon Dock Line

When shopping for dock lines, don't just buy the first nylon rope you see. Look for these features:

• Three-Strand Twist vs. Braided: For dock lines, Three-Strand Twist is the most common and recommended type. It's easier to splice, has excellent elasticity, and is very durable. Braided lines (double or single) are softer and easier on the hands but are typically less elastic and more expensive.

• Diameter: This determines the line's strength. The size is based on the length and weight of your boat. A general rule of thumb:

  • Up to 25 ft boat: 3/8" (10mm)

  • 25 - 35 ft boat: 1/2" (12mm)

  • 35 - 45 ft boat: 5/8" (14mm)

  • 45 ft and larger: 3/4" (16mm) and up

  • When in doubt, go a size larger. Thicker lines are also easier to grip and handle.

• Length: You need a minimum of four lines: two bow lines and two stern lines. Spring lines are also highly recommended.

  • A good starting length for bow/stern lines is the length of your boat.

  • Spring Lines (which prevent forward/aft movement) should be about 1.5 times the length of your boat.

  • It's always better to have a line that's too long (you can double it up or take extra turns on the cleat) than one that's too short.

• Construction Quality: Look for tightly woven strands with a consistent feel. The line should be supple but not overly stiff.

• Spliced Eye: A pre-spliced eye on one end is a huge convenience and safety feature. A spliced eye is much stronger and neater than a knot. The eye should be the correct size for your cleats—large enough to fit over the cleat but not so large that it slips off easily.

• Why Nylon is the Gold Standard for Dock Lines

  Nylon is overwhelmingly the best material for dock lines for several key reasons:

  1. Elasticity (Shock Absorption): This is the most important feature. Nylon can stretch up to 15-20% under load. This elasticity acts like a shock absorber, soaking up the energy from waves, wind gusts, and wakes from passing boats. This prevents sudden, jarring loads on your boat's cleats and deck hardware, protecting both your boat and the dock.

  2. Strength: Nylon has a very high strength-to-diameter ratio, meaning it's incredibly strong for its size. A relatively thin nylon line can hold a very heavy boat.

  3. Durability: It is highly resistant to abrasion, UV radiation, and rot, making it well-suited for the harsh marine environment.

  4. Cost-Effective: While not the cheapest initially, its longevity and performance make it the best value.
