Dock Lines Explained:
What You Need to Know
The reliability of your vessel starts with a high-quality dock line. At American Rope, we offer premium dock lines designed to secure your boat effectively while providing durability, strength, and easy handling for all docking conditions.
Why Choosing the Right Dock Line Matters
Dock lines are more than just ropes—they are the lifeline that secures your boat to the dock, absorbing shocks from waves, wind, and tides. The right dock line ensures your boat stays in place while also prolonging the life of your equipment by minimizing wear and tear. Selecting the appropriate dock line is essential for safely securing your boat and ensuring its longevity.
Types of Dock Lines
At American Rope, we offer two primary types of dock lines, each designed to meet different needs and conditions:
Double Braid Dock Line
- Description: Known as “Yacht Braid,” this rope features a braided core and cover, offering high strength and easy handling. It’s made from 100% high-tenacity, marine-grade nylon fibers, providing excellent shock absorption and UV/chemical resistance. The rope is torsion-balanced, preventing hockling and maintaining stability.
- Features: Hand spliced eye, hand whipped at throat & bitter end, with high strength, predictable elongation, and excellent abrasion resistance. Ideal for larger boats and heavy-duty applications.
3-Strand Twist Dock Line
- Description: This durable, torsion-balanced rope is made from 100% high-tenacity, marine-grade nylon fibers. Its three equally sized strands are twisted together, offering excellent shock absorption, easy handling, and resistance to UV and chemicals. Ideal for general-purpose docking and smaller boats, this rope is manufactured entirely in the USA and features a 24" hand-spliced eye. The eye splice can be customized and standard eye size varies depending on the diameter of the rope.
- Features: Flexible and easy to handle, with excellent resistance to UV, chemicals, and abrasion. Its natural stretch absorbs shock loads, ensuring a secure and reliable hold while docking.

How to Choose the Right Dock Line
Selecting the right dock line depends on several factors, including your boat’s size, the environment where you dock, and the conditions you typically encounter. Here’s a quick guide to help you choose:
Boat Size:
Larger boats require thicker, stronger lines. For example, a 25-foot boat typically needs a 3/8-inch diameter dock line, while a 45-foot boat would need a 5/8-inch line.
Docking Conditions:
In rough waters or areas with strong currents, opt for a stronger line like the Double Braid. For calmer conditions, the 3-Strand Twist offers the flexibility you need.
Customization:
Consider customizing your dock lines with spliced eyes, chafe protection , or specific colors to match your boat and docking setup.

Protect Your Investment with Chafe Guard & Scuff Guards
Dock lines can experience significant wear and tear where they come into contact with rough surfaces or cause friction against the sides of your boat. To protect both your lines and your boat, consider adding Chafe Guards and Scuff Guards, which offer essential protection in high-wear areas and help maintain the longevity of your equipment.
Chafe Guards
We can also customize these with Light Grey Nylon Wear Pad or Black Leather for a luxurious look. Please call or email us to get a quote.

Frequently Asked Questions
Double Braid dock lines are made with a braided core and outer jacket, offering superior strength, smooth handling, and minimal stretch. They are ideal for larger boats or areas with strong currents. In contrast, 3-Strand Twist dock lines are known for their high elasticity, which makes them excellent at absorbing shock loads, ideal for smaller boats or in areas with rough conditions.
The 3-Strand Twist dock line is best for absorbing shock because of its elasticity. It stretches under load, which helps reduce the strain on your boat and dock hardware, making it a great choice for rougher waters or areas with significant wave action.
As a general rule, you should use 1/8 inch of line diameter for every 9 feet of boat length. For example, a 27-foot boat would typically use a 3/8-inch diameter dock line. For larger boats or those in heavy weather areas, you may want to go up in size for added security.
