Secure Your Boat with Confidence
USA Rope 1/2" Pre-Spliced Dock Lines are the easiest and most reliable way to protect your vessel at the dock. Each line features a professionally spliced 12" eyelet, making it simple to slip over a piling, through a cleat, or around a rail. For added versatility, pair your dock line with an HMPE Soft Shackle to secure to unconventional attachment points.

Made in the USA, Professionally Spliced
Hand-spliced by our in-house rigging team using modern splicing techniques, each dock line delivers maximum strength and consistent performance. Proudly made in the USA, these dock lines are built with integrity and designed to last.

Choosing the Right Size
Industry standards recommend one-eighth inch of rope diameter for every 8–10 feet of boat length, depending on vessel size and weight. Heavier or taller boats benefit from the 1/8" per 8' rule, while lighter recreational boats are well-suited to 1/8" per 9–10'. This ensures proper balance of strength, stretch, and handling for every vessel.

Durability That Lasts Season After Season
Constructed from double-braided nylon, these dock lines resist UV rays, abrasion, mildew, and rot. Our urethane coating locks fibers together for snag prevention and adds an extra layer of protection. With superior shock absorption, these lines reduce strain on your boat, cleats, and pilings — providing reliable performance in all conditions and extending the life of your equipment.
