What the AI looks for in Boat Dock Lines & Rope
- Fiber
- Use nylon. Nylon's stretch absorbs surge loads that would jerk cleats. Polyester stretches too little and polypropylene degrades in sun.
- Diameter
- Allow about 1/8 inch of diameter per 9 feet of boat length, and go up one size for heavy boats or exposed slips. This keeps chafe margin and strength appropriate to the load.
- Length
- Bow and stern lines should be roughly two-thirds of boat length. Spring lines should be at least boat length. Lines that are too short cannot be led at useful angles.
- Construction
- Three-strand is stretchier and easy to splice. Double braid is softer, stronger and kinks less. Pick based on your comfort with handling and splicing.
- Chafe protection
- Add chafe guards wherever a line crosses a chock or a dock edge. Chafe, not breaking strength, is what usually parts a dock line.
Brands that matter
- New England Ropes: Specialist rope maker.
- Samson: Rope maker with marine braids.
- Attwood: Widely sold packaged dock lines.
What to avoid
- Polypropylene dock lines
- Low-stretch polyester as dock lines in surge
- Lines without a spliced eye if you lack splicing skills
Questions
Three-strand or double braid?
Both work. Three-strand gives more shock absorption and DIY splicing. Double braid is nicer in the hand and resists hockling.
