The rope on your boat takes constant strain from saltwater, sun, abrasion, and load cycles. We stock marine rope for exactly that: dock lines, mooring lines, anchor rode, sailboat rigging lines, and marine accessories from manufacturers who build specifically for the water.
ROPE.com sells marine rope by the foot and in pre-cut lengths. No minimum orders. Pick the diameter, pick the length, and we cut it to order.
Dock lines take constant strain from tides, wind, and wakes. Nylon is the standard material because it stretches under load, which absorbs shock and protects your cleats and hardware. Double braid nylon is the most common construction for dock lines. 3-strand twisted nylon is a cost-effective alternative that is easy to splice and handles well.
Mooring lines face the same demands but often run longer and heavier. Diameter depends on boat length and displacement. As a general rule, use 1/2″ for boats up to 30 feet, 5/8″ for 30 to 45 feet, and 3/4″ or larger for anything above that.
Anchor rode connects your boat to the anchor. A nylon anchor line absorbs shock from waves and wind gusts. Most setups use a combination of chain at the anchor end and nylon line running up to the boat. 3-strand twisted nylon is the standard because it stretches well and is easy to splice to chain.
Sailboat rigging lines need low stretch for control and consistent handling under load. Polyester double braid is the standard for halyards, sheets, and control lines. High-performance blends with Dyneema or Spectra reduce weight and stretch further for racing applications. Yacht ropes from Marlow and New England Ropes cover everything from cruising to competitive sailing.
Nylon stretches under load and absorbs shock. The standard for dock lines, mooring, and anchor rode.
Polyester has minimal stretch. The standard for sailboat running rigging, halyards, and sheets.
Polypropylene floats, which makes it a common pick for ski tow lines, dinghy painters, and anywhere buoyancy matters. Not as strong or long-lasting as nylon or polyester.

We stock marine rope for saltwater and the constant load cycles that come with life on the water. We carry dock lines in nylon double braid and 3-strand, mooring lines for permanent and semi-permanent slips, anchor rode in 3-strand twisted nylon, and sailboat rigging lines in low-stretch polyester and high-performance blends.
Nylon dock lines absorb the shock of tides, wind, and passing wakes. Double braid nylon is the most popular construction for its handling and durability. 3-strand twisted nylon is a proven, spliceable alternative. We stock both in diameters from 3/8″ through 1″ and cut everything to length so you get exactly what your slip requires.
Mooring lines, anchor lines, rigging lines, and marine accessories are all available by the foot. No pre-packaged bundles. Questions about sizing? Our team can help you match rope to your boat.
