Anchor Lines
Get Ready to Anchor with a Rope/Chain Anchor Line Package
The anchor line packages we offer are best understood in terms of an anchor rode, which is used to connect a boat to its anchor. Anchor rodes can be all rope, all chain or a combination of both. The term “anchor line” as used here refers to the nylon portion of the rode.
Anchor rodes generally consist of a long length of nylon line with an eye splice and a thimble to which is shackled a short length of galvanized chain. Alternatively, a rope-to-chain splice can be used to connect the chain to the line. Rope-to-chain splices are often used to enable the rode to be used with a windlass.
The most common line used for anchor rodes is three-strand nylon line, which is elastic and able to absorb the shock loads generated during anchoring. Double-braid nylon line can also be used. However, although it is stronger than three-strand nylon line, it is not as elastic. We also offer single-braid line pre-spliced to chain for use with Lewmar windlasses.
The anchor packages we offer generally include 150 feet to 300 feet of line, 6 feet to 30 feet of chain and two shackles. Rode packages are an easy way to buy everything you need for anchoring, except for the anchor.
What length of rode do you require?
Your anchor rode should be long enough to provide adequate scope for the deepest location where you anchor. Scope is the length of the anchor rode divided by the water depth and freeboard. At a minimum, your rode should provide at least 5:1, but preferably 7:1 scope. For example, if you are in 25 feet of water with freeboard of 5 feet and want to set an anchor with 5:1 scope, you will need a 150 foot rode. Adequate scope is required for an anchor to properly set and hold.
What size anchor line do you need?
A “ballpark” figure is 1/8 inch of line diameter for every 9 feet of boat length. However, this rule of thumb can vary with windage. Heavy or high-windage boats can use 1/8 inch of line for each 8 feet of boat length; and lightweight boats can use 1/8 inch of line for each 10 feet of boat length.

Anchor Lines FAQ
The best anchor line depends on your boat size and anchoring needs:
- Three-strand nylon: Offers excellent flexibility and stretch, making it ideal for absorbing shock from waves and wind. Best for general use.
- Double-braid nylon: Stronger than three-strand and smoother to handle, perfect for powerboats and high-load applications.
- Rope-to-chain combination: Provides extra holding strength and is often used with a windlass for easy retrieval.
Use the following rule of thumb:
- For normal anchoring conditions, use a 7:1 scope (7 feet of anchor line for every 1 foot of water depth).
- In rough conditions or high winds, increase to a 10:1 scope for better holding.
- For deep water or overnight anchoring, use additional scope as needed to ensure a secure hold.
Check your specific boat and anchor requirements for the best fit.
Stretch, or elasticity, helps prevent sudden jolts on your boat and anchor system by absorbing shock from waves and wind.
- Nylon anchor lines are preferred because they stretch under load, reducing strain on the boat and anchor hardware.
- Minimal stretch lines, like polyester, are not ideal for anchoring as they transfer more stress to the boat.
A rope-to-chain splice provides a seamless transition between the flexibility of rope and the holding strength of chain. Benefits include:
- Enhanced durability: The splice prevents weak points at the connection.
- Windlass compatibility: Smooth operation in electric anchor winches.
- Stronger hold: Chain helps keep the anchor at the proper angle for better holding power.
Regular maintenance extends the life of your anchor line:
- Rinse with fresh water after every use to remove salt, sand, and debris.
- Inspect for wear: Check for frayed or weakened sections and replace as needed.
- Store properly: Keep your anchor line dry and out of direct sunlight to prevent UV damage.
Yes, the type of water you boat in affects your choice of anchor line:
- Saltwater: Use marine-grade, UV-resistant nylon to withstand corrosion and prolonged sun exposure.
- Freshwater: Less demanding conditions mean a standard nylon rope will typically suffice.
- High-current or rocky bottoms: Consider adding a longer chain section to prevent abrasion.
