Seachoice 3-Strand Twisted Nylon Anchor Line – 3/8 in. x 50 ft., White

Reliable Holding. Built for the Shock of the Sea.

When your boat is at anchor, the line between a peaceful night and a dragged anchor is the quality of your rode. This Seachoice 3-Strand Twisted Nylon Anchor Line is engineered specifically to absorb the dynamic shock loads that occur as waves, wind, and current tug at your boat — protecting your anchor hardware, cleats, and bow fitting from the stress that rigid lines transfer directly.

At 3/8 in. diameter and 50 ft. in length, this line is sized for day anchoring on smaller powerboats, runabouts, and fishing boats. The 3-strand twisted construction gives it natural elasticity and makes it easy to splice, coil, and handle on deck. It arrives with a professionally spliced galvanized thimble at one end, ready to shackle directly to your anchor chain or anchor.

Parts Desk Insights

• Best for: Smaller powerboats and day anchoring in calm to moderate conditions — the 50 ft. length suits shallow to mid-depth anchorages where a 5:1 to 7:1 scope is achievable
• Thimble note: The galvanized thimble protects the splice from chafe where it meets a shackle — always use a shackle, not a knot, at this end
• Sizing guidance: 3/8 in. is the minimum recommended diameter for boats up to approximately 20 ft.; step up to 1/2 in. for heavier boats or overnight anchoring
• 3-strand vs. braid: 3-strand nylon stretches more than double-braid, making it better for shock absorption but slightly harder to handle in cold or wet conditions
• Pairing tip: Add 4–6 ft. of anchor chain between this line and your anchor to improve holding angle and protect the line from bottom abrasion
