Heavier Gauge Anchor Rode for Larger Boats
The Seachoice 3-Strand Twisted Nylon Anchor Line steps up to 1/2 in. diameter for boaters who need a beefier rode — whether you're running a heavier anchor, dealing with stronger currents, or simply want more confidence in your holding system. At 100 ft., it provides solid scope for most anchoring situations in moderate depths.
Three-strand twisted nylon is the preferred construction for anchor rodes because it stretches under load, cushioning the jolt of wave action and wind gusts before that force reaches your cleats or anchor hardware. The integrated blue tracer gives you a quick visual reference for wear and UV degradation over time — a practical feature that braided lines don't offer.
A pre-installed galvanized steel thimble at the anchor end means you can shackle directly to your chain or anchor without any additional rigging. The white nylon resists UV, salt, and abrasion, and the line floats clear of running gear.

Parts Desk Insights
The 1/2 in. diameter is the right step up from the 3/8 in. line when your boat or anchor is on the heavier side — the larger diameter handles higher loads and resists chafe better in rocky or coral anchorages. At 100 ft. this is a practical length for most coastal anchoring; if you need more scope for deeper water or overnight stays, consider the Seachoice 1/2 in. x 200 ft. 3-Strand Anchor Line. For a lighter setup or smaller boat, the Seachoice 3/8 in. x 150 ft. Anchor Line offers more length at a lower weight. Pair with a Seachoice Navy Anchor or Seachoice Galvanized Claw Anchor for a complete system. The thimble is already installed — just add a shackle and you're ready to drop the hook.
