Wallace Mariner Seine Twine 1lb #21 Tarred
Wallace Mariner Seine Twine #21 in 1-pound spools delivers reliable, professional-grade cordage for fishing, net repair, and general rigging work. The tarred construction—a traditional treatment that's still standard across commercial and sport fishing operations—significantly enhances knot-holding strength, making this twine dependable when every tie matters. The black color and slightly tacky feel of the tar coating provide excellent grip and visibility, whether you're mending a seine, hanging gear, or securing loads on the water.
A pound of #21 tarred twine yields approximately 800 feet of working length, giving you substantial yardage for most repair and rigging tasks. The uniform tar coating means you get consistent performance across the entire spool—no thin spots or weak sections where knots might slip. This is utility-grade cordage, the kind commercial fishermen and serious anglers rely on because it works and doesn't quit.
If you're running nets, maintaining fishing gear, or rigging boats and camp equipment, tarred twine remains a proven choice. The tar treatment does reduce footage-per-pound by roughly 10–12% compared to untarred alternatives, but that trade-off buys you superior holding power and durability, especially in wet conditions where standard twine can weaken over time.
