Backbone 1.8mm Stoppered Longline – Bulk 3000m Spool

Engineered for serious offshore longline operations, this Backbone 1.8mm Stoppered Longline delivers a precise balance of flexibility and high-tension strength you can rely on from the first set to the final haul. Supplied on a rugged 3000 metre bulk spool, its 1.8 mm nylon mono backbone is built to perform under demanding conditions and against large pelagic and demersal targets.

• Diameter: 1.8 mm nylon monofilament backbone for dependable load handling
• Spool length: 3000 metres on a single, robust bulk spool
• Stopping system: Stoppered at 1.5 metre intervals for repeatable hook spacing
• Stopper construction: Manually tied and glued stoppers for maximum durability
• Breaking strength: Approximately 190 kg / 420 lb
• Origin: Developed to meet Norwegian commercial fishing standards and trusted worldwide

The fixed 1.5 metre stopper spacing isn’t just a rigging detail—it’s a practical advantage. It ensures uniform hook distribution along the entire longline, reduces wear at stopper points, and minimizes slippage even when the line is under heavy load. With pre-stoppered intervals, field labor is streamlined, downtime is reduced, and you can expect consistent behavior across longline runs from the first buoy to the last.

Ideal for fleets that target tuna, halibut, and other large pelagic and demersal species, this backbone provides a reliable backbone for offshore rigs, charter operations, and serious recreational fishers building or upgrading longline setups. It pairs strong, high-tension performance with smooth handling during setting and hauling, helping you maintain efficient lines and steady catches over long deployments.

Why choose Sea fish Backbone for longline work: decades of field-tested engineering behind a product designed to endure harsh offshore environments. You get predictable performance, durable stoppers, and consistent line behavior—crucial when every set matters.

Practical usage tips: store the bulk spool in a dry area, inspect stoppers periodically for signs of wear, and ensure the line remains free of nicks to preserve tensile strength across longline runs. This 3000 metre spool is built to keep you in operation, from the opening drift to the final haul.
