The Commercial Longline Groundline 3/8 Inch is purpose-engineered for heavy longline gear systems where a robust, weighty groundline is the preferred configuration. It delivers higher line weight than smaller diameter alternatives, providing superior seabed holding power, and is ideally suited for bottom-set longline fishing operations in areas with strong underwater currents.
Constructed with a precision multi-strand twisted nylon build, this 3/8'' twisted nylon longline ground rope strikes an optimal balance of operational flexibility and heavy-duty abrasion resistance. It feeds smoothly through all standard manual and hydraulic longline hauling equipment, maintaining consistent performance and reducing friction wear throughout routine commercial fishing shifts.
Widely adopted as a standard specification in Alaska commercial fisheries, this heavy-duty bottom longline main line is perfectly sized for targeting halibut, sablefish and a full range of deep-dwelling groundfish species. It can be supplied in pre-cut fixed lengths for direct rigging use, or in continuous large coils for on-board custom cutting, depending on customer operational requirements.
As a fully configurable nylon longline trunk line, it can be fully tailored to match your specific vessel gear setup. Customizable parameters include overall length, twist lay direction, line color, end termination treatment and bulk packaging configurations, all built to align with your existing longline system and workflow.
