Swordfish Light Attachment and Placement
Correct attachment keeps the light visible while reducing tangles and interference with the hook, leader and bait. Placement should follow local regulations, vessel procedure and the characteristics of the light.
NOAA describes pelagic longlines as a mainline with gangions and baited hooks. A NOAA technical report on Hawaii gear describes buoyant luminescent lightsticks positioned approximately two to three meters from the hook in one swordfish configuration. Other documented fisheries use different distances, so this figure should be treated as an example rather than a universal rule.
Placement Principles
Keep the light clear of the hook
The light should not obstruct bait movement, hook exposure or leader handling. Confirm that the attachment cannot slide toward the hook during setting or soaking.
Maintain consistent spacing
Consistency makes performance easier to compare. If each branch line uses a different distance, it becomes difficult to determine whether results came from the light, the bait or the placement.
Prevent line damage
Avoid attachment methods with sharp edges. Clips, bands and connection points should be checked for abrasion before the gear is deployed.
Consider buoyancy and orientation
The product’s buoyancy and attachment orientation may change its position relative to the bait. Test the full rig beside the vessel before adding units to a large set.
A Simple Deck Check
- Inspect the XC188 housing and attachment point.
- Secure the unit using the vessel’s approved method.
- Pull-test the connection.
- Confirm that the light does not contact the hook point.
- Activate or wet-test according to product instructions.
- Record the placement distance for the set.
The XC188 landing page provides a focused destination for customers researching the unit. For alternative shapes and attachment systems, compare disposable LED fishing lights and battery-powered lights.
Compliance Comes First
Rules governing hooks, lightsticks and protected-species measures vary. NOAA’s North Atlantic swordfish profile summarizes U.S. management measures, including permitting and bycatch-reduction requirements. Operators should consult the authority responsible for their fishing area before changing gear.
