01Basic concept of multi‑hook rigging
A multi‑hook rig connects several small baits (spear squid & cuttlefish) sequentially on a single line to create a natural motion in the water.
The key is to combine the braided line and the leader appropriately to balance strength and sensitivity. The braided line is made of PE (ultra‑high‑molecular‑weight polyethylene); at the same size it has a diameter about one‑third to one‑quarter of nylon or carbon, yet its tensile strength is 4–7 times greater.
Therefore it offers low resistance to water flow and excellent bite transmission sensitivity, making it the most used material in multi‑hook rigs.
02Choosing braided line and determining strand count
PE braided line sizes are expressed in denier. A common reference is size 1 ≈ 0.165 mm, size 1.5 ≈ 0.205 mm, and size 2 ≈ 0.235 mm in diameter.
Breaking strength is roughly size × 10 lb, so size 1.2 has about 12 lb and size 2.0 about 20 lb tensile strength. However, braided lines for rocky‑shore jigging use a ‘Max’ rating, so the actual strength often far exceeds the listed value.
Strand count (core count) directly affects strength and abrasion resistance. Switching from 4‑strand to 8‑strand increased casting distance by about 10.5%, and moving from 8‑strand to 12‑strand added another 4.7% improvement, according to tests (source: worldofjin.com).
- Too many knots can reduce knot strength by up to 40%
- If the leader size is too thin, it will break easily under shock
03Matching shock leader and size
Because knots significantly lower the braided line’s strength, choose a leader 3–5 times thicker than the PE size to absorb shock.
For example, when using size 1.2 braided line, connecting a carbon 4–6-go leader balances tensile strength and shock absorption. This is because PE is 4–7 times stronger than nylon or carbon at the same size.
Adjust leader size according to target species. For eging, 0.6–0.8-go; for olive flounder, 0.8–1.5-go; for sea bass, 2.5–3-go leaders are recommended (source: innak.kr).
04Practical multi‑hook rig setup steps
1) Choose an 8‑strand (or 12‑strand) main braided line, then attach a leader (carbon 4–6-go) 3–5 times thicker appropriate for the target species.
2) Tie 2–3 small baits (spear squid & cuttlefish) onto the end of the leader in a multi‑hook arrangement. Bait spacing is typically 5–10 cm, adjusted according to water flow.
3) Float the entire line in water and verify that the baits move naturally. After submerging, shake the line for 1–2 minutes to check bite sensitivity transmission.
