You do not need seven lines out to catch fish offshore. For most owner-operators and small crews, a well-run four-rod trolling spread catches more because every lure is in the right place and every bite can be handled cleanly. It is also the easiest spread to learn before adding a shotgun or teasers.
The four positions
- Short corner (port or starboard flat line): closest lure to the boat, run from a gunwale rod holder in the white water just behind the transom.
- Long corner (opposite flat line): a wave or two behind the short corner on the other side.
- Short rigger: from the outrigger on the same side as the long corner, a few waves back.
- Long rigger: from the other outrigger, the farthest lure back in clean water.
Staggering this way means each lure sits on its own wake wave and no two lines share the same lane.
Lure choices
- Short corner: the biggest, loudest lure. A large resin head or chugger that smokes hard in rough water.
- Long corner: a medium lure with strong action.
- Short rigger: a medium slant head or resin lure that dives and pops regularly. Often the top producer.
- Long rigger: a cleaner, straight-running lure or bullet for cautious fish.
Mixing sizes and actions shows fish a variety of profiles and helps you learn what they want that day.
Speed
Most four-rod spreads work best between 7 and 9 knots for marlin, tuna, and mahi. For a wahoo-focused spread, swap to heavy bullets and push 12 to 16 knots. Check every lure after any speed change.
Turning and clearing
With only four lines, you can turn more aggressively without tangles, which helps you work bait schools, weed lines, and color changes. On a strike, the driver keeps moving forward, the angler takes the bit rod, and the second crew member clears the remaining three lines starting on the side the fish is running.
When to add more lines
Add a shotgun when the sea is calm, the crew is experienced, and fish are wary. Add a teaser or dredge when you are targeting billfish and want to raise more fish. If adding lines causes tangles, go back to four.
Adapting the four-rod spread
- Mahi on weed lines: step down lure size and favor bright colors.
- Tuna on small bait: use smaller lures and a bullet on the long rigger.
- Rough days: pull lures closer to the boat so they stay in the water.
