Mahi Trolling Spread for Small Boats

No outriggers, no tower, no problem. A center console can pull a five-line spread that looks like a school of panicked baitfish — you just set it differently than a sportfisher does.

The principle

What a good spread is imitating

The objective when setting your trolling spread is to imitate a natural feeding scenario: a school of panicked baitfish. You do that by staggering different baits at different lengths behind the boat, so the whole spread works together as one unit.

Staggering also imitates the natural pattern of fleeing baitfish, where the weak or slower ones get separated from the group and become the easy targets. That straggler is what a mahi picks off.

Everything below follows from that. The distances create the shape of the school, and the bait selection fills it in.

On a big boat, outriggers do the spreading for you: they carry lines wide and hold them clear of the wash. A center console has to get that separation from distance and rod angle instead, which is why the setup below is built around how far back each bait runs and which holder it sits in.

Speed

Trolling speed for mahi

Mahi themselves are not particularly speed sensitive. They get caught on everything from high-speed wahoo lures to a piece of cut squid pitched under a weed patch. There is no magic speed that triggers a mahi strike.

Your baits are a different matter. Each one has a speed at which it swims correctly, and that is what sets your trolling speed. Ballyhoo are the most popular mahi bait, and they want 6 to 8 knots — fast enough to swim right, slow enough that they do not wash out. Put a more delicate bait in the spread and the whole boat slows to suit it. Our guide to trolling speed by bait has the full range.

Find the speed bait by bait

As each bait goes over the side, watch how it swims. Adjust the rigging until it swims well, then change the boat speed and watch how that affects it.

Try to determine how sensitive that bait is to boat speed, and choose a speed toward the midpoint of its range. Do not pick a speed that is barely fast or slow enough to make the bait swim well. The action changes as the bait drops back into the spread, and a bait that is only just working alongside the boat will not be working back there.

Pause as you drop each bait back and watch how it trolls. This is a learning process and you will get better at judging it over time.

What changes it during the day

The optimum speed moves with wave height, current speed, your trolling direction relative to the current, a bait's position in the spread, and the angle the line enters the water. Stay attentive to the action of your baits and adjust as necessary.

The setup

The five-line spread, no outriggers needed

This is a basic but effective spread for a center console with no outriggers — the stern corner holders, the gunwale holders and the T-top rod launcher are all you need. Build it in this order.

Two short flat lines: 30 to 50 feet back

Start with two rods in the rod holders on the stern corners. Once the baits are in the water, increase speed until they skip along the surface without spending too much time in the air. Place them out of the boat's wash, in clean bluewater, so their action is maximized and easy to spot.

Effective baits here: daisy chains, light plastic skirted lures, or feathered trolling lures.

Two rigger lines: 60 to 80 feet back

These go in the outside holders of the rod launcher on the back of your T-top, or on the gunwales near the stern — ideally in holders angled about 45 degrees outward. Sixty to eighty feet keeps them a safe but close distance outside your short flats.

Effective baits here: naked ballyhoo, skirted ballyhoo, or medium plastic skirted lures.

The shotgun: 200 feet back, down the middle

Depending on your layout, add a shotgun bait 200 feet back down the center of the spread, from the middle holder of your T-top rod launcher. Bigger baits such as larger skirted lures work well. This is often the most effective lure in the spread, because at that distance it reads as the straggler.

Use a reel with large line capacity here. You already have 200 feet out before the hookup.

Five lines, staggered, working together as one school.

Baits

Filling the spread with natural and artificial baits

A good trolling spread includes a variety of natural and artificial baits in a variety of colors. As the day progresses, adjust based on how the fish react.

Ballyhoo are one of the most popular natural baits for mahi. They can be trolled on a traditional pin rig, or rigged with a TrollTrue lure — a faster, easier way to rig a ballyhoo without pin-rigging, rubber bands or copper wire. That difference matters most when the action gets hot and you are re-baiting with fish still in the spread.

When the bite turns on

Re-bait without losing the school

Hook the bait, slide the lure on. No pins, wire wraps or rubber bands — so a bait that gets eaten goes back out while the school is still behind the boat.

Hookup

Keep trolling to put more mahi in the box

One of the most common mistakes when a mahi is hooked is the captain's instinct to stop the boat. Mahi are usually in schools, and you have a far better chance of doubling or tripling up if you keep trolling through the hookup.

Rather than stopping, reduce to half speed and keep trolling. That alone will drastically increase your chances of another fish.

With a large mahi you may have to stop and clear lines that start tangling. For that reason, keep a large spinning rod rigged with a pitch bait ready to cast while the first fish is being landed.

Working a pitch bait

Cast well clear of the hooked fish so you do not tangle. Retrieve fast and frantic, to create the chaos of fleeing baitfish. Bucktails, jigs or a diving bait all work.

If it produces another fish, keep at it until the bite goes cold, then go back to trolling.
