Move the presentation
One or more lures or baits trail behind a slowly moving boat or human-powered craft. Boat speed gives the lure action and lets you cover water.
Fishing from a moving boat
Trolling Basics
Trolling is simply presenting a lure or bait while the boat moves. The beginner challenge is learning which part controls depth, which part attracts fish, and which part actually catches them.

The boat supplies the forward motion
Distance behind the boat
Setback is the amount of fishing line between the rod/boat and the presentation or release point. More is not automatically better; it changes lure depth, boat disturbance, and turning behavior.
Put gear in the fish layer
Depth can be controlled with lure design, line length, weights, lead-core/weighted line, diving devices, or a downrigger.
Controls action + depth
Speed changes lure action and often running depth. The correct speed is species- and lure-specific; use the water/species guide instead of assuming one universal trolling speed.
The common trolling components
Keeps the rod fishing
A secure holder keeps the rod angle consistent and frees you to control the boat. Keep rods positioned so they cannot be pulled overboard.
Measures repeatability
A reel that displays line-out distance helps repeat productive setback or weighted-line settings.
Reduces twist
A barrel or ball-bearing swivel helps when rotating attractors or lures would otherwise twist the main line.
Gets deeper
Clip-on weights, sliding weights, lead-core line, or diving devices pull the presentation below the surface.
Attractor + action
A dodger or flasher adds flash and movement ahead of the lure. On kokanee rigs, shorter leaders can let the dodger impart more action to a lure that has little action of its own.
Precise depth tool
A separate heavy weight carries the fishing line to a chosen depth. The line clips into a release, and a strike frees the fishing line so the fish is fought on the rod rather than against the heavy downrigger weight.
Start with the simplest method that reaches the fish
Main line → lure
Let line out behind the boat with little or no added weight. Useful when fish are shallow or when the lure itself dives.
Main line → weight/diver → swivel → leader → lure
Adds depth without a downrigger. Depth depends on weight, speed, line diameter/type, and line out, so repeatability matters.
Rod line clipped to downrigger release → lure trails behind
The downrigger weight controls depth while the fishing line separates from the weight after a strike.

Idaho Fish and Game notes that a basic dodger-and-lure setup can catch kokanee without expensive electronics or downriggers. Leader length matters because the dodger can transmit action to the lure; water-specific and lure-specific guidance should determine the final setup.
Trolling becomes easier when you change one thing at a time
Depth
First ask whether the lure is actually running where fish are holding. Surface temperature, season, structure, and species behavior can all change the target depth.
Speed
Watch lure action beside the boat before letting it out. Then use GPS, electronics, or another consistent speed reference so you can repeat what works.
Setback
Record how much line is behind the boat. Clear/shallow conditions may reward more separation; deeper downrigger fishing can often use less.
Turns
A gentle S-turn speeds the outside lure and slows the inside lure. Strikes during turns can reveal whether fish prefer faster or slower presentation.
A repeatable workflow
Check the legal number of rods and hook restrictions. Trolling rules and multi-rod permissions vary.
Rig before leaving the dock when possible. Loose hooks and leaders are harder to manage once the boat is moving.
Set a controlled boat speed. Confirm your lure has the intended action before sending it back.
Deploy one rod at a time. Set depth and setback, place it securely in the holder, then add another rod if legal and manageable.
Record productive settings. Depth, speed, setback, lure, color, location, and turns are more useful than remembering only that you caught a fish.
Net the fish deliberately. Keep the boat under control, maintain steady rod pressure, and avoid wrapping another trolling line around the fish or net.
