What planer boards do and when to use them

A planer board is a small, weighted platform that tows behind your boat on its own line, pulling your fishing line to the side and away from your boat's wake. As you move forward, the board planes outward at an angle—typically 20 to 40 feet to either side—and holds your lure or live bait at that distance. The board stays on the surface or just below it, and when a fish strikes, a release mechanism trips and frees your line so you can fight the fish directly.

Planer boards let you fish multiple lines at once without tangling, cover water that your boat would spook, and present baits at different distances from the boat simultaneously. They work best in open water where you need to spread out—lakes, reservoirs, and slow rivers—and are especially useful when trolling for walleye, pike, musky, and bass. They are less practical in heavy cover, shallow water, or tight quarters where you cannot maneuver freely.

Key Takeaways

  • Planer boards pull your line to the side of the boat on a separate tow line, keeping your fishing line clear of the boat's wake and other lines.
  • You attach your fishing line to the board with a release clip that trips when a fish strikes, freeing the line so you can set the hook and reel in.
  • Most anglers use one board per side of the boat and run two or three fishing lines per board, depending on local regulations and the board's weight capacity.
  • Planer boards work best in open water when trolling at 1 to 3 miles per hour, and they require a separate rod and reel to manage the board's tow line.
  • Proper line tension and release adjustment are critical—too loose and the board will not hold angle, too tight and the release will not trip when you hook a fish.

Types of planer boards and how they differ

In-line boards attach directly to your main fishing line and are pulled by the same line that holds your lure. They are simple and require no extra rod, but they are harder to manage when you hook a fish because the board stays attached until you reel it in. In-line boards work best for single-line setups and lighter lures.

Side planer boards run on a separate tow line attached to a dedicated rod and reel, leaving your fishing line independent. This setup lets you fish multiple lines per board and gives you better control when a fish strikes. Side boards are more versatile and are the standard choice for serious trolling.

Weighted boards sink slightly below the surface and hold deeper than surface boards, useful when you want your lure to run at a specific depth. Unweighted boards stay on the surface and are easier to see and manage, especially in rough water. Most anglers choose based on the depth they want to fish and the water conditions they expect.

Setting up your planer board rig

For a side planer board setup, you need a dedicated rod and reel to manage the board's tow line. Use a medium-power rod, 6 to 7 feet long, paired with a reel that holds at least 200 yards of 20- to 30-pound braided line. Braided line is preferred because it has less stretch, giving you better feel and faster response when the release trips.

Attach the tow line to the board's tow ring—a small eyelet on the front of the board. The tow line should be 40 to 60 feet long, depending on how far you want the board to run from the boat. Attach your fishing line to the board's release clip, which is usually a simple spring-loaded mechanism that holds the line under tension. When a fish pulls hard enough, the clip opens and your line slides free.

Set the release tension by adjusting the clip's spring or the position of the line in the clip. Start with light tension—the line should slip free with a steady pull of 2 to 4 pounds of force. If the tension is too light, the board will release on its own in rough water. If it is too tight, the release will not trip when you hook a fish, and you will reel in the board instead of fighting the fish.

Running multiple lines and managing depth

Most regulations allow two or three fishing lines per planer board, though you should check your local rules before setting up. Attach lines to the board at different points—typically one at the release clip and one or two on secondary clips positioned behind the main clip. Space them 12 to 18 inches apart to prevent tangling.

Vary the depth of each line by adjusting how much line you let out before the board reaches its running position. A line with 30 feet of lure behind the board will run shallower than a line with 60 feet out. You can also use different lure weights or diving plugs to control depth independently of line length. This layering lets you fish three different depths at the same distance from the boat, covering more of the water column without adding more boards.

Keep tension on all lines at all times. Slack line means the release will not trip cleanly, and you may miss the strike or have to reel in the board. Use line holders or rod holders to keep rods at a consistent angle, and check tension every few minutes, especially in rough water where waves can create slack.

Trolling speed and board angle

Planer boards work best at speeds between 1 and 3 miles per hour. Below 1 mile per hour, the board loses angle and may not hold its position. Above 3 miles per hour, the board pulls hard, creates excessive drag, and can become unstable in waves. Most walleye and pike trolling happens at 1.5 to 2.5 miles per hour, where boards track smoothly and lures have time to work.

The board's angle depends on speed, tow line length, and water conditions. In calm water, a board typically runs 20 to 40 feet to the side. In rough water or at higher speeds, the angle may increase to 50 feet or more. Watch the board's position and adjust speed or tow line length if it is running too close to the boat or too far out. A board that is too close will not separate your lines enough; one that is too far out becomes hard to manage and may not release cleanly.

Detecting strikes and setting the hook

You will feel a strike through the tow line rod, not through the fishing line rod. When a fish hits, the fishing line jerks the release clip open, and the tow line goes slack or becomes lighter as the board loses tension. Set the hook immediately by raising the tow line rod sharply, then switch to the fishing line rod to fight the fish.

Some anglers use a rod holder alarm or line counter reel on the tow line rod to alert them to strikes, especially when running multiple boards. A simple bell clipped to the tow line also works and costs nothing. The key is staying alert—planer board fishing requires active attention, not passive waiting.

After you land the fish, reel in the board on the tow line rod, reset the release clip, and return the board to its running position. This cycle repeats for each strike. In good conditions, you may reset the board dozens of times in a day, so practice the motion until it becomes automatic.

Common mistakes and how to avoid them

Running the release tension too tight is the most common error. If the clip does not release when a fish strikes, you will reel in the board instead of the fish, waste time, and frustrate yourself. Test the release on the water before you start fishing by pulling the line with steady pressure until it slips free. Adjust until it releases at a reasonable force—around 3 to 4 pounds.

Letting line go slack is another frequent problem. Slack line means the release will not trip, and you may miss strikes entirely. Keep tension on all lines by holding the rods at a consistent angle and checking frequently. If you are running three lines per board, the middle line is most prone to slack—watch it closely.

Running the board too close to the boat defeats the purpose. If the board is only 15 feet out, your lure is still in the boat's wake and you are not covering new water. Increase tow line length until the board is at least 25 to 30 feet from the boat, and adjust based on water clarity and fish behavior.

Frequently Asked Questions

Do I need a separate rod and reel just for the planer board?

Yes, for side planer boards. The tow line needs its own rod and reel so you can manage the board independently and detect strikes through the tow line. In-line boards do not require a separate rod because they attach directly to your fishing line, but they are less versatile and harder to manage when you hook a fish.

What happens if my planer board flips or capsizes?

A properly weighted board should not flip in normal conditions, but rough water or a hard turn can cause it. If it flips, reel it in, flip it back over, and reset the release clip. Some boards have a self-righting design that helps them recover on their own. Always check your board for damage before putting it back in the water.

Can I use planer boards in rivers?

Yes, but only in slow, wide rivers where you have room to maneuver and the current is not too strong. Fast current will push the board downstream and make it hard to control. Stick to rivers where you can troll at 1 to 3 miles per hour without fighting heavy current.

How do I know if my release clip is adjusted correctly?

Pull the line attached to the clip with steady, increasing pressure. It should slip free when you apply 3 to 4 pounds of force—roughly the weight of a small coffee mug. If it releases too easily, tighten it slightly. If it requires more than 5 pounds of force, loosen it. Test it on the water before you start fishing.

What is the difference between a planer board and a trolling sinker?

A trolling sinker hangs below your line and pulls your lure deeper, but it stays directly behind the boat. A planer board pulls your line to the side, away from the boat's wake, and lets you fish multiple lines at different distances simultaneously. Planer boards cover more water and are better for open-water trolling.
