Beginner's Guide to Offshore Trolling

Introduction

Offshore trolling is one of the most exciting ways to target big game fish like mahi-mahi, wahoo, tuna, and billfish. If you're new to trolling, the setup can seem overwhelming — multiple rods, lures, outriggers, and spread positioning all at once. This beginner's guide breaks it all down so you can hit the water with confidence.

The Basics of Trolling

Trolling means dragging lures or baits behind a moving boat at a set speed, usually between 6 and 9 knots for most offshore species. The goal is to cover water and find fish. Unlike bottom fishing or casting, trolling is a searching technique — you're presenting baits across a wide area until you find where the fish are feeding.

Essential Trolling Gear

  • Trolling rods — heavy-action conventional rods rated for 50–130 lb line
  • Conventional reels — two-speed reels with high line capacity (Penn, Shimano, Daiwa)
  • Braided main line — 65–130 lb braid for sensitivity and strength
  • Mono or fluorocarbon leader — 80–200 lb depending on target species
  • Skirted trolling lures — in a variety of colors and sizes
  • Ballyhoo rigs — rigged ballyhoo are one of the most effective offshore baits
  • Outrigger clips — to spread your lines and prevent tangles

Setting Up Your Trolling Spread

A basic 4-rod trolling spread for beginners looks like this:

  • Short rigger (left and right) — lures set 30–40 feet back, run off outriggers
  • Long rigger (left and right) — lures set 60–80 feet back, also off outriggers

Start with a mix of colors — pink/white, blue/white, and black/purple are proven offshore producers. Run larger lures in the short positions and smaller lures long.

Best Trolling Speeds

  • Mahi-mahi: 7–9 knots
  • Wahoo: 8–12 knots (faster is better)
  • Tuna: 6–8 knots
  • Billfish: 7–9 knots

Reading the Water

Look for temperature breaks, color changes in the water, floating debris, weed lines, and bird activity. These are all signs that baitfish — and the predators that follow them — are nearby. A good chartplotter with sea surface temperature overlays is invaluable for finding productive trolling grounds.

When You Get a Strike

When a fish hits, the rod will load up and the reel drag will start screaming. Clear the other lines quickly to avoid tangles, then fight the fish on the rod that's hooked up. Keep steady pressure and let the drag do the work — don't horse a big fish or you'll risk pulling the hook.
