Offshore fishing represents the largest scale of recreational angling — boats running 20–50 miles from land, pursuing fish that can weigh hundreds of pounds, in open ocean conditions that demand seamanship as much as fishing skill. It’s among the most exciting and challenging of all fishing experiences, and it’s accessible to anyone willing to learn the right way.
Starting Right: The Charter Trip Path
The best path into offshore fishing is not buying a boat first. Take 2–3 full-day offshore charter trips with professional captains on well-equipped boats. You’ll learn:
- What offshore water looks like (current edges, temperature breaks, weed lines)
- How trolling rigs are set up and how strikes are handled
- What sea conditions feel like at 5, 7, and 10 knots
- What a properly equipped offshore boat looks like
- Whether you actually enjoy offshore fishing before making the investment
Full-day charter trips run $800–1,500 for groups of 4–6 depending on the region (Florida, Gulf Coast, the Carolinas, the Mid-Atlantic, and California all have excellent offshore charter industries). Split among a group, this is a reasonable education investment compared to offshore boat costs.
Offshore Target Species
Mahi-Mahi (Dolphinfish)
The most beginner-friendly offshore species — spectacular colors (yellow-green-blue), aggressive surface behavior, fast, and willing to bite. Found along weed lines and current edges from 100–1,000 feet. Schools of mahi-mahi around floating debris or sargassum weed are excellent targets. See How to Catch Mahi-Mahi.
Yellowfin Tuna
Tuna require finding the right water temperature and baitfish presence — more technical to locate, but among the most powerful fish in any ocean. Schools are found by birds, bait balls, and temperature breaks. See How to Catch Yellowfin Tuna.
King Mackerel (Kingfish)
A nearshore-offshore species that bridges inshore and offshore fishing. Found along the shelf edge and around nearshore reefs (50–150 feet) throughout the Atlantic and Gulf coasts. Excellent trolling and live bait target. See How to Catch King Mackerel.
Wahoo
One of the fastest fish in the ocean — reaches 60+ mph; brilliant blue-silver coloration; excellent table quality. Found in warm, blue water along temperature breaks and the Gulf Stream edge. Trolling fast (8–12 knots) with wire leaders and high-speed lures is the primary technique.
Offshore Techniques
Trolling (Start Here)
The entry-level offshore technique. The boat runs at 6–9 knots with lures or rigged ballyhoo dragging behind at various distances. Species strike the moving baits. The captain drives; the crew watches the rods. When a rod goes down, the chair angler fights the fish while others clear lines.
Trolling lure positions (spread): Short rigger, long rigger, flat lines (each side), and a center “shotgun” line farther back. Different depths and distances in the spread cover the water column and increase the chances of a strike.
Chunking for Tuna
When tuna are located (often at canyon edges 60–100 miles offshore), anchoring or drifting over productive structure and chumming with cut butterfish or bunker chunks brings fish to the boat. Baits are then fished in the chum slick — pieces of chunk bait on 40–80lb fluorocarbon leaders with no weight, drifting back naturally. The most reliable way to catch multiple large yellowfin tuna.
Kite Fishing
A kite suspends a live bait on the surface — the line from the kite holds the main fishing line vertical so the bait swims on the surface, creating a natural splashing action that drives sailfish and large mahi into a frenzy. Primarily used in south Florida for sailfish. More advanced; learn trolling and live bait techniques first.
Offshore Knots
The FG Knot connects braid main line to a monofilament or fluorocarbon leader — essential for offshore trolling and chunking setups. The Double Uni Knot is an alternative for connecting dissimilar line types. Both knots should be practiced and mastered before fishing offshore — improperly tied leader connections are a common source of lost fish.
