What Is Big Game Fishing and What Should You Know Before Your First Trip?

Updated

Big game fishing is offshore fishing for large, powerful species—typically billfish like marlin and sailfish, plus tuna, shark, and other heavy-tackle targets—using a crewed charter boat, heavy rods and reels, and often trolling or live-bait techniques. It suits travelers who are comfortable on open water and want a guided, high-effort day rather than a casual inshore trip. Beginners can join, but the crew does the heavy technical work; your job is to listen, follow instructions, and be ready for a physical fight with a fish.

How big game fishing differs from other fishing types

FishingBooker lists big game fishing alongside saltwater, deep sea, bottom, and fly fishing as distinct fishing types, which is a useful way to see where it sits. The differences that matter most are distance from shore, target size, and how much specialized gear is involved.

Dimension Big game fishing Inshore fishing Bottom fishing General deep sea fishing
Typical water Far offshore, open ocean Bays, estuaries, near-shore Offshore or reef, fishing the seabed Offshore, varies by trip
Main targets Marlin, sailfish, tuna, shark and similar large species Smaller coastal species Groundfish and reef species Mixed offshore species
Gear Heavy rods, large reels, harnesses Light to medium tackle Weighted rigs fished on the bottom Medium to heavy tackle
Physical demand High during a hookup Low to moderate Moderate Moderate
Crew role Central—rigging, driving, coaching Supportive Supportive Supportive

The practical takeaway: "deep sea fishing" is a broad category, and big game fishing is the heavy-tackle, large-species end of it. If you want a relaxed day with plenty of action on smaller fish, inshore or bottom fishing is usually a better fit.

Target species and what the gear involves

Big game trips are built around a handful of high-value species. The exact list depends on destination and season, so confirm targets with the operator before booking rather than assuming. In general, expect:

  • Billfish (marlin, sailfish): often caught and released; trolling or live bait.
  • Tuna: strong fighters, frequently a primary target on offshore trips.
  • Shark: sometimes targeted, with handling and release rules that vary by region.

Because these fish are large, the tackle is correspondingly heavy—stout rods, large-capacity reels, fighting belts or harnesses, and terminal gear the crew rigs for you. You generally do not need to own any of it; a charter supplies the equipment and the expertise. What you should expect is a briefing on how to sit in the fighting chair or brace against the gunwale, how to reel, and when to stop and let the crew assist.

What a big game charter typically includes and the skill expected

Charter listings on FishingBooker are organized around boat, crew, and trip type, and the site's review system (rated 4.8/5 across more than 31,000 customer ratings) is a reasonable starting point for judging operators. A typical big game charter includes the boat, captain and mate, tackle and bait, and safety equipment. What varies—and what you must confirm—is licensing, food and drink, catch policy (keep vs. release), and whether fuel or gratuity is extra.

Skill level: no prior experience is required for a crewed trip, but honesty helps. Tell the operator it is your first big game trip so they can match you to an appropriate boat and pace. The crew handles navigation, rigging, and fish handling; you handle the rod under their direction. The main non-negotiable is physical readiness—fighting a large fish can take a long time and real effort.

How to choose a charter or destination for a first trip

Use the same comparison discipline you would for any charter booking:

  1. Match the trip type to your goal. Confirm the listing is actually big game fishing, not a general offshore or bottom trip with similar wording.
  2. Check target species and season. Ask what is realistically in season on your dates; a destination famous for marlin may offer little of it off-season.
  3. Read recent reviews for the specific boat and captain, not just the destination.
  4. Confirm what is included and excluded—tackle, bait, license, food, catch policy, and gratuity expectations.
  5. Ask about sea conditions and cancellation policy before paying, since offshore weather can change plans.
  6. State your experience level and group size so the operator can advise on the right boat.

For destinations, use FishingBooker's destination and top-species pages as a starting filter, then verify seasonality directly with the operator. Do not treat a destination's reputation as a guarantee for your specific dates.

Costs, seasons, and practical preparation

Pricing is not published in the source material, so treat cost as something to confirm per listing rather than estimate. In practice, big game trips tend to be full-day or multi-day, private-charter bookings, which affects both price and how far in advance you should book. Seasons are species- and region-specific; always confirm with the operator.

Practical preparation:

  • Sea sickness: offshore trips are long and exposed; plan ahead if you are prone to motion sickness.
  • Sun and hydration: open-ocean days are harsh; bring protection and water.
  • Clothing and footwear: non-marking soles and layers for changing conditions.
  • Safety: follow crew instructions on harnesses, rails, and fish handling; release rules and protected-species regulations vary by region and must be respected.

If you want a first taste of offshore fishing without the heavy-tackle commitment, a general deep sea or bottom trip is a sensible stepping stone before booking a dedicated big game charter.
