One of the Most Prized
Game Fish in the Pacific

Aloha, and welcome to yellowfin tuna fishing in Kauai aboard the Emma Nalani, our 41-foot Bertram six-pack sport fishing yacht running out of Nawiliwili Small Boat Harbor. Yellowfin Tuna, known in Hawaii by its Hawaiian name "Ahi," is one of the most prized game fish in the Pacific — a hard-fighting, schooling, table-grade species that built Hawaiian commercial fishing and still dominates restaurant menus across the islands.

Ahi tuna fishing in Kauai is world-class because the deep water is right off our coast, with the ocean floor dropping a thousand feet just a quarter mile from the Emma Nalani's slip, and the ledges a mile offshore being prime Ahi country on every yellowfin tuna charter Kauai we run.

  • Yellowfin Tuna are a schooling, highly migratory pelagic species
  • Kauai catches typically run 30 to 100 lbs, with 100+ lb Ahi not uncommon on longer trips
  • The IGFA all-tackle world record stands at 427 lbs (caught off Cabo San Lucas, Mexico, in 2012)
  • Known for sustained, powerful runs and deep, punishing dives — one of the hardest-fighting fish you can hook
  • Sashimi-grade from the moment they hit the deck, prized by Hawaiian and Japanese culinary tradition
427 lbs world record
Yellowfin fishing in Kauai delivers the full package — hard fights, schooling action, and dinner that rivals any sushi bar in Honolulu. If you're booking a trip with Ahi in mind, you picked the right island.

When and Where to Catch
Yellowfin in Kauai

Kauai tuna fishing produces year-round, but peak season runs late spring through early fall. Summer months are prime, with July and August often delivering the biggest fish — though schoolie Ahi in the 20 to 60 lb range are available year-round on Kauai's offshore water.

🟡
FAD Buoys & Offshore Ledges

Hawaii's network of Fish Aggregating Devices (FADs) concentrates Ahi schools at predictable locations — one of the most reliable ahi-finding tools on the water.

🐦
Under Bird Piles

Frigate birds and shearwaters working bait schools often mark Ahi feeding below. A working bird pile means fish — usually Ahi or mahi underneath.

🌊
The 1,000-Fathom Drop-Off and Deeper

Trophy-class Ahi live in deeper water, accessible on the full-day or custom 10 to 12-hour trip. Smaller Ahi can be caught on any trip length, including the half-day.

Size Follows Trip Length

Smaller Ahi can be caught on any of our trip lengths including the half-day fishing charter — an affordable ahi fishing charter Kauai option. Bigger Yellowfin require longer trips, and if you're chasing the best yellowfin tuna fishing Kauai Hawaii has to offer, a longer run with time to reach deeper structure is the way to go.

How We Fish for Yellowfin
on the Emma Nalani

Yellowfin fishing on the Emma Nalani typically starts with high-speed trolling skirted lures, cedar plugs, and rigged baits at 7 to 9 knots. When a school is located, the crew may switch to live bait fishing with Aku (skipjack tuna) or flying fish, or work the FAD buoys with a combination of trolling and jigging. Once an Ahi is hooked, the fight is on — and it's usually a long one.

Ahi don't jump like mahi or sailfish. They fight deep and hard and long, often sounding 200 to 500 feet down and refusing to quit. Landing a big Ahi takes stamina, technique, and a crew that knows how to work the fish from the fighting chair.

  • Heavy trolling rods with Penn International Gold 2-speed reels, rigged with 80 to 130 lb line for trophy-class fish
  • Skirted lures, cedar plugs, and Blue Water rods matched to the conditions
  • Live bait rigs for targeting stationary schools under birds or FADs
  • Big-game fighting chair for landing 100+ lb Ahi from the Emma Nalani's back deck

That's exactly where the Emma Nalani and our captain and crew earn the tip. Every one of our longer charters is set up specifically to handle trophy-class Yellowfin from hook-set to the deck.
