Deep sea fishing charters in Kauai, ranked

Deep sea fishing in Kauai is a blue water story told close to shore. The island’s deep water drops away within a mile or two of the harbor mouth, so the boats troll for Pacific blue marlin, ahi, ono, and mahi mahi without a long run offshore. The fleet is small and almost all private: a handful of six pack boats out of two south shore harbors, Nawiliwili in Lihue and Port Allen in Eleele, with only a few selling a shared seat. This page ranks the Kauai deep sea fishing charters worth booking on our published method, and names the boats it set aside and why.

Two things shape a Kauai trip before you pick a boat. The catch policy varies, since some boats let you keep everything while others split the catch and keep the bigger fish, and the fishing license rule has changed: as of 2025 Hawaii requires a nonresident license for anglers 15 and older, even on a charter. Both are covered below.

What you catch and when

Kauai fishes year round, but the target shifts with the season. The warm water months, roughly March into September, bring the biggest migrations and the best fishing: ahi build from spring and peak from May into September, with the fish over 100 pounds most likely from April into August, and Pacific blue marlin run from about February through September with the largest fish in summer. Mahi mahi and ono are the year round troll fish, better in spring and fall, and the most likely to fill a cooler on an average day. Aku run all year and double as a prime live bait for marlin. The cooler months still fish, with striped marlin and shortbill spearfish through the winter and into spring, so there is no dead season, only a different mix. Marlin are usually tagged and released. Confirm any current rules with Hawaii’s Division of Aquatic Resources before you go.

The boats and operators

Kauai’s fleet is small private boats, not a party boat port. There are no head boats selling dozens of seats here; the standard is a six pack charter booked whole, from a 32 foot Blackfin up to a 47 foot Buddy Davis. The boats split between two harbors. Nawiliwili, in Lihue on the east side, is the larger fleet and the one most visitors reach, minutes from the airport and the Kalapaki hotels. Port Allen, in Eleele on the leeward south side, is about 40 minutes west, often calmer and drier when the trades are up, and quick to deep water. A few operators, Makai, Captain Don’s, and Breakaway, sell a shared seat for anglers who do not want to book the whole boat, which is the cheapest way offshore on an island with no party boats. Two practical points apply to every boat: anglers 15 and older now need a Hawaii nonresident fishing license, and the keep your catch policy differs from boat to boat, so ask before you book.

How the field ranks

The field sorts into a clear order, with the gap between the boats coming down to the captain, the comfort, and how plainly each one prices and shares the catch. At the top is Makai Sportfishing at 8.3, the most complete operation on the island, a 45 foot Uniflite out of Port Allen under a third generation owner captain and the rare boat that offers a shared seat, a deluxe trip, and a private charter at posted prices, marked down only for a 1978 hull and the crowding of a full shared boat. Captain Don’s Sportfishing is second at 8.0, the most established Nawiliwili boat with the deepest, warmest review trail on Kauai and a friendly shared or private trip, held back by a working hull without a cabin and a policy that keeps fish over 25 pounds. Imua Fishing Charters takes 7.9, the most comfortable mid size boat, a 37 foot air conditioned Cabo with a high catch rate and a keep your catch policy, limited by a top end price and no shared option.

In the middle, Breakaway Fishing Charters at 7.8 is the value pick, a family run 34 foot Radon out of Nawiliwili with the clearest posted prices in the port, shared, private, and even a spectator seat, on a plain working boat. Apex Kauai Sport Fishing follows at 7.7, the biggest and most comfortable boat on the island, a 47 foot Buddy Davis with an air conditioned salon and the license included, held mid pack by the steepest price in the fleet and private only, longer trips. Below them, Extreme Sportfishing at 7.1 is the no frills veteran option, a classic 35 foot Bertram under a 25 year captain with a keep your catch policy, on an old, slow hull with the lowest rating in the ranked field. Captain Jude’s Deep Sea Fishing Kauai rounds out the list at 7.0, the longest running south side boat under Captain Jude since 2002, strong on the water but dropped to the foot of the field by a recurring overbooking and crowding complaint on a smaller boat. The cards below carry each boat’s verdict and score.

Trip types and what they cost

Kauai fishes two ways. The cheaper route is a shared seat, which Makai, Captain Don’s, and Breakaway sell from about $190 to $215 per person for a 4 hour trip, putting you on a boat with other anglers and splitting the cost. The standard route is a private charter, the whole boat for your group of up to six: roughly $825 to $1,200 for a half day and $1,600 to $2,600 for a full day, climbing with the size and comfort of the boat, from Extreme’s working Bertram to the luxury Apex. Gear and catch cleaning are included on every boat. The two things to budget and check beyond the sticker are the Hawaii nonresident license, about $20 a day unless the boat includes it as Apex does, and the catch policy, since some boats keep the bigger fish. Our cost guide breaks the tiers down, and the shared versus private charter guide helps you choose the format, which is the biggest decision you make on Kauai.

How to pick the right trip

Start with your group and your budget. A solo angler or a couple watching the cost should take a shared seat with Makai, Captain Don’s, or Breakaway, the only boats here that sell one. A group of four to six is better off on a private charter, where the per person cost drops as you fill the boat. If comfort matters, on a hot day or with a queasy stomach, pay up for an air conditioned cabin on Imua or the big, stable Apex; if it does not, Extreme and Captain Don’s fish just as hard for less. For the west side, Makai and Deep Sea Fishing Kauai leave from Port Allen, often the calmer side; the rest run from Nawiliwili near Lihue. And if keeping a big ahi to eat is the point, book a boat that lets you keep your catch and confirm it first. The first time guide covers the rest of the prep.

Getting there and what to bring

Kauai’s two charter harbors sit on the south and east of the island. Nawiliwili Small Boat Harbor is in Lihue, a few minutes from the airport and the Kalapaki hotels, and hosts most of the fleet. Port Allen Small Boat Harbor is in Eleele, about 40 minutes west, and is the leeward, often calmer side. Trips leave early, many at 6 a.m. or before, so plan the drive and arrive 30 to 45 minutes ahead to park and find the boat. Buy your Hawaii nonresident fishing license online before the trip, since anglers 15 and older now need one and most boats do not supply it. Bring reef safe sunscreen, a hat and polarized sunglasses, a light jacket for the run out, food and drinks, and motion sickness medication if you are unsure of your stomach, since Kauai’s deep water and the trade wind chop sit close to shore. A cooler is worth having for whatever catch you take home.

Kauai is the northwestern end of the Hawaiian island chain we cover. Kona on the Big Island is the marlin capital and the islands’ marquee port, and the Hawaii hub ranks the boats on each island on the same standard.
