Private fishing charter accommodates up to 3 guests comfortablyTarget Mahi Mahi, Tuna, and Marlin in Kauai watersFlexible 4 to 8-hour trips starting at 6:00 AM
Looking for a fishing charter that puts you in control? Our private Kauai fishing trips let you call the shots – from 4 hours of pure action to a full 8-hour battle with the big ones. Captain Blue Water Fishing LLC runs these trips on a solid 26-foot Glacier Bay that handles Kauai's offshore waters like a dream. With twin 150hp engines pushing us along, we'll get you to the fish fast and keep you comfortable while you're working the lines. Space is limited to just 3 guests, so you're not fighting for rod time or elbow room.
We push off at 6 AM sharp when the water's still calm and the fish are waking up hungry. The Glacier Bay cuts through the swells smooth as butter, so even if you're prone to seasickness, you'll be surprised how stable she feels. Kauai's offshore fishing grounds are legendary – we're talking deep blue water that drops off the continental shelf just miles from shore. That's where the big pelagics cruise, and that's exactly where we're headed. The boat's rigged with quality tackle and outriggers, plus all the terminal gear you'll need. Whether you're a weekend warrior or you've been chasing billfish for decades, we've got setups that match your skill level. The shorter 4-hour trips focus on the closer grounds where mahi mahi and smaller tuna hang out, while the 8-hour journeys take us to the deep water where marlin patrol.
We run a spread of 4-6 lines depending on conditions, mixing lures and live bait to cover all the bases. The outriggers let us spread our pattern wide, and we'll adjust our trolling speed based on what we're targeting. For mahi mahi, we'll pull colorful skirted lures at 6-8 knots through current lines and debris fields where they love to hang. When we're marlin hunting, it's all about covering water with bigger baits and watching for birds or temperature breaks. The Glacier Bay's fish finder helps us locate bait schools and structure, but honestly, reading the water and watching for signs is half the fun. We carry spinning gear too for when the bite gets technical or when we want to cast at surface feeders. All tackle is included, from 30-pound setups for smaller fish up to 80-pound gear for the monsters. If you've got lucky lures or specific tackle you trust, bring them along – we love seeing what works for different anglers.
Blue Marlin are the kings of Kauai's offshore waters, and hooking one will ruin you for other fish forever. These beasts average 200-400 pounds around here, with occasional giants pushing 600-plus. Summer months from May through September give you the best shot, when the water's warmest and baitfish are thick. Blues are notorious for their aerial displays – watching a 300-pound fish launch itself 10 feet out of the water is something you'll never forget. They're also the reason we carry heavy tackle and keep our drag systems tuned perfectly.
Mahi Mahi might be the most fun fish in the ocean, pound for pound. These golden beauties hit hard, jump high, and taste even better. They school up around floating debris, current lines, and temperature breaks, usually in 1,000-3,000 feet of water. Bulls can hit 40-50 pounds, while cows typically run 10-25 pounds. What makes mahi special is their willingness to bite – when you find a school, you can often catch several before they wise up. They're most active during spring and summer, but we see them year-round in Hawaiian waters.
Wahoo are the speed demons of the deep, capable of stripping 200 yards of line in seconds. These silver missiles prefer the deeper, clearer water and are notorious for cutting lines with their razor-sharp teeth. That's why we run wire leaders when targeting them specifically. Wahoo average 20-40 pounds around Kauai, with occasional fish pushing 60-plus. They hit trolled lures hard and fast, often when you least expect it. Fall and winter months tend to be best for wahoo, when the water cools slightly and they move in closer to the islands.
Yellowfin Tuna are pure muscle wrapped in a torpedo shape. These fish fight dirty – long, powerful runs followed by dogged battles in the depths. Around Kauai, yellowfin range from 40-pound schoolies up to 200-pound giants that'll test every knot and connection. They're most active around dawn and dusk, which is why our early start time is so important. Yellowfin travel in schools and follow bait, so when we mark them on the sounder, it's game time. They hit both lures and live bait, and they're fantastic eating if you want to keep one for the table.
Striped Marlin might not be as big as their blue cousins, but they make up for it with acrobatics and attitude. These fish love to jump, often clearing the water multiple times during a fight. They typically run 80-150 pounds in Hawaiian waters and are more common during winter months when the water cools. Striped marlin are also more likely to bite lighter tackle, making them perfect for anglers who want the billfish experience without needing a back brace afterward.
This is exactly the kind of fishing that keeps people coming back to Kauai year after year. With only 3 spots available per trip, you're getting a private charter experience without the private charter price tag. The flexibility to choose your trip length means you can match the adventure to your schedule and budget. Whether you book the 4-hour trip for a taste of Kauai's fishing or go
Hit the deep waters around Kauai aboard our 26-foot Glacier Bay Catamaran, built to get you to the fish fast and keep you comfortable all day. Twin 150hp Suzuki engines push this cat to 30 knots, cutting through swells to reach prime fishing grounds where Mahi Mahi, Tuna, and Marlin cruise the blue water. The stable catamaran design means less rolling when you're fighting fish, while our GPS and fish finder help locate the action. With room for up to 4 anglers, you'll have plenty of space to work your lines without crowding. The onboard facilities keep everyone comfortable during those longer 8-hour runs to the deep drop-offs. Whether you're targeting pelagics on the troll or dropping baits in the depths, this Glacier Bay delivers the speed and stability serious anglers need in Kauai's challenging offshore waters.
Makaira NigricansBlue marlin are the apex predators we chase in Hawaiian waters, and for good reason. These giants average 200-400 pounds, but females can hit over 1,000 pounds - we call those "granders." They cruise the open ocean hunting tuna and smaller fish, using that signature bill to stun prey. You'll find them in deep blue water, usually 100+ fathoms, following current breaks and temperature changes. Best action happens April through October when water temps climb. What makes them special? That first jump when hooked - pure power and acrobatics that'll test your gear and your heart. The meat's decent but catch-and-release is preferred for these breeding females. Pro tip: when trolling, keep your lures skipping on the surface - blue marlin love to come up and smash baits from below, especially around midday when they're most active.
Coryphaena HippurusMahi mahi are hands down the most colorful fish you'll catch out here - bright gold sides with electric blue and green that put on a light show when they come aboard. These fast-growing fish typically run 15-30 pounds, though we see some pushing 50. They love hanging under floating debris, weed lines, and current edges in that beautiful blue water. Year-round fishing here, but summer months are prime time when they're thick. What guests love most? They're aggressive fighters that jump and make long runs, plus they're absolutely delicious - sweet, firm white meat that's perfect for fish tacos. Often travel in small schools, so when you hook one, keep the lines out. Local secret: once you find floating sargassum or debris, work it thoroughly with small jigs and live bait - mahi will hold tight to structure and the whole school will usually bite.
Kajikia AudaxStriped marlin are the most beautiful billfish we target - lighter blue than their cousins with distinct pale stripes that stay visible even after the fight. These fish typically run 100-300 pounds with a more slender build than blue marlin. They prefer surface waters along drop-offs and current breaks, often "tailing" on calm days. Best fishing happens during our winter months, December through April, when they migrate through Hawaiian waters. Guests love them because they're incredible jumpers and acrobats - probably the most aerial of all billfish. The meat's excellent too, similar to swordfish but with more flavor. They're aggressive feeders that will chase down tuna and smaller pelagics. Pro tip: watch for birds working bait schools and keep your eyes peeled for those distinctive dorsal and tail fins cutting the surface. When you spot one, get a live bait in front of it quickly - they're opportunistic hunters.
Acanthocybium SolandriWahoo are the speed demons of our waters, hitting 50+ mph with razor-sharp teeth that'll slice through your leader in a heartbeat. These sleek, torpedo-shaped fish average 20-40 pounds but can push 80. They roam open ocean waters, usually solo or in small groups around drop-offs and current edges. Peak season runs May through October when water temps are warm. What makes them special? That initial run is lightning fast and they fight dirty - sudden direction changes that test your drag. The meat is premium - white, flaky, and mild, known locally as "ono" which means delicious in Hawaiian. Wahoo are picky, so high-speed trolling at 12-15 knots works best with wire leaders - mono won't survive their teeth. Key tip: when you see diving birds working bait schools, that's prime wahoo water. Troll the edges fast with smaller lures and hold on tight when they hit.
Thunnus AlbacaresYellowfin tuna are the workhorses of our offshore fishing - powerful, fast, and built like torpedoes. Most fish we catch run 40-100 pounds, though bigger ones push 200+. They school in deep blue water, usually 100-300 feet down, following bait and current edges. Fishing's good year-round but peaks in summer when they move closer to shore. Guests love them because they fight straight down with incredible power - it's a test of endurance between you and the fish. Plus, the meat is world-class sashimi grade when handled right. These fish are smart and can be picky, so we mix up techniques from trolling to chunking to vertical jigging. Best local trick: when nothing's biting on the surface, drop jigs straight down into the school. They'll often hit jigs when they won't touch trolled baits, especially during midday when they go deep.
