Private Trip
Offshore Fishing
8-hour offshore charter targets marlin, mahi, wahoo, and spearfishCaptain Gaige guides groups of up to 6 passengersPremium Kona waters offer exceptional deep-sea fishing opportunities
Captain Gaige and the crew at Kona Cowboy Sportfishing know exactly where the big fish are biting off the Kona Coast. This full-day offshore charter takes you into some of Hawaii's most productive blue water, where marlin patrol the drop-offs and mahi mahi cruise the current lines. With just six anglers max, you'll have plenty of room to fight fish and won't be elbow-to-elbow with a crowd when the action heats up. Eight hours gives you serious time to work the grounds, from the morning bite through the afternoon pickup when the wahoo start moving.
You'll meet Captain Gaige at the harbor before dawn, when the coffee's strong and the anticipation's running high. The boat's rigged and ready with fresh bait and sharp hooks – all you need to bring is your fishing license, sunscreen, and maybe some snacks since meals aren't included. We'll steam out to the prime fishing grounds where the deep blue water holds everything from 100-pound marlin to screaming wahoo. The Kona Coast is famous for its close-to-shore drop-offs, meaning you're not burning half the day just getting to where the fish live. Within 30 minutes, you'll be setting lines in water that's over 1,000 feet deep, watching the outriggers work as we troll the productive zones where baitfish concentrate and predators follow.
This is classic offshore trolling at its finest. Captain Gaige runs a spread of lures designed to attract different species – big marlin lures that create a bubble trail, smaller high-speed lures for wahoo, and everything in between for mahi and spearfish. The boat's equipped with quality rods and reels that can handle whatever decides to eat, from 30-pound class tackle for the smaller stuff up to heavy gear when we're targeting big marlin. You'll learn to read the water, watching for color changes, current lines, and bird activity that signal where the fish are holding. When something hits, the captain will coach you through the fight – whether it's keeping pressure on a jumping marlin or cranking hard on a deep-diving wahoo. The deck layout gives every angler room to move, and with only six people aboard, you're not fighting for space when multiple fish hit the spread.
Blue Marlin are the kings of these waters, and Kona's famous for producing some true giants. These apex predators can show up any time of year, but summer months typically see the biggest fish moving through. When a blue marlin eats your lure, you'll know it – the rod bends, the reel screams, and often the fish comes completely out of the water in a spectacular display. They're powerful, stubborn fighters that test your endurance and the captain's boat-handling skills. Most blues here run 100 to 300 pounds, but fish over 500 pounds cruise these waters, making every hookup a potential fish of a lifetime.
Mahi Mahi, or common dolphinfish, are the workhorses of the Kona fishing scene. These beautiful, golden fish travel in schools and provide consistent action when conditions are right. They're incredibly acrobatic fighters, jumping and tail-walking across the surface while showing off their brilliant colors. Mahi typically run 10 to 40 pounds here, with occasional bulls pushing 50-plus. They're excellent eating and perfect for anglers who want steady action. Look for them around floating debris, current lines, or anywhere baitfish are schooling near the surface.
Longbill Spearfish are often called the "poor man's marlin," but don't let that fool you – these fish are serious fighters with serious bills. They're smaller than their marlin cousins, usually running 20 to 60 pounds, but they make up for size with attitude. Spearfish are common in Kona waters year-round and provide excellent light-tackle action. They jump, they run, and they'll give you a workout on appropriate gear. Many anglers prefer them to larger billfish because you can actually enjoy the fight without wondering if you'll be able to walk tomorrow.
Wahoo are the speed demons of the offshore world, capable of hitting 60 mph and stripping line faster than you can blink. These torpedo-shaped predators hit lures with incredible violence, often cutting through leaders with their razor-sharp teeth. In Kona waters, wahoo typically range from 15 to 60 pounds, with the occasional monster pushing 80-plus. They're fantastic eating – firm, white meat that's perfect for the grill. Wahoo fishing is often best early morning or late afternoon, and when they're biting, the action can be non-stop.
Striped Marlin are the acrobats of the billfish world, known for their incredible jumping ability and beautiful purple stripes that light up when they're excited. These fish are smaller than blues, typically running 80 to 150 pounds in Hawaiian waters, but they make up for it with spectacular fights above the surface. Striped marlin are often more cooperative than their blue marlin cousins, making them perfect for anglers who want a legitimate billfish experience without the marathon battles that big blues can deliver.
This charter books up fast, especially during peak fishing season when the bite is hot and word spreads quickly through the local fishing community. Captain Gaige has built a solid reputation for putting clients on fish and making sure everyone has a great time on the water. The 8-hour format gives you maximum fishing time without feeling rushed, and the 6-person limit ensures you get personal attention when you hook up. Whether you're a seasoned angler looking for your next trophy or a newcomer wanting to experience world-class offshore fishing, this charter delivers the goods. Book
Set sail aboard the Kona Cowboy, a legendary 1968 Merritt sportfishing vessel that's been prowling Kona's blue waters for decades. This classic beauty packs serious punch with twin Cummins 480HP engines that'll get you to the fishing grounds fast, cruising at 28 knots to maximize your time chasing marlin, mahi, and wahoo. Captain Gaige knows these waters like the back of his hand, and with the boat's fish finder and GPS, you'll be positioned over the best structure where the big fish hunt. The flybridge gives you commanding views of the action, perfect for spotting that telltale splash or watching your lines. Keep your catch fresh in the onboard icebox while you target everything from blue marlin to spearfish in Kona's world-class offshore waters. With room for up to 6 anglers, there's plenty of space to work the rods without getting tangled up during the fight of a lifetime.
Makaira NigricansBlue marlin are the giants of the billfish world - females can hit 1,000+ pounds (we call those "granders"), while males stay around 300. They cruise Kona's deep blue waters year-round, usually solo, hunting tuna and other pelagics. You'll find them in 1,000+ feet of water along drop-offs and current breaks. Peak season runs April through October when water temps are warmest. What makes them special? That explosive power and those aerial shows - they'll leap completely out of the water multiple times. The fight can last hours. Here's a local tip: when you see one "lit up" (that electric blue color when they're excited), get ready - they're about to strike. Use heavy tackle and be patient.
Tetrapturus PfluegeriLongbill spearfish are the rare gems of our waters - smaller billfish running 20-40 pounds and 4-6 feet long. They're built slender with that classic spear bill, dark navy backs, and silver bellies. You'll encounter them in deep offshore waters following tuna schools or squid concentrations. They're uncommon catches, which makes landing one special. These fish are strictly catch-and-release due to their low numbers. They put up a solid fight with some jumps, but nowhere near the power of marlin. Peak encounters happen during warmer months when baitfish are abundant. Local tip: if you hook one, don't boat it - keep it in the water, calm it down, then either remove the hook carefully or cut the line. They're too rare to risk injury.
Coryphaena HippurusMahi mahi are pure eye candy - brilliant gold sides with electric blues and greens that put on a light show when hooked. They average 15-30 pounds but can hit 50+. You'll find schools around floating debris, weedlines, and current edges in 300-2,000 feet of water. They're here year-round but peak May through September. Guests love them because they fight hard with lots of jumps, plus they're fantastic eating - white, flaky meat that's perfect grilled or in fish tacos. They mature fast and reproduce heavily, so they're sustainable too. Pro tip: when you hook one, leave it in the water briefly - the splashing often brings the whole school up, and you can catch multiple fish on different lines.
Kajikia AudaxStriped marlin are the most beautiful billfish you'll see - lighter blue than their cousins with distinctive pale stripes that stay visible even after the fight. They run 200-400 pounds on average with that classic torpedo shape built for speed. You'll find them in deep water beyond 1,000 feet, usually hunting schools of tuna and smaller pelagics. Best action happens during our winter months, December through April. What sets them apart is their aggressive nature and spectacular jumps - they'll tail-walk across the surface like they're showing off. The meat makes excellent sashimi too. Local strategy: watch for bird activity over bait schools. When you see diving seabirds, there's often striped marlin working underneath, slashing through the baitfish.
Acanthocybium SolandriWahoo are the speed demons of the deep - capable of 60 mph bursts that'll scream line off your reel. They average 20-50 pounds with torpedo-shaped bodies, razor teeth, and distinctive blue zebra stripes. You'll find them in open water from 200-2,000 feet, often around drop-offs and current breaks. Peak season here runs May through October. Guests love the blistering runs and the fact they're phenomenal table fare - firm white meat that's sweet and mild. We call them "ono" in Hawaii, meaning delicious. The key is speed trolling at 12-15 knots with wire leaders since their teeth will slice mono instantly. Local trick: use a plunger-style lure in blue and white - something about that combination drives them crazy.
