Private Offshore Charter: Blue Marlin & Mahi Mahi
When you're serious about offshore fishing and want the waters to yourself, this private full-day charter out of Kailua-Kona delivers exactly what professional anglers are looking for. We're talking about prime Big Island fishing grounds where Blue Marlin cruise the blue water and Mahi Mahi light up in electric colors when they hit your spread. This isn't a cattle boat operation – it's your boat, your crew, and your shot at the fish that make Kona famous worldwide. With room for up to six anglers, you'll have plenty of space to work the rods without bumping elbows, and the captain's undivided attention on putting you on fish.
What to Expect on the Water
Your day starts early at Honokohau Harbor, where you'll meet your captain and get the rundown on conditions, tackle, and game plan. The boat heads out into some of the deepest, clearest water you'll find anywhere – we're talking 1,000+ foot depths just a few miles from shore. That's what makes Kona special for big game fishing. The continental shelf drops off fast here, bringing pelagic species right to your doorstep. Your spread will typically include a mix of lures and natural baits, with the captain adjusting based on what's been working and current conditions. Between the serious fishing action, there's an optional stop at Kealakekua Bay for snorkeling if the group wants a change of pace. Just remember you'll need a non-resident marine fishing license – grab it online before your trip. There's also a potential $100 fuel surcharge depending on current fuel costs, but your captain will let you know upfront.
Trolling Tactics & Gear Setup
This charter runs a professional spread designed to attract multiple species at once. We're talking heavy tackle – 50 and 80-pound class outfits that can handle whatever comes up from the depths. The boat trolls a variety of lures including cedar plugs, jet heads, and skirted trolling lures in colors that work in Kona's gin-clear water. The captain will adjust trolling speed based on target species – slower for marlin, faster when mahi mahi are the focus. Outriggers spread the lines wide to avoid tangles and create a natural bait school appearance. When fish are located, the boat may switch to live bait fishing with opelu or other local baitfish. All tackle, lures, and rigging are included, though serious anglers often bring their favorite rods if they have preferences. The crew handles all the technical stuff like setting the drag, gaffing, and boat positioning during fights.
Top Catches This Season
Blue Marlin remain the crown jewel of Kona fishing, and these waters consistently produce some of the largest Pacific Blue Marlin caught anywhere. These apex predators can show up any time of year, but late spring through fall tends to be most productive. A 200-300 pound blue marlin will test your endurance and technique, often jumping repeatedly and making long, powerful runs. What makes catching one here special is the crystal-clear water – you can actually watch the fish work during the fight. Mahi Mahi provide fast action and incredible table fare, typically running 10-40 pounds in these waters. They're aggressive feeders that often travel in schools, so when you find one, there are usually more around. Yellowfin Tuna are pure muscle, fighting straight down with bulldogging power that will burn your arms. These fish are prized for sashimi and can reach 100+ pounds in Kona waters. Striped Marlin offer aerial displays that rival blue marlin but in a smaller, more manageable package. Shortbill Spearfish are the speedsters of the billfish family, making blistering runs and providing excellent light tackle action.
Species You'll Want to Hook
Blue Marlin are the ultimate prize fish, with Kona waters producing fish over 1,000 pounds. These magnificent billfish are most active during warmer months but can be caught year-round. They're ambush predators that cruise the edge of the thermocline, often following schools of baitfish. The fight is legendary – expect multiple jumps, long runs, and a battle that can last hours. Most anglers practice catch and release with these magnificent fish. Mahi Mahi are the workhorses of offshore fishing here, providing consistent action and fantastic eating. They're drawn to floating debris, weed lines, and temperature breaks. These fish light up in brilliant golds and greens when excited, putting on a visual show during the fight. Peak season runs from spring through fall, with fish ranging from small school-size dolphins to large bulls over 50 pounds.
Yellowfin Tuna are built for speed and endurance, making them one of the most challenging fish to land. In Kona waters, they typically run 40-150 pounds and are found around schools of porpoise or working bird flocks. They fight deep, using their powerful tail and streamlined body to maintain constant pressure. The meat is premium grade, making them highly sought after. Striped Marlin are smaller cousins to blue marlin but equally spectacular fighters. They're most common during winter months and provide incredible aerial shows. These fish typically range 80-150 pounds and are known for their intelligence and wariness. Shortbill Spearfish are the smallest billfish you'll encounter, but don't underestimate them. They're incredibly fast and acrobatic, often clearing the water multiple times during a fight. They're excellent on lighter tackle and provide great action when larger fish aren't cooperating.
