Big Island Offshore Charter: Marlin & Tuna Action
When you're ready to experience some of Hawaii's best offshore fishing, Captain Jim and the Konadice Sportfishing crew have you covered. This 4-hour charter targets the Big Island's legendary blue water species—Blue Marlin, Yellowfin Tuna, and Mahi Mahi—in waters that consistently produce trophy fish. Whether you're an experienced angler or picking up a rod for the first time, this half-day adventure puts you right in the action without eating up your entire vacation day. The flexible scheduling means you can choose morning, midday, or afternoon departures to fit your island itinerary perfectly.
What to Expect on the Water
You'll be fishing the productive offshore waters just outside Kailua-Kona, where the ocean drops off quickly into deep blue territory that pelagic species call home. The boat is clean, well-maintained, and equipped with everything serious offshore fishing demands—top-tier tackle, fresh bait, and all the gear you'll need to battle whatever decides to hit your line. Captain Jim and his crew know these waters intimately and will put you on the fish using proven techniques and local knowledge that only comes from years of working these specific grounds. The 6-person capacity keeps groups small and personal, so everyone gets plenty of attention and rod time. Just pack your own snacks, drinks, and sunscreen—the crew handles everything else, including cleaning your catch at the end of the trip.
Trolling Techniques & Tackle
Offshore fishing here means trolling—the most effective method for covering water and attracting the fast-moving pelagic species that roam these depths. The crew runs a spread of lures at different distances and depths, creating an enticing presentation that mimics a school of baitfish. You'll be using heavy-duty conventional reels spooled with braided line, paired with sturdy rods built to handle the powerful runs and jumps these fish are famous for. When something hits, the crew will coach you through the fight, helping with technique and boat positioning to give you the best shot at landing your catch. The lures include everything from jet heads and marlin lures to smaller baits that attract Mahi and Wahoo. If conditions are right, they might also deploy live bait or switch to different techniques based on what they're seeing on the fish finder.
Customer Stories
"Captain Jim and Dave made us feel welcome. We tried for big game fish, but didn't get any. We did, however, come back with nearly 100 lbs of skipjack tuna (it makes for excellent poké). Would recommend!" - Evan. "Great trip. Will book with Jim and Konadice again next time" - Chad. "Captain Jim and deckhand sawyer are a very experienced team. They put us on fish right out of the harbor and worked the lines the whole time we were fishing. We caught two Mahi Mahi's, but it would have been a great experience even if we didn't catch anything because they were very informative and helpful the whole trip. I would highly recommend this boat to anyone who is looking for a charter. these guys are a top notch hard working crew who will give you the best experience they can offer!" - Kyle.
Top Catches This Season
Blue Marlin are the crown jewel of Hawaiian offshore fishing, and the waters off Kona are among the best places in the world to hook one. These powerful predators can exceed 400 pounds and are known for their spectacular aerial displays when hooked. Peak season runs from April through October, though they're present year-round. What makes catching a Blue Marlin special isn't just the size—it's the fight. They'll make long, powerful runs and often leap completely out of the water multiple times. The crew practices catch-and-release for these magnificent fish, so you'll get photos and bragging rights while helping preserve the fishery for future generations.
Yellowfin Tuna, locally known as Ahi, are prized both for their fighting ability and their exceptional table quality. These torpedo-shaped speedsters typically range from 20 to 100 pounds in these waters, with larger specimens always possible. They're consistent throughout the year but tend to be more abundant during summer months. When you hook an Ahi, expect a sustained, powerful fight—they don't give up easily and will test both your endurance and your tackle. The meat is perfect for sashimi, poke, or grilling, making them one of the most sought-after catches for visiting anglers.
Mahi Mahi are the most colorful and acrobatic fish you're likely to encounter on this charter. Their brilliant gold, green, and blue colors are stunning when they're brought boatside, and they're famous for their jumping ability when hooked. These fish typically range from 10 to 30 pounds in local waters and are most abundant from spring through fall. They often travel in schools, so when you find one, there are usually more around. Mahi Mahi are also excellent eating, with firm white meat that's perfect for fish tacos or grilling.
Shortbill Spearfish are Hawaii's "other" billfish and provide exciting action for anglers. Smaller than marlin but equally acrobatic, they typically weigh between 20 to 40 pounds and are known for their speed and jumping ability. They're present year-round but more common during certain seasons. Wahoo, known locally as Ono, are among the fastest fish in the ocean and provide lightning-quick strikes and blistering runs. They're excellent table fare and can reach impressive sizes, though most caught here range from 15 to 40 pounds.
