Premium Kona Fishing: 10-Hour Deep-Sea Adventure

Full-Day Offshore Fishing Charter in Kailua-Kona

When you're looking for world-class deep sea fishing, the waters off Kailua-Kona deliver like nowhere else on earth. This 10-hour offshore charter with Konadice Sportfishing puts you right in the heart of Hawaii's most productive big game fishing grounds. We're talking about waters where thousand-pound Blue Marlin cruise the drop-offs, massive Yellowfin Tuna patrol the seamounts, and colorful Mahi Mahi light up the surface around floating debris. Whether you've been fishing your whole life or you're picking up a rod for the first time, our professional crew will put you on fish and make sure you have the skills to land them. You'll need to bring your own food, drinks, and sunscreen – we've got everything else covered, from top-shelf tackle to the local knowledge that makes all the difference out there.

What to Expect on the Water

This isn't your typical half-day trip where you're rushing back to the dock just as the bite heats up. With 10 hours on the water, we have the luxury of time to work the prime fishing zones properly. We'll start the day running out to the deep blue, where the ocean floor drops from 600 feet to over 6,000 feet in less than two miles. That dramatic underwater topography creates the perfect conditions for baitfish, and where you find bait, you find the predators. The boat accommodates up to 6 anglers, which means everyone gets plenty of room to fish and personalized attention from the crew. We'll spend our time trolling the productive waters between 1,000 and 3,000 feet deep, adjusting our techniques based on what we're seeing on the fish finder and what's been producing lately. The beauty of a full day is that we can cover a lot of water and adapt to changing conditions – if the morning bite is slow, we've got all afternoon to find where the fish are holding.

Trolling Techniques & Gear

We run a spread of lures designed to attract different species at various depths. The outriggers carry our marlin lures – usually 8 to 12-inch skirted heads in colors that have been producing. Inside those, we'll run smaller lures for Mahi Mahi and Wahoo, often with a mix of artificials and natural baits like flying fish or small Ono. The center lines typically carry our tuna gear, with cedar plugs or feathers that dive deeper in the water column. All our reels are spooled with heavy line – usually 80 to 130-pound test – because you never know when a giant is going to grab your bait. The rods are matched to the technique, from lighter outfits for Mahi Mahi up to heavy-duty marlin sticks that can handle fish over 500 pounds. Don't worry if you've never used this kind of gear before – our crew will coach you through everything from setting the hook to fighting the fish. We've taught thousands of anglers over the years, and there's nothing better than watching someone land their first big Pacific fish.

Top Catches This Season

The Blue Marlin around Kona are legendary for good reason – these waters consistently produce some of the largest marlin caught anywhere in the Pacific. Peak season runs from May through September, but we see fish year-round, with the biggest typically showing up during the summer months. A 200-pound marlin is a nice fish here, 400 pounds gets exciting, and anything over 600 pounds is the fish of a lifetime. They're ambush predators that often hit without warning, turning a peaceful trolling session into controlled chaos in seconds. Yellowfin Tuna, known locally as Ahi, are another customer favorite that can show up any time of year. The fish we catch offshore typically run 40 to 150 pounds, with occasional giants pushing 200-plus. They're incredibly strong fighters that make long runs and test your endurance – landing a big Ahi is as much about technique as it is about muscle.

Mahi Mahi bring the color and acrobatics that make for great photos and even better eating. These fish are most abundant from spring through fall, often traveling in schools around floating debris or kelp mats. They're aggressive feeders that hit lures hard and immediately start jumping, putting on a show that never gets old. A good-sized Mahi Mahi runs 15 to 40 pounds, with the occasional bull pushing 50-plus. Shortbill Spearfish are the sleeper hit of many trips – they're smaller cousins to marlin that jump just as much and fight just as hard pound-for-pound. They're most common during the warmer months and typically range from 20 to 60 pounds. Wahoo are the speed demons of the deep, capable of hitting 50 mph and making blistering runs that can empty a reel in seconds. They show up year-round but are most consistent from fall through spring, usually running 15 to 50 pounds with razor-sharp teeth that can cut through wire leaders.
