12hour deep sea charter targets trophy Bluefin Tuna offshoreVenture to San Clemente Island or Mexican waters for active fishSmall group charter accommodates up to 5 guests maximum
When you're serious about landing trophy bluefin tuna in San Diego waters, this 12-hour deep sea charter is where the real action happens. We're talking about heading way offshore – either to San Clemente Island or into Mexican waters – wherever the fish are showing up on the meter and feeding hard. This isn't your typical half-day trip; we're chasing world-class bluefin that can tip the scales at 200+ pounds, and we'll stay on them until the sun goes down.
Your day kicks off with a late morning departure, which works perfectly since bluefin are notorious for turning on during those afternoon hours when the water temperature shifts and baitfish start moving. We'll run hard to the zones where these pelagic giants are holding, sometimes 20-30 miles offshore where the water turns that deep blue color every angler dreams about. The boat holds up to 5 anglers max, so you're getting personalized attention and plenty of elbow room when that 60-pound bluefin comes screaming toward the boat. Plan on being out there 12-15 hours total – we leave when the fish tell us to leave, not when the clock says so. Pack layers because it gets chilly once that sun drops, and bring your own food and drinks since meals aren't included on this charter.
We're running a combination of techniques depending on what the tuna want that day. Live bait fishing with sardines or mackerel is our bread and butter – there's nothing like watching a 150-pound bluefin explode on a perfectly presented live sardine 40 feet behind the boat. When they're deeper, we'll drop heavy jigs and work the water column until we find where they're stacked up. The captain provides all the heavy tackle you'll need, including those big conventional reels spooled with 60-80 pound test that can handle these freight trains. If you've got your own gear, bring rods rated for 40-80 pound line – anything lighter and you'll be fighting fish all day without landing them. We'll also be ready to switch to surface iron or poppers if we find schools of yellowfin or skipjack mixed in with the bluefin. The key out here is being versatile and reading the water conditions as they change throughout the day.
Bluefin tuna are the main event on this charter, and San Diego's waters have been producing some absolute monsters. These fish are pure muscle and attitude – when you hook into a 100-pounder, it's going to test every bit of your stamina and drag system. They'll make long runs, dive deep, and circle under the boat trying to break you off on anything they can find. What makes bluefin special is their fighting style; they don't give up easily and they use their size and speed to their advantage. Best fishing happens from late spring through fall, with peak action in summer when water temperatures hit that sweet spot around 65-70 degrees.
Yellowfin tuna show up regularly on these offshore runs, especially when we're working the edges of underwater structure near San Clemente Island. They're typically smaller than bluefin but pound-for-pound some of the strongest fish in the ocean. Yellowfin love to school up and when you find one, you'll usually find more. They're also excellent eating, with that bright red meat that's perfect for sashimi.
Mahi mahi, or dorado as we call them locally, are the wildcard species that can make your day even more exciting. These fish are absolute acrobats – they'll jump, tail-walk, and put on a show that'll have everyone on the boat grabbing their phones. They typically show up around floating kelp paddies or debris lines where small baitfish congregate. Mahi are also some of the best eating fish in the ocean, with white, flaky meat that's perfect on the grill.
Yellowtail amberjack are another favorite target, especially around San Clemente Island's rocky structure. These fish are known for their incredible runs and their ability to find every rock and kelp strand to break your line on. They're year-round residents but fishing is best in spring and fall when they're feeding aggressively. Yellowtail are also prized for their firm, white meat that's versatile in the kitchen.
Skipjack tuna might be the smallest species we target, but they make up for size with sheer numbers and fight. When we find a school of skipjack, it's non-stop action with multiple hookups and bent rods everywhere. They're perfect for anglers who want constant action and great practice for handling larger tuna species.

Your pursuit of trophy Bluefin Tuna starts aboard our well-equipped 32' Boston Whaler 305 Conquest. This reliable motor yacht cuts through San Diego waters with twin 250HP Mercury Verados, cruising comfortably at 30 knots toward San Clemente Island or Mexican fishing grounds where the big fish are biting. The spacious layout accommodates up to 5 anglers with all the essentials for your 12-hour deep sea adventure - fish finder and radar to locate schools, GPS for precise navigation, plus onboard kitchen, refrigerator, and AC to keep you comfortable during those long afternoon Bluefin runs. When the bite slows, grab some rest on the bed or use the head facilities. We'll chase these powerful pelagic species from late morning until after dark, targeting their prime afternoon feeding times in deep offshore waters.
Thunnus ThynnusThe holy grail of our long-range trips. These monsters average 130 pounds but can reach 400+ pounds in our local waters. They're the strongest fish in the ocean - built like torpedoes with incredible stamina. We find them around San Clemente Island and down into Mexican waters, usually in 100-1000 feet of water. Late afternoon into evening offers the best bite windows. What makes bluefin special? The fight of a lifetime and meat that's worth its weight in gold - literally. This is sushi-grade tuna at its finest. Here's the deal: when you hook a bluefin, settle in for the long haul. Use a fighting belt, stay calm, and pump and wind. Don't try to horse them up - they'll just dive deeper and wear you out faster.
Coryphaena HippurusThese golden beauties are what dreams are made of - brilliant colors that shift from blue-green to electric yellow as they fight. Most mahi run 15-29 pounds, but we see some pushing 40+ pounds during peak season. They love floating debris and kelp lines, usually in the top 100 feet of water. Summer through fall brings the best action when water temps climb. What makes them special? That lightning-fast surface fight and incredible table fare - firm, white meat that's perfect grilled or pan-seared. Pro tip: when you hook one, keep your eyes peeled for others - they travel in schools and seeing one means there's likely more around. The colors alone make this fish worth the trip, but the fight and flavor seal the deal.
Katsuwonus PelamisThe scrappy little cousins of the tuna family, skipjack average 20 pounds and rarely exceed 30. They're easily spotted by those dark vertical stripes on their silver sides. These guys school up in huge numbers in the upper water column, often mixed with juvenile yellowfin. They're around year-round but peak in warmer months. What's great about skipjack? They're willing biters and put up a solid fight for their size. Plus, they make excellent live bait for bigger tuna and billfish. They're also the main fish in most canned tuna. Pro tip: when you find a skipjack school, work it fast with small feathers or hoochies trolled at 4-6 knots. They spook easily, so circle wide and let your baits drift through the school rather than driving right through it.
Thunnus AlbacaresYellowfin are the workhorses of our long-range trips, averaging 60 pounds with some reaching well over 100. These torpedo-shaped fish cruise the upper water column year-round in our offshore waters. Their speed is incredible - up to 50 mph - making for heart-pounding fights. What anglers appreciate is their consistency and excellent meat quality, second only to bluefin for sashimi. They school up and can be targeted with trolling, jigging, or live bait. The key is watching for birds working bait balls - that's where you'll find feeding yellowfin. Local tip: when nothing's biting on the troll, switch to the jig. Drop it deep and work it fast through the school. That erratic action often triggers strikes when they're being finicky.
Seriola LalandiSan Clemente and Catalina Islands hold some of the best yellowtail fishing you'll find anywhere. These fish average 15-25 pounds but can push 40+ if you're lucky. They're strong, fast swimmers that'll test your tackle around kelp beds and rocky structure. Summer brings the best fishing when warm water moves in. What guests love most is the raw power - yellowtail don't give up easy and will make long runs toward structure. Plus, they're fantastic eating, especially popular for sushi. Here's a local trick: when you hook one, don't muscle it too hard early on. Let it make its first run, then apply steady pressure. Try to keep it away from the kelp, or it'll wrap you up every time.
