12-hour offshore charter targeting premium pelagic speciesProfessional guides pursue tuna, wahoo, sailfish, and marlinEarly 6:30 AM departure accommodates up to 6 guests
Ready to chase some serious gamefish? This isn't your typical half-day bay trip – we're talking about a full 12-hour charter that'll take you way beyond the surf line into the deep blue where the real monsters swim. Starting at 6:30 AM sharp, you'll spend the entire day hunting trophy pelagics in some of the Gulf's most productive waters. With Captain and crew handling the navigation and rigging, your only job is to hold on tight when that reel starts screaming.
This world-class fishing charter targets the offshore waters where Port Aransas really shines. We're not messing around with small stuff here – you'll be trolling for Blackfin Tuna, casting to Mahi schools, and hopefully getting that sailfish bite you've been dreaming about. The boat heads out early to maximize your time in the prime fishing zones, usually 15-30 miles offshore depending on where the bite's been hot. With just 6 anglers max, there's plenty of room to fish without stepping on each other's lines. The crew knows these waters like the back of their hand and they'll put you on fish if they're biting. Bring your own lunch and drinks since meals aren't included – you'll definitely work up an appetite fighting fish all day.
This top-rated charter runs a serious trolling spread designed to cover water and attract multiple species. The crew rigs everything from high-speed wahoo lures to slower-moving sailfish baits, adjusting speeds and depths based on conditions and target species. You'll fish with quality conventional reels spooled with heavy line – usually 30-50 pound test depending on what we're after. When the trolling slows down, we switch to live bait fishing around structure or floating debris where Mahi like to hang out. The captain reads the water constantly, looking for birds, color changes, and bait schools that signal feeding fish below. GPS and fish finder technology help locate productive bottom structure, but experience and local knowledge make the real difference in consistently finding fish.
Mahi Mahi, or Common Dolphinfish as they're officially known, are hands down the most fun fish you'll encounter on this trip. These electric-colored fighters love warm water and floating debris, making Port Aransas waters perfect habitat from late spring through fall. Bulls can push 30-40 pounds and put on an aerial show that'll get your heart pumping. They school up around sargassum patches and any floating objects, so when you find one, there's usually more nearby. What makes Mahi special is their aggressive nature – they'll hit everything from trolled ballyhoo to jigs worked around the boat.
Wahoo are the speed demons of the deep, capable of stripping 100 yards of line in seconds with their blistering runs. These toothy predators cruise the offshore waters year-round but peak during cooler months when baitfish concentrate along temperature breaks. A good wahoo can easily hit 40-50 pounds and their razor-sharp teeth make wire leaders essential. They're notorious for cutting off poorly-rigged baits, but when everything comes together, few fish provide such raw power and speed. The key is high-speed trolling with flashy lures that trigger their predatory instincts.
Blackfin Tuna might not grow as large as their yellowfin cousins, but they make up for size with pure determination. These 15-25 pound dynamos are built for endurance, using their sickle-shaped tails to wage long battles that test both angler skill and tackle strength. They're most active during cooler months when they move closer to shore chasing baitfish. Blackfin respond well to both trolled lures and live bait, especially when worked around oil rigs and other offshore structure where they school up to feed.
Atlantic Sailfish represent the crown jewel of any offshore trip, combining spectacular jumps with surprising strength for their streamlined build. These magnificent billfish use their sail-like dorsal fin for herding baitfish, creating feeding opportunities that make for exciting angling. While they rarely exceed 50 pounds, sailfish are considered one of the premier light-tackle gamefish due to their acrobatic abilities. Port Aransas waters see consistent sailfish action, particularly during spring and fall migrations when they follow baitfish movements along the continental shelf.
A 12-hour charter represents serious fishing time and gives you the best shot at multiple species and trophy fish. The extended duration means traveling to prime fishing areas without rushing back to port just when the bite gets good. Southwest Sportfishing has built a customer favorite reputation by consistently putting anglers on fish and providing the kind of personal service that keeps people coming back season after season. With limited capacity and Port Aransas being a renowned fishing destination, these trips book up fast during peak season. Don't wait until the last minute – reserve your spot now and get ready for a day of fishing you'll be talking about for years to come.
Step aboard this classic 1979 Chris Craft Convertible, a proven 36-foot sportfisher that's built for serious offshore adventures. Twin 250HP Caterpillar engines push this beauty to 25 knots, getting you to the fishing grounds fast and bringing you back with coolers full of fish. The flybridge gives you commanding views of the Gulf while you're hunting for schools of tuna, mahi, and marlin. Down below, you'll find everything needed for those long 12-hour charters - air conditioning to escape the Texas heat, a full galley for meals, comfortable sleeping quarters, and a proper head. The fish finder and radar keep you on top of the action while GPS gets you to those secret spots where the big ones lurk. With room for 6 anglers, there's plenty of space to work multiple lines without tangling up. The icebox and refrigerator keep your catch fresh and drinks cold as you chase wahoo and sailfish in Port Aransas waters. This is serious fishing from a boat that knows how to handle Gulf conditions.
Istiophorus AlbicansThe ultimate trophy fish with that massive dorsal fin that looks like a blue sail when they're fired up. These billfish average 7-8 feet long and around 50 pounds, spending most of their time in the top 100 feet of water where they hunt baitfish. We see them year-round in our Gulf waters, but spring brings the best numbers when they follow the warm currents. What makes sailfish fishing so special is the aerial show - they'll jump, dive, and tail-walk like no other fish, changing colors from blue to black as they fight. Most folks release them since they're not great table fare, but the photos and memories last forever. We slow-troll with live bait or pitch flies when we find them lit up on schools of sardines. The secret is patience - let them fully eat the bait before setting the hook, and keep steady pressure without horsing them to the boat.
Thunnus AtlanticusThe smallest of the tuna family but pound-for-pound one of the strongest fighters you'll encounter. Blackfins typically run 10-25 pounds with that classic tuna build - dark backs fading to silver bellies with distinctive bronze-colored finlets. They school up in our Gulf waters from spring through fall, usually hanging around structure like rigs and drop-offs in 100-400 feet of water. What makes these fish special is their incredible stamina - they'll pull drag for what feels like forever, making long, powerful runs that test your endurance. The meat is outstanding too, with that rich, red tuna flavor that's perfect for searing or sashimi. My go-to technique is vertical jigging with small metals or chunking with pilchards. Key tip: downsize your tackle - use light fluorocarbon leaders and smaller circle hooks since these fish are incredibly line-shy with sharp eyesight.
Coryphaena HippurusThese golden beauties average 15-29 pounds and put on quite a show with their brilliant colors that shift from blue-green to gold as they fight. You'll find them around floating debris, weedlines, and oil platforms in our Gulf waters, usually within the first 100 feet of the surface. Spring through fall gives us the best action when water temps stay warm. What makes mahi so popular is the combination of their acrobatic jumps, strong runs, and that sweet, firm white meat that's perfect on the table. They're aggressive feeders that love chasing flying fish, so we'll skip ballyhoo or small lures on the surface to get their attention. Pro tip: when you hook one, keep your eyes peeled - they often travel in small schools, so be ready to capitalize with multiple rods.
Acanthocybium SolandriThe speed demons of our Gulf waters, wahoo are built like torpedoes and can hit 60 mph when they want to. These sleek fish average 3-5 feet long with razor-sharp teeth and distinctive blue stripes along their silver sides. We target them around the oil platforms and deeper blue water, usually between 50-200 feet down. Cooler months from November through March are prime time here in Texas waters. What guests love about wahoo fishing is that bone-jarring initial strike - nothing hits a trolled bait harder or faster. Plus, their white, flaky meat is some of the best eating you'll find offshore. The key to landing these speedsters is running wire leaders since their teeth will slice through mono like butter. We troll at 12-15 knots with diving plugs and skirted ballyhoo to match their feeding speed.
