About Your Trip

This is the perfect trip for your Hawaii trophy hunt. Just a short boat ride offshore and you'll be in prime waters for sailfish, marlin, wahoo, yellowfin tuna, and more. Capt. Shawn's boat is outfitted with Shimano reels and quality rods and tackle, all IGFA qualified in case you catch a potential record breaker. Equipped with a sturdy fighting chair, you'll be in comfort when fighting your quarry. After the battle, you can take a load off in the air conditioned cabin equipped with all the amenities you need to recharge for the next fish.

About Your Guide

Captain Shawn Slattery with Kona Cowboy Fishing Charters was born into a commercial fishing family. After the oil spill in the Gulf of Mexico, he decided it was time for a change, so he began offering private charters.

He took his commercial knowledge and set out to hunt trophies in Kona, and never looked back. He has a combined 35 years of experience between commercial and recreational fishing, and he's excited to share his years of knowledge with his clients.

I have fished all over the world and would rank Captain Shawn and crew among the very best guides I have fished with. Captain Shawn’s commercial fishing background and fishing network give him a solid edge. He knows what he is doing and has all of the right equipment to get it done. Better still, Shawn is great company. Interesting and personable, Shawn made our day on the water a wonderful experience. I look forward to fishing with him again. Book a full day for the best experience. Bring a camera for the whales and lots of sunscreen.

Our first trip to the Big Island to hopefully fulfill a life long dream of catching a Blue Marlin. Fortunately we booked Kona Cowboy with Captain Shawn, Kimberly & Hannah. My dream was catching one Marlin, I caught 5!!! The largest weighing 400lbs!!! It was the best time I’ve ever had fishing & I owe it all to Capt. Shawn & his crew. I truly believe he may be the hardest working captain to hook you up with a Marlin also.
