    aweome day on the water

    Full Day Trip on December 24, 2025 • 4 adults

    Mark is a great guide and a great guy! Thanks for what you do for vets! He had us on fish all day! Caught over 60 fish including two large sharks - a 6ft bull and 5ft blacktip. Had monster tarpon hooked up three times but they broke off... super exciting seeing a 6 ft beast launch itself out of the water like that. Mark worked hard and kept up with everything, even with three fish on at the same time. We are in town for another week and are booking another trip with Mark... gotta get one of those tarpon!!

    Awesome Capt and Boat

    3/4 Day Trip on December 26, 2024 • 5 adults

    I have been fishing for over 40yrs, been coming to Keys since I was 10. I am an avid fisherman and Capt Mark is an incredible Capt and even better Man. We decided to take our 3 boys here for Christmas this year and so worth it. I have never seen a Capt do all he can to make sure you catch fish and we sure did. His primary focus is making sure not only to catch fish but in his words have a “MEMORY” you won’t soon forget. Aside from all the fish, we caught, it was the Memory he was looking for and boom my son hooked into 160-170lb bull shark and what Battle. Mission accomplished. Mark was in the Navy and my son on board is heading to The Naval Academy, Annapolis and Mark took time at the end of the day to have a sincere conversation and words of wisdom and advice for my son, that put my wife in tears. I can’t say enough about Capt Mark and the time we had. Go NAVY🇺🇸

    Dec, 2024 Fishing Charter

    3/4 Day Trip on December 7, 2024 • 3 adults

    Captain Mark was an excellent guide and gave us lasting memories to take home after our short trip to the Keys. Despite windy conditions, and changing water temps, we fulfilled our wishes to pull in some large fish. We caught a huge ray and shark, among many snapper and other fun fish. We got to take our fillets to a local restaurant that did an excellent job with preparing us a meal. Cap. was very personable and made the most out of otherwise unfavorable fishing conditions. Will definitely be returning clients and would recommend to anyone looking for a great fishing experience in the keys 🐠🔑

    Great Captain and awesome time.

    3/4 Day Trip on September 4, 2024 • 4 adults

    First and foremost, I have much respect for his military service and his work with veterans. Captain Mark put us on areas that were rich with shark, tarpon, cobia, snapper and ladyfish. Each of us landed a heavy weight: 2- bull sharks and a 6' tarpon. We would definitely book with Capt again, for the laughs and good times we all enjoyed. Cap't is a Texas Longhorn, and my cousin is a Michigan wolverine, which added to the fun. Go Longhorns! Just joking. We finished the trip a Lazy Joe's where they prepared our catch to perfection. You know it wouldn't be Florida without a little storm!

    Amazing day with Capt Mark

    3/4 Day Trip on July 17, 2024 • 2 adults

    Met Captian Mark with no issues and he told us the game plan. We caught something for dinner and I wanted to catch some “memories”…boy did we. My wife isn’t very experienced at all and he was so patient and family friendly. We caught some snapper and trout and then moved locations and caught multiple sharks and jacks! Even caught one 100 lb shark on a light setup that was so fun to fight. At one time I counted 8 sharks circling our boat. Such a cool experienced to see. He cleaned all the fish for us when we returned to the dock and recommended a place to cook our catch for us and how to prepare all the fish. We cannot thank Capt Mark enough for all of his work and knowledge. We will definitely recommend him and be back next year to use him again. Thank you for an amazing day. From John and Susan.

    Trip of a lifetime

    5 Hour Shark trip on March 3, 2024 • 2 adults • 1 child

    Captain Mark was amazing. He's definitely a professional at what he does. I took my 14 year old nephew. I expressed to Mark that my main goal was for my nephew to catch a large shark. No matter how long it took. Captain Mark had him hooked up with a monster in 10 minutes flat. And several more after that. Which allowed us to also move on other species after that. He was very knowledgeable on where and when to fish the different areas. Everytime time either mother nature or the bite threw us a curveball. Mark had an answer. He kept us on the fish all day. He was also very patient with a couple novice fisherman. I would absolutely book with him again.

    Full Day Trip on March 25, 2025 • 3 adults • 1 child

    Great day on the water with Captain Mark!! We booked 8 hours which I highly suggest for a full day on the water. We caught close to a 100 fish total!! Mangrove Snapper, Trout, Mackerels, Jacks, a really nice Goliath Grouper and others. Captain Mark knows his stuff and was constantly putting us on fish! We took our catch to Lazy Days and they cooked it up right! You can’t go wrong booking with Dauntless and Captain Mark!!

    Amazing Experience

    3/4 Day Trip on March 15, 2025 • 3 adults • 1 child

    We spent the day out on the water with Captain Mark. My family and I had a great time. He brought us out to 8-10 locations and we made great use of our time. He put us on fish at every location. I'd highly recommend giving him the opportunity to share the day with your family for some great fishing. He's also very involved in taking veterans out on trips and runs a large operation giving back to the community.
