    What a great day!

    3/4 Day – Reef/Troll/Drift • 3 adults

    Today we had the pleasure of having the best crew and captain in the Florida Keys. Captain Robert and crew member, Claudia were amazing today. They were kind, patient (with a first time deep sea fisherman) and extremely knowledgeable. I would recommend this crew to anyone from novice to experienced fishermen. We ended up almost catching our limit of Yellow fin Snapper plus a few black fin tunas and a Rainbow Runner. They made sure to customize the experience around what we wanted. The perfection put into cleaning and packaging our catch was phenomenal. What a great day!

    Reported catch:
    Yellowtail Snapper
    Blackfin Tuna
    Response from Charter operator

    Wow, thank you for this amazing review! 🎣 Being called the best crew in the Florida Keys means the world to us. Captain Robert and Claudia loved having you aboard. It’s always special to share a first deep-sea trip, and what a first trip it was: nearly a limit of snapper, plus blackfin tuna and a rainbow runner! We’re so glad we could tailor the day to what you wanted, and that you noticed the care that went into cleaning and packing your catch. Enjoy every bite! Thank you for recommending us to anglers of every level. We can’t wait to have you back on board for your next adventure! 🌊☀️ — The Infinite Blue Charters Crew

    Highly recommend Infinite Blue Charters

    Full Day Trip – Reef/Troll/Drift • 5 adults

    We had a fantastic experience with Infinite Blue Charters. There were 10 of us in our group so we chartered two boats. Both captains and their crews (all active duty members of our awesome military) were extremely friendly, courteous, and accommodating from the time we stepped foot on the dock until we left with our perfectly cleaned catch. The boats were very clean and the tackle was in good operating condition. The crews were very attentive and took care of our every need. Captain Roberts & Captain DD were absolutely awesome! Everyone in our group appreciated how well both captains took care of every detail. Both gentlemen have wonderful personalities and a great sense of humor as well. We did very well on the Yellow Tail snapper and although the dolphin bite was off, the captains kept us on fish. We had a great time from start to finish & can't recommend booking a trip with IBC highly enough.

    Response from Charter operator

    Thank you so much for this wonderful review! We’re thrilled your group of 10 had such a great day on the water with us. Captain Roberts and Captain DD take a lot of pride in looking after every detail, and it means a lot to them (and to all of us) to hear how much you enjoyed their company. We’re especially proud of our active-duty crew members, and we’ll be sure to pass your kind words along. Way to go on the yellowtail snapper! Even with the dolphin being stubborn, we’re glad the captains kept you on fish all day. We’d love to have your whole crew back aboard soon. Tight lines! — The Infinite Blue Charters Team

    Great trip with family and friends!

    3/4 Day – Reef/Troll/Drift • 5 adults

    We chose the 6 hour trip with Infinite Blue Charters on their 50' Sea Ray with Captain Robert. We were greated at the doc by Captain Rob and First Mate James. The captain is former military and starts the trip off by going over safety and explaining the features of the boat. Once on the fishing grounds, Rob and James are working hard to keep the fish in the area with chum and continuing to change the rigging based on what the fish want that day. We caught one Mahi after some Yellow Tailing, but Captain Rob had one more trick up his sleeve before we headed back. We fished a wreck and caught three big Amberjacks that put up a great fight. We all had a great time and if you choose the 50' Sea Ray you have the option to get cooled off in the comfort of the air conditioned cabin when moving between spots. Captain Rob runs a first class operation from the start of your trip until the he hands you your perfectly fileted fish! We will be using Infinite Blue Charters and requesting this boat with Captin Rob on our next trip to the Florida Keys!

    Reported catch:
    Dolphin (Mahi Mahi)

    what a day

    3/4 Day – Reef/Troll/Drift • 2 adults

    5 Stars — Outstanding Charter My son Chase and I had an incredible day with Captain Rob and his mate Christina from Infinite Blue Charters. Hands down one of the most professional, organized, and well-run fishing trips I’ve ever been on. Rob and Christina worked seamlessly together, kept us on the fish, and made the entire day enjoyable from start to finish. Both are U.S. Armed Forces veterans. Their teamwork, discipline, and attention to detail absolutely showed in how they ran the trip. Great people, great fishing, and an outstanding experience. We would absolutely fish with them again. Highly recommended! 🇺🇸🎣

    Amazing First Time Family Charter

    3/4 Day Trip - Reef/Troll/Drift • 4 adults • 2 children

    Captain Robert was very friendly, thoughtful, and professional. He and his first mate did an excellent job keeping the four of us, including the kids’ (12 & 9), hooks baited and helping us catch many keepers including a couple dozen yellow tail, three amberjacks, and a Mahi. Plenty of fish for dinners all week. Due to morning weather and it being our first time, he proactively upgraded us to the larger boat! The interior cabin during the rain while heading out was awesome to have and also served as a great spot for our 9 year old to take a nap while blue water trolling. The kids had a great time. Great memory for our family. We look forward to another trip with Infinite Blue when we can make it back.

    Response from Charter operator

    Thank you for sharing your wonderful experience on our fishing charter! We are thrilled to hear that Captain Robert and his first mate provided exceptional service and made your trip memorable. It's fantastic that they ensured the entire family, including the kids, had a great time and were successful in catching many keepers, including yellowtail, amberjacks, and a Mahi. We are pleased that the upgraded larger boat and the interior cabin added to your comfort and enjoyment, especially during the rain and trolling periods. Creating great memories for families is what we strive for, and we are delighted that your experience with us will be cherished. We can't wait to welcome you back for another adventure with Infinite Blue when you return. Thank you for choosing us for your fishing excursion!

    What a day on the water! Our 6-hour trip had a little bit of everything, and our anglers headed home with a cooler full of variety and memories to match. Wahoo, the star of the show! These speedsters hit hard and run fast, and landing one is always a highlight. Yellowtail snapper, a Keys classic. They’re beautiful fish and some of the best eating in the ocean. Barracuda, which brought plenty of drama with their explosive strikes and acrobatic fight. Skipjack tuna, hard-pulling fish that kept the rods bent and the action steady. From working the reef for yellowtail to trolling for pelagic, this trip showed what makes fishing the Florida Keys so special: you never know what’s going to hit next

    Another great day on the water! Our 6-hour trip delivered steady action and a mixed bag that kept everyone busy from start to finish. Blackfin tuna, the hard fighters of the day! These fish dig deep and test your arms, and they’re a real treat at the dinner table. Yellowtail snapper, a Keys favorite that’s fun to catch and even better to eat. The bite stayed strong all day. Mackerel, fast and aggressive fish that hit with plenty of action. They were a blast on light tackle. It was a great mix of reef fishing and chasing pelagic, the kind of variety that makes the Florida Keys one of the best fishing spots around!
