Captain Robert was fantastic!
3/4 Day – Reef/Troll/Drift on April 5, 20264 adults
We went on a 3 generation fishing excursion today with Captain Robert. He provided an excellent experience that included catching loads of yellow tail snapper on the reef and two Tuna while trolling. It was a windy day that caused rough seas but Captain Robert navigated us to areas that produced enough fish to catch our limit. When we returned to the marina Captain Robert spent 90 minutes filleting and bagging our fish to take home. He gave us restaurant recommendations to where we can take our fish and have it prepared tonight! We would highly recommend a 6 hour reef/drift/troll excursions with Captain Robert!

Full Day Trip – Reef/Troll/Drift on March 30, 20264 adults
We had an outstanding 8 hour charter with Captain Robert. We caught tons of yellowtail, bonita tuna, and even a few barracuda. Captain Robert is extremely helpful and patient. This was the best day of our vacation so far. Captain Robert cleaned all of our fish for us, it was extremely time saving for us and fun to watch. We can’t recommend Robert and his crew enough! He even gave us tips on how to prepare our fish once we got it home. 10/10!

Captain Robert provided a wonderful experience. Full service and excellent knowledge of fishing, boating, and The Keys. He safely navigated choppy seas and got us where there fish were! We did the 6 hour trip and caught 22 Yellow Tail Snapper and 2 Barracuda. They were so good! Thank you Captain Robert and Infinite Blue Charters!

8 hour trip
Full Day Trip – Reef/Troll/Drift on August 4, 20255 adults
Man, what a day. We arrived at the dock, and Captain Robert's military influence was apparent. We were given a quick tour of the boat, life vest locations and he clearly outlined the safety measures we would follow while fishing with him. A quick and comfortable 25 minute ride in his air conditioned cabin aboard his 47 foot Sea Ray had us feeling like royalty. We started with drift fishing for Yellowtail Snapper, and in less than 2 hours, the 3 of us had caught our limit. Next, we hit the big water trolling for Mahi. I knew it would be tough as the heat index for a solid 2 weeks had been above 105°. The warm water forces the Mahi to hunt squid at night and just reserve energy during the hot day. Regardless, the captain worked hard to get us on the fish, and we each had an opportunity to get at least 1 in the boat. We finally hit "the wrecks" for Amberjack and that's when the trip became epic. On our very first attempt to bring one aboard, SOMETHING else grabbed onto our Amberjack. Big grouper? Shark? Loch Ness? Who knows. We fought it for 45 minutes gaining some ground, while the beast then pulled line off. Captain Robert backed the boat up numerous times attempting to help us bring it in. But after 45 minutes, the rod finally snapped. We all let out a moan of disappointment, and I was shocked to hear the Captain yell "Keep Going"! Gotta tell ya...a shorter rod makes reeling in Moby Dick much harder and it was only a minute or 2 after the rod broke, that the line broke as well. We LOVED our day on the water, and we will have a "one that got away" story to tell to family and friends FOREVER. Just wish we could have got a peek at what this thing was. Thank you so much Captain Robert. You are a helluva Captain, and we hope to fish with you one day again soon! Truly we thank you for a GREAT, great day!
