Captain Robert Williams has been fishing for nearly 4 decades. He's spent the last 5 years fishing in Marathon, Florida, making him a true local connoisseur of these waters. Choosing the path to become a licensed captain was an easy one for Capt. Robert. For him, taking guests out on the water daily is the best work there is!

    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.

    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

    Extremely nice gentleman who can catch fish!

    Full Day Trip - Reef/Troll/Drift • 6 adults

    We thoroughly enjoyed our trip today with Captain Robert! There were five of us in the group. We all caught so many fish pretty much from the start of the day. Most of our catch was in the snapper species.We first started out fishing out in the Atlantic and made two stops over there. We went into the Gulf side a a couple of more stops which rounded out our day. Every stop we picked up plenty of fish. Our final catch that we were able to bring back because they were of legal size ended up being 43 fish! Captain Robert cleaned each and every one of them and even provided Ziploc bags for us to transport them out. The boat was remarkably clean and well maintained. Being veteran owned and such a nice very hard-working guy we will definitely book him again! Highly recommend!

    Reported catch:
    Mangrove Snapper
    Yellowtail Snapper

What's biting with Infinite Blue – 50’ SeaRay, Veteran Owned in Marathon

The rain finally eases off in October, and the temperature drops back to a sane 85. The Tuna are at their height this time of year, with Yellowfin and Blackfin biting well offshore, and the Tarpon and Snook are still filling up the shallows.
