Grouper Fishing
Target trophy Grouper species in the Florida Keys' productive waters. Our charters use heavy-duty tackle (up to 100lb test) to battle these powerful fish in deep reef structures. Clients receive expert guidance on techniques and equipment. The service includes live bait, rods/reels, and cleaning of your catch for transport home.
Snapper Fishing
Pursue vibrant Snapper species across the Keys' coral reefs. We provide specialized tackle and bait to optimize catches in varying conditions. Trips include navigation to prime locations and instruction on best practices. Our conservation-focused approach ensures sustainable harvest while maximizing angler success.
Offshore Fishing
Venture beyond coastal waters for pelagic species like Sailfish and Kingfish. Kite fishing techniques are employed for surface action, while deep-dropping methods target bottom dwellers. The 26' Parker boat's stability and speed ensure comfort and efficiency during extended offshore excursions.
Tarpon Fishing
Pursue legendary Tarpon in flats and bridge systems. We utilize light tackle (40-60lb test) for thrilling battles, with expert casting guidance provided. The service includes polarized glasses for spotting fish and strategies for navigating tidal movements in key habitats.
Permit Fishing
Target elusive Permit on shallow grass flats using precision casting techniques. Our guides leverage extensive local knowledge to locate these challenging fish during optimal tidal windows. Trips include crab bait preparation and presentation instruction for improved hook-up rates.

We had a grand time with Captain Dan. We did 4 half days on yellow tail and snapper and caught a gracious plenty. He is very professional and cordial, knows his stuff, and full of great stories. What I most enjoyed was trading great book recommendations with him as he turned out to be an avid reader! You will have a great experience.

THANK YOU DAN!! Caught 25 mangrove snappers and 3 yellow tails with my group. Dan was nice enough to let us fish off his dock while he cleaned up our fish, and we caught our first tarpons and cudas. Will be back for more whenever were in Marathon

Never thought I'd see my picture on a fishing charter webpage but there we are with a huge king fish. Thanks to Captain Dan on a day the fish weren't biting well at all , he does know his stuff.

My wife and I did an all day charter with Dan, Sunday 8 Sep. We caught lots of Yellow Tails, some just under sized grouper, and several bigger fish that were stollen by sharks. I learned some new tactics that I'm going to try on my home reef off Hernando Beach. I caught an awesome Tarpon at his dock at the end of the day by following his guidance.

Planned this trip specifically to fish. Had "Capt. Dan" lined up to take us out our first day. Sent $100 deposit. Showed up and he wouldn't even answer his phone. Got 2 other people that knew him to call and he answered them. DONT WASTE YOUR TIME OR $!!!

Dan goes over and above to make your fishing experience great! A great teacher for first-timers, but if you're a slow-learner like me, he has tons of patience and is right there to guide you! We had a great haul of snapper and a fun time!
