Keen M Sport Fishing

Keen M Sport Fishing and their dynamic crew invite you to join them on board one of their boats. The ‘Keen M’ is a 41’ vessel, built by Michael Fitz in 2005. She has been featured in various fishing magazines, such as Salt Water Sportsman, Marlin Magazine, Guy Harvey Magazine, National Geographic, Dive, and Canada Diver, as well as in some BBC series. If that’s not impressive, then nothing else is!

Enjoy an eco-friendly crew and hone your angling skills. Have fun with your fishing buddies or take your whole family out on the water. The professional team of Keen M Sport Fishing will help you make an outstanding catch possible, be it Tuna, Mahi Mahi, Wahoo, and Red Snapper or any possible Billfish that these waters have to offer.

All you have to do is pack some cash for live bait and get ready for a lot of action. The Keen M is powered by a 580 Cummins Diesel engine and has enough room for up to 6 passengers. She is also outfitted with navigational and fishfinding electronics, a full head, and various professional accessories.

Try your hand at bottom fishing and trolling. Go for jigging, spinning, and deep sea fishing or even fly fishing if you let the crew know in advance. If someone from your party doesn’t have the itch to fish, they will be able to go snorkeling.

Your trip will include all the necessary gear and tackle by Shimano and Okuma. Cookies, potato chips, apples, pineapples, watermelons, drinks, ham, and cheese will also be available on board. The only thing that’s missing is you!

We all at Keen M love fishing, our captains, mates, and guests. We all love it and enjoy sharing our ocean experience with all our clients. Our favorite type of fishing is whatever is biting the best! Our company's specialty is Atlantic Sailfish and light tackle bottom fishing. We also have a passion for large Sharks in the area, all of our Shark fishing is catch-and-release. We even swim with them sometimes – ask about our cages!
