Captain Magnus & mate Travis provide first class service! Always a great time!!

May 30, 2025

Captain Magnus is simply the best. You can’t beat the boat, the scenery, or the action. The captain and his first mate Mike put on a clinic and got us right on the fish. We were lucky enough to be heading in during the start of one of the legendary Key West sunsets and it was a scene from a movie. After all said and done and we were back to the docks Captain Magnus filet’d the black fin tuna we caught and gave us a recommendation of an amazing restaurant that would prepare it for us. Highly recommended. Thank you for everything!

Had an awesome 4hours on the water and brought back 17 fish. Great Capitan and first mate. These guys are awesome and will definitely get you on the fish. Double rods bent over several times.

It was my first time out on a charter boat and it was awesome. The mate and captain were great and we caught a few different kinds of fish. This is a must do as the boat is nice to take a break inside also.
