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!

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.
