    I highly recommend booking a charter trip with Seasquared. I did a full day trip with Captain Alex and First Mate Mike on Blue Magic and it was fantastic. Both Alex and Mike were very friendly and worked very hard to make it a great trip for me and my boys. We have limited freshwater fishing experience and no saltwater, but they both helped us with the right techniques and friendly guidance. We caught our limit on Yellowtail Snapper and it was fantastic fun trying to outrun bull sharks to get our catch onboard before they stole it. After that we tried for Mahi then moved on to some great fun topwater fishing one of the reefs where we caught a lot of barracuda. We'd never fought fish that strong or that big so it was a fantastic experience.
