Trained for Keys waters
Hey Key West boater. Tell me what's going on — electronics issue, Marquesas run question, permit on the flats, reef fishing regs, or hurricane prep for the Keys. Real answers, not generic search.
Running to the Marquesas this weekend — what should I plan for?
The Marquesas are 25nm west of Key West through some of the shallowest backcountry water in Florida. The main concerns: navigating the flats running west (shallow spots can be 2-3ft at low tide), wind exposure (no protection once you leave Mule Key), and fuel planning (no fuel out there). Northwest Channel is your deepwater exit. Anchor inside the lagoon on the east or south side for protection. Carry spare fuel, working VHF, and flares — you're 2+ hours from help. What's your boat size and are you overnighting?
