I have a trip planned to big pine key. Ive got a 26 ft. boston whaler with twin 200 ob. Illbe staying in the north end of big pine key and docked there as well. Anyone who has any experience navigating this area? I would like to trek to the atlantic side. My charts show depth at one foot in a lot of areas. Shoals are clearly marked. I just dont want any surprises. Dave
