We are picking up our new to us boat (Carver Mariner 350) this weekend in the Ft. Lauderdale area and will be bringing it back to the Clearwater area. We have changed our original plans and have decided to go through the Keys instead of the Okeechobee canal. Any input, suggestions, or warnings? Once we leave Marathon Key and head towards the coast, how far offshore will we be? Will we still be able to see the coastline? Anything special to see along the way? How long should we plan on? We will be staying on the boat at marinas along the way. I have a chartplotter, radar, Navionics on a tablet as a backup to the chartplotter, one fixed and one handheld VHF radio, all necessary USCG gear, and the current Dozier's Waterway Guide. Any and all input would be greatly appreciated!
