Since you are starting in Amelia Island, Fl you should be able to get down to Miami
in a week either using the ICW
or some overnighters running outside along the coast. Figure about 40 to 50 nm per day if you stay in the ICW
and do 6 kts or so. The advantage of going "outside" is being able to continue running day and night so your distance per day jumps to 100 nm or more. But not every day can you go outside, so you do the ICW on bad weather
- - From Miami to Key West
is probably another 3 or 4 days as you really need to do it during the daytime heading south so you don't hit something and incur mega-fines from the marine
- - Then from Key West to the Dry Tortugas
is a heavy push to do in one daytime shot, so a couple of days there.
- - There are multiple routes from Florida
(Cozumel or Isla Mujeres). One is to cross south from the Dry Tortugas
and run 15nm off the Cuban coastline to Cabo San Antonio then take a westward shot across the Yucatan
Channel. This is the shortest mile wise but you are pushing against the currents. You are looking at close to 400 nm so depending upon your boat speed over the ground it could be 4 days or more at sea.
- - Another is to play the currents in the Gulf of Mexico
and run due west north of the main current
taking advantage of a "loop current" that will help push you westward. And then south to the Yucatan
and Isla Mujeres and/or Cozumel. This route is not used too often as access to current
loop current information is not easy.
- - Finally, the "long way around" is to follow the US Gulf of Mexico
shoreline to Texas
and then to the Yucatan and around. Probably the "safest" route weather wise as you are running coastlines with places to duck inside in bad conditions.
