I've done it in a my boat in about 14 hours at 6-7 knots. There is no straight line heading from Marco to Marathon. It concerns me a bit that you actually asked this question. It suggests that you are a coastal sailor that usually doesn't get out of sight of land and doesn't use charts
. Since you have posted here it would appear that you have a computer. I suggest that you download Opencpn
and then go to the NOAA web page and download the chart package for Florida
. Both of these are free, so cost is not an object. Learn to use it to plot your own course. If your computer is a laptop
buy a usb GPS
it into the computer and take it with you when you go. With the typical thunderstorms in FL Bay in the summer you could be blown off course or have to go significantly off heading to avoid one. If you are simply trying to follow a heading that some one gave you at this point you now don't know where you are, and you don't know what direction you need to go to get to your destination
. That is usually what we call lost
. Modern electronics
have surely simplified and reduced the skills needed for navigation
, but you do have to have some. Reading a chart, be it paper or electronic, and plotting a course is a pretty basic requirement. It's not that hard and a few weeks is plenty of time to learn how to do it, so do it before you go!
Now for some advice on the course. Make sure you clear the shoals off of Cape Romano before turning southeast towards Marathon, then watch out for the shoals NW/N of Marathon. Head
for Marker G17 at approximately 24 48.920, 89 09.135 and follow the marked channel to Moser Channel through the 7 mile bridge. In between have fun dodging the pots. This somewhat assumes you want to stop at Marathon. If you don't actually want to stop at Marathon, Yacht channel and the Channel Five bridge are good options.
