Pete, I don't know where you get this result, but it is wrong. Best sailing time for 2 person team is 2 days 8 hours and best solo paddler did it in 3 days and 2 hours.

You can take Tiki, if you can lanch it unassisted from highest watermark on a beach, and propell it a mile into tidal creek under fixed bridge 12 ft wide and 8 ft tall. There are some difficult navigation getting to Everglades City and crossing Florida Bay...

Nobody restrict your time, you can sleep as long as you want - you have a week to finish.
When I did this race on old A-cat, I slept all nights. (Days were long enougth to wear me down <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> )
