It is posible to save 165 NM of navigation by crossing the state of Florida via Lake Okeechobee instead of doubling the Keys. Going counterclockwise, you enter through the Port St. Lucie Inlet, then motor up the river, and finally connect to the Port St Lucie canal. This canal leads under many bridges, past Indiantown, through two locks, and into Lake Okeechobee. There are draft and bridge clearance restrictions. Excellent information is available on the super Blue Seas website.
