When I did the trip a couple years ago, the best route was Panama to St. Andreas Island. to Providencia (both Colombian islands) and good fuel and food stops, to Gunaja, Honduras (easy, safe fuel stop), then up to Isla Mujeres then to Key West. Good luck. Should be an easy trip this time of year.
Looks like San Andreas to Rotan to isla to key west longest leg about 430 miles San Andreas to Rotan gonna hug coast along nicaragua and Honduras came down 8 years ago key west to Cayman to San Andreas to panama I only have little over 500 miles cruise range.
Let me know if you are coming by Grand Cayman for a stop and would like an extra crew to the states. I was looking to head back to the states and could help with fuel and food. This would be an exciting way back. Thoughts?
Unless something has changed recently, you can't easily get fuel at the dock in Providencia--you have to jug it from a gas station. Doable, but not easy for 500 gallons. So, I would say Panama to San Andres (Colombia) to Roatan, Honduras, to Belize and Isla Mujeres, Mexico, to Key West. You might want to check with your insurance about stopping at San Andres, as it is part of Colombia.
