We made this trip going the other way about three weeks ago. It was a great sail from Royal Island to Little Harbor. We had a great and very settled weather
window and enjoyed a full day of blue sky and 15 to 18 k winds from the SW.
Be very careful and go south around Royal island if you are going to Spanish Town. Do not try the direct route
to Spanish Town as there are lots of reefs
and heads that are not well charted.
Enjoy a great sail.
