Our boat is in St. Lucia and we went down there for the first time in November last year. Had a blast. Much longer sailing legs as the sail from St. Lucia to the southern end of St. Vincent took most of the day - I want to say 8 hours?

We had just as much fun, although we didn't dive at all but we're fine with that. We went as far south as the Tobago Cays and then began our trip back.

A one way from St. Lucia to Grenada or vice versa would be a great way to do it. Seems 2 weeks is also a much better way to do it as well, we'll probably do at least 10 days next time if not 2 weeks.

We may head north next time to Martinique as well, possibly further. Lots of options there!
