Are you set on the BVI's? Opportunities are available to book either a cabin or a single berth to sail in the Grenadines each month December thru March. Great boat and experienced crew, 10 years chartering in the Grenadines. charters start and finish in St. Lucia so easy to get to from Atlanta.
Below is a link to a blog an Australian woman wrote who was on a charter we did in January 2016.
