100 miles in 10 to 12 hours, don't think so. For planning purposes assume 5 knots and you should be in the ballpark. Someone mentioned that there are places to stop. This is two long days. Have fun.
Back to Grenada in early December. Not sure I will remember how to sail. Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
