You may find it hard to find a boat big enough to take on three crew. Much easier with one or two people. A lot of boats go to Mexico and a fair number to Panama. After that not so many. A few go as far as Ecuador and that is about it. Virtually no one goes further south than that since you are going against a very strong current and Peru has very few harbors. If people want to go further south (Chile has lots to recommend itself) they typically head offshore to Galapagos and Easter Island and then come back to coast at whatever latitude they want to be at. But the number of boats a year going this route is very small.
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.
