First of all I suggest to organize a one-way trip. In this way you can sail with the right wind and you don't must come back with front wind, that should be strong.
Martinica is perfect for beginning a sailing holiday in Grenadines because it is a french territory, very similar to our condition and it is very close to the best islands in this area.
In particular Le Marin is a good port where to take your boat or catamaran. Here you'll find all you need, like food, spare parts, informations and so on.
What you'll read below is a schematic route that you can follow to have a great cruise in this area. For each step I'll give you some basilar information like distance (NM), route, sea condition and so on.
