I rent my sailboat, a Sun Odyssey 47. This boat will allow you to travel from island to island and to visit Martinique, Santa Lucia, Grenadine's Island... in a very cosy way.
There are four cabin: 3 with double bed and one with bunk beds. There is 2 bathrooms: 1 at the front and one at the back.
On board you will find a large living room with a kitchen with a cooker, un hooven, a fridge a sink (and you will also find a bbq outside).
If you want you can also rent the boat with a skipper for additional fees of 130 € per day to pay directly to the skipper
