SailCaribe is based out of Fajardo on the east end of mainland Puerto Rico. They have a handful of mostly newer Lagoon cats and I think only one monohull right now. Have chartered from them a couple times and they do a good job. Easy flights into SJU and several large provisioning options on the way to the base from the airport including a Costco close to the airport. CYOA out of St. Thomas also will allow boats to travel to the SVIs as long as you are qualified - which with a captain you would be. They have a larger fleet so more choices and you have your choice of the SVIs, USVIs and BVIs. Never chartered from them but have heard great things. I don't think you'd go wrong with either of those companies.
