I have a boat in the BVI and often mail parts and equipment directly there. I use a company called Tortola Express aka Aeropost. They give you a mailing address in Miami and they then forward from there. It ordinarily is delivered the following day once they receive it in Miami. Understand that they will bring the packages through customs and upfront the fees but you will be responsible on pickup plus the freight charges. They have an office in Road Town where you can pick up or they will deliver. I have used many services over the years to include those located in St. John and St. Thomas but none has worked out as well as Tortola Express. They have a website and I urge you to take a look. The lack of major hastle is well worth it.
