Customs & Immigration Fees During a Charter

I am doing a charter next April – departing St. Lucia, sailing the Grenadines and dropping off the boat in Grenada. I am trying to get a better idea of the Customs & Immigration fees both my crew and I will encounter.

Does anyone know what is costs to clear out of St. Lucia, clear in and out of SVG and clear into Grenada (per person) and what about the boat (Moorings 50)?

Thanks in advance for any info.

we did a charter st vincent, bequia, union island, tobaco cays and return, did not go into any customs office. was that ok?

Not sure what the costs are as they are always included in the cost of the charters when we go, but I do know that in St. Vincent it is less for "crew" than for "charter guests" so if you are doing a bareboat charter be sure to say you have crew instead of charter guests, which I think would only apply in a crewed charter situation. The customs offices on St Lucia have set hours posted, but often the officer is late in showing up.
sailn, no need to visit C&I in your case as you never left the country.
