Either option sounds like it will work nicely, St. Martin seems to often come to mind when I'm thinking of the Caribbean.
Being a seasoned sailor, do you think it worth my while to do the STCW in the States whilst I am still here or would there be an opportunity to do it in the Caribbean, maybe even a little less expensively? Also, given the fact that I am a (fit and able-bodied) woman in my 40th year, am I dreaming thinking that someone would actually want to take me on as paid crew? Not new to sailing but new to the cruising life... thanks again for the info, as well as the patience in answering my questions!!
