Great trip report! You were there just after us this summer.
I was looking into chatering from Grenada this summer but was concerned with sailing to weather all the time. After reading your report, I think I'll stick to St. Vincent and back again.
I feel badly that your 1st experience with the boat vendors was @ Union where they are the most aggressive we've seen. Glad you gave them another chance and got to know them a little too. They are much more organized and pleasant everywhere else.
We had a BBQ with Romeo as well, one of our best meals in the Caribbean!
Was it expensive to do a one way charter?
