I'm going to be doing some traveling around the north coast of South America and the Caribbean. I'm not in a hurry, and I'd love to travel by boat, but I'm having a hard time finding information about ferries and boats routes in the area. Is there a good way to search for boat routes (or private boats that will take me where I want to go)?
Here are some examples of what I might like to do:
A boat between the Dominican Republic and Martinique. A boat between Martinique and French Guiana. A boat between French Guiana and Jericoacoara, Brazil. Etc.
I'm not all that particular about what type of boat it is, timely schedules, or price (within reason), I just think taking a boat might be more interesting than flying.
