For a while now I was harbouring the idea to cross the Atlantic not by plane but by any sort of oceangoing transport, in an attempt to travel slowly, reflect upon my time in South America and getting back to Europe.
Now, I don't really have a clue how to start looking for opportunities. I know from some people in the Canary Islands that going by sailing boat is an option. Their approach is to stay around the harbour area and ask around for arising opportunities. I found the following part of an answer on this site also (but it doesn't mention in detail where in South America I might find a boat):
Morten: "An other option to cross the Atlantic Ocean is by private sailing boats. But because of the sea (wind and currents) the season is from April to June. In the other months the sailing boats leave to Europe from the Caribbean Islands like Martinique. So you have to go there first."
I'm in Chile right now. I can reach Argentina, Peru, or southern Brazil. I don't have a fixed schedule when I need to get back to Europe. I also don't mind the destination country. I have no experience on sailing boats though I've been on other vessels before. I also have an ocean based profession if that's any help. I cannot afford to spend a lot of money, but a few hundred Euro would be OK.
My question is: what is the best way to look for opportunities? Where, in southern South America, am I most likely to find sailors going to Europe?
