Do not just dismiss shipping the boat after first glance. Dockwise Transport is where everybody looks first and their prices are quite high....... they are the premium outfit. There are others.
Another shipping option is the "deck cargo"
Finally, there is the "container ship" system of shipping boats.
Shipping the boat to Chile certainly is an idea but:
1. I am pretty sure Dockwise don't do South America let alone Chile.
2. Not so sure either about the "premium outfit" description. Another Cruiser Log moderator has had problems with them
3. Deck cargo? Problem with that is that the boat is exposed to the weather and seas boarding the ship. Deck cargo always was carried at shipper's risk and I am not sure that has changed.
4. Containership transport would, imho, be the best alternative but ouch, using the space allocated to at least two 40' containers (depending on the width probably four) will be really exensive.
In my opinion, leave the boat until it can be picked up at a later date or sold. When leaving it find someone who can look after the baot or lay up ashore in a secure compound or farmers barn.
