Your only choices are at the marina in Santa Marta, the marina in
Cartagena, or at
anchor in Cholon. If more than a couple of weeks, I wouldn't leave it at
anchor in Cholon. If you leave it in the marina in
Cartagena, you will need to
haul out and renew the bottom when you return. You will not be hauling your
catamaran in Cartagena, so that means you will be going to Colon
Panama for bottom
work. The marina in Santa Marta is nice, but can get rough if a strong
weather system moves through.
Personally, I would keep it in
Aruba and sail to
Columbia when you are ready to
cruise again. The airline arrangements, marina arrangements, language,
customs and immigration are all much better and easier in
Aruba than Columbia.
