There's aren't a lot of Marinas
on the east coast
and the couple that are there are a total mess. Last I was there, which was over two years ago they had planned on putting a new marina and resort in Limon, but things go slowly in Costa Rica
so that may still just be a plan
On the west coast
there are several, banana bay is the only one I can remember off the top of my head
, but i am sure a good google
search would give you some other options, to be honest i haven't spent much time on the west coast
of costa rica so I can't give you any first hand experience.
I am told is much more "cruiser friendly" as far as facilities go. Costa Rica is beautiful, the Tico's are amazing people, extremely nice and just plain cool, but they take out their aggression on the road
Theft is high, or at least the expats that live there feel it is, pretty much all their houses are compounded in and you'll see most communities pitched to expats as "secure". They are huge into the environment
, an extremely high number of Tico's own homes (not necessarily to our standards however), they have great healthcare, good food
and pretty much everything you could want is available if you have the money
to buy it. The roads are terrible, there are no street signs even in big cities. I don't know how prices as far as importation have changed since the CAFTA agreement, it was quite expensive to import
things like cars permanently last I was there, but again that was before CAFTA.
