Thanks for your response about OpenCPN. I have already been looking at it and would appreciate opinions regarding it. I have the two computers, but they are not waterproof. So I was thinking that they would be secondary or backup devices.
Costa Rica is a terrific country, but it's not for everyone. I have been to many different areas of the country and it is full of natural wonders and friendly people. The infrastructure varies widely. Roads are in fair to poor condition. Electricity is generally reliable. You can drink the water, but some areas have shortages and water is not available 24 hours per day. Some areas do not have internet service.
I live in the center of the country in a small town named Zarcero. I have been here 5 years and really like it.
Costa Rica - Zarcero
The country has many different micro-climates. Zarcero is cool. I sailed into Golfito earlier this year and it was HOT!
It is best known as the place where the only tax free import zone is located. Import taxes are very high, so many people go there to buy appliances and electronics. It's a good deal if you are near to it, otherwise it depends upon how easy it is to get your purchase home.
There isn't a lot more there. It's located near some good national parks and is a quiet little place.
I wouldn't recommend that anyone come to Costa Rica and buy property. Property is very easy to buy and very hard to sell. Many people who buy regret their decision. Over half the people who move here leave within a year. There are numerous reasons.
This deal sounds too good to be true. So it probably is.
