I came through the
canal South to North this past December with a 46ft
catamaran, I used Delfino Maritime, a guy names Pete Stevens. I can highly recommend him, he is bonded, efficient and helpful, a Brit been living there for over 30 years and well connected locally..he made it all very easy and quick to get through and actually saved me
money ! he will also clear you in and out of the country, send me a PM and I will give you all his contact info...I am going through again in a few months and will be using him again....smooth sailing
