We purchased a yacht in the DR that was registered there. It was a lot of work to get it de-registered and the previous owner had to pay them $4000 to do it. Then they wanted to hit us up for $1100 to leave but we negotiated it down to $110. Since your vessel is not registered there it should be easier. If you speak Spanish you could attempt it yourself, otherwise consider a service
out of Miami
such as http://www.registeryourboat.com
. You will need to have all your BVI documents officially translated into Spanish and on and on. When all that is done and the official moneys are paid just understand that it's a country that operates on tips to get anything done in a timely basis but these money's can be negotiated. If the current
owner would agree to sail with you to Puerto Rico
and transfer ownership
there it would be more straight forward but otherwise if it's the boat you want jump in but don't plan on anything happening super fast in DR.
