As you're coming around the bend just after Lattitude towards the fish market its the second right and they are immediately on the left. Oscar Presiado is the captain and I highly recommend his services. He speaks perfect english and is very knowledgeable about the sea of cortez/ wind of cortez. He has countless trips out to bird island and the boat they have is very comfortable and quick. They also have a 40ft catamaran that he takes out for sunset sails if there is enough wind. Highly recommend his services.
