The port masters welcome you to the Dellewal marina website. We hope to provide you with the relevant information in this way before you visit our ports with your yacht. At the edge of the Wadden Sea, in the only natural bay in the Netherlands, we have pursued a very sustainable policy for over 25 years. Every year since 1987, we have received the International Blue Flag, the seal of approval for environmental friendliness, safety and a high level of service. And we are proud of that.
