aanvaart

Aanvaart is a nautical term in the Dutch language that refers to the approach of a vessel toward a harbor or navigable channel from the open sea. It designates the inbound phase of a voyage, during which navigators align the vessel with prescribed routes, adjust speed, and coordinate with harbor authorities or pilots before entering the port. The term is used in nautical charts, voyage plans, and port instructions, and is typically contrasted with afvaart, the departure from a harbor.

In practical terms, aanvaart involves navigation through the final approaches, traffic management within the harbor entrance, and preparation for berthing or anchorage once the vessel reaches the inner harbor area. It may require pilotage, the use of tug services, and compliance with local rules and pilot regulations. The concept remains embedded in Dutch-speaking shipping practice and is encountered in professional documentation and training materials for mariners.

Related terms include scheepvaart (shipping), haven (harbor), aanvaren (to approach), and afvaart (to depart).
