The village Egmond aan Zee houses one of the lifeboat stations of the Koninklijke Nederlandse Redding Maatschappij (abbreviated KNRM), the Royal Netherlands Sea Rescue Institution. The KNRM is a voluntary organisation tasked with saving lives at sea. Along the Dutch North Sea coast, the Wadden Sea and the IJsselmeer are 39 lifeboat stations in total. Yearly they have about 1700 distress calls.
The station in Egmond aan Zee exists since 1824. Currently they have 27 volunteers who are able to go out to sea with their lifeboat named 'Adriaan Hendrik'.
