This website (since 2003) is renovated completely. Beside a change of platform the content is changed due to new thoughts about a better presentation of the aspects of rips.
The popular chapter with information about under-cooling is disappeared. In stead of this a lot of pictures to clarify the different subjects are implemented. The riprap, an experimental rip current prediction system for some parts of the Dutch coast will be active this summer again.
I hope this website will give you enough information so you can swim safely at our nice Dutch coasts.
