I have sold my boat, what actions should I take?

This depends on your specific situation.

The boat already has a harbour fee sticker which I paid for

Have you already paid for the harbour fee sticker? Then the new owner does not have to pay anything. Transfer the harbour fee sticker to the new owner’s name. You need to do this together with the previous owner. Please send an email to bhg@waternet.nl with the harbour fee sticker number and the name and address of the new owner.

Please discuss with the previous owner whether he/she will pay you part of the harbour sticker fee related to the remaining months of the year.

The boat already has a harbour fee sticker though I did not pay for it

Please deregister your boat. The new owner should apply for a new harbour fee sticker.

The boat does not yet have a harbour fee sticker

You do not have to take any action. The new owner should apply for a new harbour fee sticker.
