Talk about moorings only concern:
- moorings for permanently and leagal living aboard;
- daily moorings for passenger ships.

The status of moorings
The status of moorings is quite diverse. Moorings are controlled by local authorities, foundations, domains, district councils, Ministry of waterways, private persons etc. It is not possible to describe a clear policy in brief.
Concerning the 'so loved by the Dutch' deductibility of mortgage interest, the treasury has no other condition than that a mooring needs to have a durable connection with the quay and is used as the 'first residence' of the owner. Most financers make it more difficult and prefer that the mooring needs to be 'transferable by the government'. If not, then financers consider that, as a sign of care-duty towards clients, the mooring can be lost. If that happend the bank considers that the deductibility of mortgage interest will most likely be lost as well.

Live aboards suitable for museum harbours
In the category 'Live aboards suitable for museum harbours', you will find ships with - or with the possibility for -  a mooring in a museum- or historical harbour.  The transfrability of these moorings is not quaranteed normally. Each museum harbour handles her own rules. The policy usually aimed at a collection of various types of ships.
Because many museum harbours only want to consider the continuation of a mooring after the owner has proved that he is the actual owner, the financing of these ships is a somewhat difficult.
Ships with a so called monumental status by the Federation Old Dutch Ships (FONV) do have a chance for a mooring in a museum harbour anyhow.
