I've bought an old boat currently listed on your database as 'Coralita'. I have renamed it 'Seren' and registered it on the Great Ouse, though it retains its original BW reg plate (60509). I've got some more info about it, the engine type for example currently 'NA' is a Perkins 100 series. Is there any place for owners to update your database?

We don't allow editing of the data - just because it would be impossible for us to validate that person X is actually the registered owner of boat Y. The updated details should come through in the next update from the Navigation authority.
