Definitely true, permit by notification form must be completed. Also it is not acceptable to tie a jet dock to an existing mooring as moorings are not supposed to be used for PWC anyhow. In the new mooring applications PWC cannot be listed as acceptable boats for the mooring application process when trying to prove the need for the mooring that you are requesting.
