Securing funding is a recurrent problem for underwater archaeological projects. It is a stumbling block over which naïvely planned operations come to grief. The result may be major damage to the heritage affected, without this being offset by project results. In view of the fragile nature of underwater cultural heritage and its nature as a public resource, this is indefensible. An adequate funding base should be assured in advance of any activity. No less than three Rules of the Annex address this issue.
