If a wreck is older than 1850 or deemed to be significant by SAHRA, a suitably qualified maritime archaeologist, approved by SAHRA and preferably employed at a recognised institution, must be included as a full member of the team: Provided that if a maritime archaeologist is not available, a suitably qualified approved archaeologist may be included in the team, on condition that he/she remain in regular contact with SAHRA during the work. If there is no archaeologist available at the collaborating institution, arrangements for the inclusion of a suitable archaeologist on the team must be made in consultation with SAHRA.
