Sanctuary staff work to actively promote uses of sanctuary resources that are compatible with sanctuary resource protection; in fact, all National Marine Sanctuaries promote multiple uses.

Access to sanctuary shipwrecks is not restricted. The range of depth of the shipwrecks appeals to a variety of diver skill levels and also provides recreational opportunities for non-divers.
