Port Mary (10°50'S., 162°27'E.), on the W side of Santa Ana Island, is formed by a break in the fringing reef and a slight indentation in the coast. The entrance is 0.2 mile wide between the reefs on either side, but its navigable width is reduced to 228m by some detached shoals which extend 145m N from the reef on the S side. Caution is advised as the reefs have been reported to be extending, and also reported to dry (1985).
