Diagram for USCG Navigation General: Which statement concerning the chartlet in illustration D010NG below is true?...
A Maury Lightship swings about her anchor on a circle with a 21-meter diameter.
B There is a 12-meter deep hole inside the 5-meter curve just west of Beito Island.
C The position of the lightship is indicated by the center of the star on the symbol's mast.
D The sunken wreck southwest of Beito Island shows the hull or superstructure above the sounding datum.
AI Explanation

The correct answer is D) The sunken wreck southwest of Beito Island shows the hull or superstructure above the sounding datum. This is correct because the chartlet indicates a sunken wreck symbol southwest of Beito Island, which implies that a portion of the wreck is visible above the sounding datum (the reference water level used for the depth soundings shown on the chart). The other options are incorrect because: A) the chartlet does not provide information about the Maury Lightship's swing circle diameter, B) there is no 12-meter deep hole indicated near Beito Island, and C) the position of the lightship is indicated by the center of the star symbol, not the mast.
