Aichi E13A1 at Lahaina Anchorage

Scout 1 was catapaulted from the "Tone" at 0530 HST piloted by PO1c (petty officer 1st class) Yoichi Takahashi. Seated behind him was observer PO Ryozo Narukawa and manning the rear gun and radio was PO2c Nobuo Oku.

If any ships were present, observer Narukawa would have plotted them on the map shown below. Translations and interpretations are overprinted in blue. Radioman Oku would have then reported the locations in the format shown.

The Katakana characters for the sectors are in the order that they are taught in school. Starting from 0 degrees and going counterclockwise 90 degrees are "ka, ki, ku, ke, ko, sa, shi, su and se". The character "so" is skipped. Starting from -90(270) degrees to 180 degrees are "ta, chi, tsu, te, to, na, ni, nu and ne". The character "no" is skipped. Continuing from 180 degrees to the coast are "ha, hi, fu, and he".

The characters for the annuli (area between arcs) may at first glance appear random but if they are interpreted as the first syllable of a word, they are in numerical order from the origin of the graph (see table below).

Lahaina anchorage was last used by the U.S. Navy on a large scale on their annual fleet excercise of 1940 called Fleet Problem XXI.
