Section E.9: Why starboard side islands?
Why are aircraft carrier islands always on the starboard side? There are several reasons. Initially the island was placed on the starboard side because early (propeller) aircraft turned to the left more easily (an effect of engine torque). Obviously such an aircraft can execute a wave-off to the left more easily, so the island was put to starboard to be out of the way. There may also be other, minor contributing factors. Once the starboard side position was established and a few carriers were built in that configuration, it became difficult to change. Pilots used to landing with the island to their right would be confused on a ship with the island on the other side. There was nothing to be gained by moving the island, so it stayed in the same place. Once angled decks were introduced this became even more important, since the deck angle would have to be changed to move the island. There were, however, two carriers with their islands to port. The Japanese Akagi and Hiryu were fitted with
