Why carrier islands stayed on the starboard side

Why do modern aircraft carriers not place the island on the port side instead of starboard?

Past trials showed more aircraft striking or approaching the island dangerously, and pilot-control tendencies still make the starboard arrangement safer even in the jet era.

Attempts to use port-side carrier islands produced more aircraft accidents involving the island structure. The problem was greater with propeller aircraft. Jets reduce the effect, but the explanation still points to aircraft arrangements and pilots' control tendencies. Accident experience therefore supports retaining the starboard layout.
