It would have been the marina's wiring that was wired with the hot and neutral reversed. Your panel reverse polarity light is wired between the incoming neutral and ground connections. These should not show a voltage. But if the hot and neutral incoming are reversed the reverse polarity light is then connected between hot and ground, which would measure 115 volts or so.
