Question Best Way to Get to Oia from Santorini's Old Port in June?

I'm planning a trip to Santorini in June and want to visit Oia. I'm arriving at the Old Port and prefer not to use cruise ship excursions. Does anyone have recommendations for getting to Oia by boat? I'm looking for options that are reliable and offer a good experience. Any tips on what to expect or how to book would be really helpful!
