Once we got a great kama’aina rate & took the submarine tour in Lahaina. It was interesting but having scuba dived many times in Maui the sub wasn’t as scenic for me. And once below about 40’ colors fade out without artificial lights. They take passengers by boat to the sub offshore to board it. Since I went they have submerged the old brig Carthaginian that was a fixture at the Lahaina Harbor in front of the Pioneer Inn.
