We've read lots of great boat trips review that all seem to be for snorkeling. We're seniors and unfortunately don;t snorkel, so we'd like a quiet relaxing two-hour-ish sailboat trip to see scenery, either in the daytime or at sunset. We found a great one on Maui, but would love suggestions for something similar on the Big Island. (P.S. If you know of similar trips on Kuaui, that would be a bonus. Thank you!!
