Aries Fleet now offers a Harbor Tour in your own boat. One to two people per boat. The guide is in his own boat and you follow his lead. In our trip, there was one other boat besides us. The Guide communicates by radio. Let me tell you, it was a blast. The tour lasted 2 hours and we went from the El Cid Marina down to stone island and back. We went around bird and deer islands. We had some smooth calm sailing and some adventurous "perfect storm" waves. This has to be one of the best tours on the water. Tired of the booze cruises and sunset cruises where people get stupidly drunk-try this one. My husband has knowledge of driving a boat but the other boater did not and he did fine. He was a lot younger than us and he said when we were finished this one heck of a great trip, we, of course, had to agree with him.
