All the reviews I've read are very positive about The Scuba Shack so I think our experience was not usual. My two nieces and sister and I went to Kihei Maui for a wonderful vacation in which we experienced many "first experiences" - Snorkeling was one of ours and we took a trip with Charlie and crew to Molikini crater. We had a group of about 15 so it was crowded on the boat. Only 5 of us snorkeled. The boat is very fast and that was great as we arrived at our destinations quickly. We also went to Turtle town. The population of fish to see was actually much greater at the protected preserve so that was a bit of a disappointment but we had a beautiful day and did enjoy seeing turtles at turtle town which was a thrill. What I did not like was that Charlie catered to the scuba divers by anchoring way out in the open waters of Molikini crater. The 5 of us snorkelers were directed to follow the reef that juts out from the far right corner of the crater and then swim over it to the crater. We were on our own and one of my nieces had a hammerhead and reef shark next to her... one swam to the side and one below her. My other niece and I saw another shark as we swam in the open waters a couple of hundred feet from the crater! We were not told how to react if we saw one so we were all scared. I know the tourist industry doesn't want to make a big deal about the sharks but after this experience I read that there had indeed been shark attacks in the area a month before. I know there are not many shark attacks (six the year previous) but for NEW snorkelers I would have preferred a safer experience for us. I noticed all the other boats out with snorkelers stayed near - and some even were in the water with them. On the way back the captain showed off his boat driving skills by doing circles and advertising the other businesses he ran. He was also too attentive to one of the women on the boat who he brought as a date. This was the experience we had and we would not go again with this business on a return trip to Maui. We would definitely go in the water again but in an environment in which we felt safe and cared for!
