The 45 minute trip out (7 miles) and another 45 min back left about 30 minutes to troll over the reef. The day and trip were nice. But, don't expect to see beautiful fish, plants, and coral. We saw some small fish and a few plants. Everything was in dull shades of green and grey. During the viewing, the host pointed out things and talked, which was informative. For me the trip was decent, but I can see how others would find it disappointing.
