Awesome, one of our NZ highlights so far
The trip was really cool. Captain Ray was very friendly told us a lot of interesting stories about himself, the history of the boat and Akaroa. He also gave us some "seasickness" medicine that seemed to help, since my girlfriend tends to get seasick on boats like this. It is cool that you can go on the water with so few people. (In the beginning he wanted to go with just the two of us, however, in the last minute two more women joined the trip. But its nice that he wouldn't have canceled or shifted the trip with only two people on board). We got to steer the boat on the trip, which was a lot of fun. Also, we saw a lot of hector dolphins and even (which is very rare, as he explaints) three hector dolphin babies! Ray was very knowledgeable about wildlife, but he also told one or the other story which was very silly and not entirely true but very entertaining nonetheless :)
Just do it, you won't regret!
