If you want a simple and peasant 1/1/2 hour sunset cruise with just the beauty of the water surrounding Waikiki and Diamond Head, this is the cruise for you. Curtiss and Tyler, the captain and first mate, were wonderful navigators and great hosts. They gave you information of the area without trying to be comedians. They were competent and pleasant.
This is a small catamaran. There only were a about 13 passengers on our trip and the boat could not hold more than about 20-25. This is not a "booze cruise" although you are welcome to bring your own drinks aboard. This is not a loud party passage, even though every one seemed to have a good time and all ages were represented from teens to seniors.
I have two suggestions. It would be a lot more comfortable if cushions were provided on the otherwise very hard seats. Also make sure, if you go on the Sunset Cruise that it is 1 1/2 ours as advertised. (When we got there, we were told the cruise only was going to be one hour.) When we said that we were told it was to be an 1 1/2 hour cruise, they immediately honored that longer time.
An added benefit of this tour is that is significantly less than some of the other tours given for the same length of time.
Just go. You will have a nice experience.
