My wife and I rode in the Na Hoku I catamaran directly in front of the outrigger hotel. I spoke with the asian lady who stands with a clipboard (forgot her name, but very friendly) She takes the reservations, book early if you want to take a cruise they have about 4-5 a day. Free drinks (coors and PBR beer, mai tais). Cost is $30 per person. in my opinion worth every cent.. i dont care much for the drinks, but i did enjoy a few which was a nice compliment to the breathtaking views, sites and sunset i observed.. not to mention all the great foto op's. The ship was packed, but the majority seemed to be couples looking for a romantic sunset cruise, there was however a group of late 20's who were loud, obnoxious and stupid.. their screaming and antics amongst eachother were annoying, but didnt take anything away from my cruise.. Captain "rabbit" and his crew were fantastic, very friendly, played good music, made the trip fun and memorable. Becareful when first leaving shore when the waves start crashin the water starts a splashin. Don't sit in the front if you dont want to get wet.
