The experience was poor on a number of levels. 1) Kauai Sea Tours booked too many people for the size of the boat. The seating was supposed to be three people per bench, but at best that would seat about 30 passengers. There were 36 or more on our tour. By the time it was our turn to board, there were no places for our family to sit close to one another, and people had to sit back on the sides of the boat or stand near the bridge area. Making matters worse, a number of larger guests were boarded first, taking more than their allotted space, and the crew made no effort to ask them to try and accommodate others.
2) We got off to a rough start as the crew had trouble with one of the engines and we sat at the pier for 20+ minutes while they got it running....better there than out to see, but a frustrating wait. 3) The boat is too small for the conditions/theme of the tour. This isn't billed as a "high adventure" tour...we were expecting a relaxing sunset tour with dinner/drinks. Even in mild seas, we were jostled and drenched pretty much continuously for the first 2/3 of the trip, until we turned back to port. Numerous participants were seasick and miserable as it was a rough ride the whole way. Yes, the tour states "plan on getting wet" but it was pretty much non-stop for the majority of the trip and there was no place on the small boat to seek shelter.
4) "Dinner" was a paltry serving of average pork or chicken over rice, and a tiny salad. Pretty much minimum effort on the food.
5) On the bright side the three crew members were genuinely nice and did their best despite the less than ideal conditions, and of course the scenery is spectacular. I thought about giving it a second star just because the guys were good, but the overall experience doesn't warrant any more credit.
My advice is to spend your money elsewhere....the larger catamarans that were on the same route were much more stable, and the guests ride much higher off the water, so they were not soaked non-stop, and are much more relaxing trips.
