I just got back from a couple weeks on Kauai (family business), and I saw there were a dozen or so cats on the beach at Hanalei Bay, but most looked like they hadn't been touched in a while. There were three or four Prindle 18's which did look well cared for, and an older Getaway which seemed well used. This time of year the big waves shift to the north side, so even Hanalei had 10 foot breakers at the beach. Poipu might be better through the winter months, but I didn't make it down there this trip. I also saw an AquaCat in a yard by the Kapaa beach park that looked ready to go, but never saw it out. I think you need to be very aware of conditions, currents and reefs around Kauai. Maybe take a few excursion boat rides (or talk to their operators) to scout out the better sailing areas from the water.
