My standards are pretty high. I'm comparing the islands to the Caribe, Costa Rica, Seychelles. Ten years ago the Florida Keys were on my list, but no more due to ever increasing fishing pressure. My method of fishing is sightcasting and primarily on the fly. I think Hawaii rates high in all three categories, but not tops in any. Still on our short list but I would probably have a performance daysailor rather than cruiser since the islands are farther apart and harbors are limited. I should add low crime and great people make the islands a very special place and not as expensive as many think. You are correct we were on Oahu this trip. Big Island on the next trip.
