Liveaboards offer a great way to meet like minded people, the freedom of being in the Ocean, far from the problems of modern life and get the taste of adventure in a professionally controlled environment. It is the combination of a cruise and dive vacation with amenities, security and you don't have to lug your dive gear around each time you're going diving. The Kona Aggressor II is Hawaii's only one permanent liveaboard, located on the west coast of the Big Island.
