Avi Klapfer is the Israeli co-founder of the Undersea Hunter Group – the preeminent Cocos Island liveaboard operator since 1990. Born and raised in the northern part of Israel, Klapfer completed his military service as a naval officer and took a job as a dive boat captain on the Red Sea. There, he fixed up a sailboat and navigated around the world with Orly, his soon-to-be-wife, and Yosy Naaman, who is now his business partner. To Klapfer, one of the most important elements in protecting Cocos Island is showing the world its novelty through photography and video.
