About us

Islander Charters, Inc. is an American family owned business based out of San Diego, California. We provide Great White Shark Cage Dives servicing Baja California, Mexico at Guadalupe Island – the mecca for Great White Sharks.

We take pride in giving you the best possible customer service from your initial contact with owner Juliet Conniff in the office, to your time aboard the boat with each of our crew members. Each voyage is run by Captain/Owner John Conniff or one of our other highly trained captains. International shark expert and lead Divemaster Jimi Partington provides  guests with commentary on his ocean experiences around the world.

All trips are run aboard our vessel, M/V Islander. She’s an 88′ long-range charter boat based in San Diego, California. The Islander is an American flagged vessel, regulated, certified, safeguarded, and annually inspected by the United States Coast Guard. All of our employees take part in the USCG drug testing program as well.

In the last seventeen seasons, we have safely and successfully led almost 20,000 people on voyages into Mexican waters. Our love for being on the water gives us a unique perspective of the ocean’s complexities from both above the water and beneath it. We offer cutting edge adventure at its peak, focused on the finest Isla Guadalupe provides.

Our trips are comfortable and accommodating as we limit our passenger loads to roughly half of what our vessel can actually carry. This is done to offer unique and personal experiences. We guarantee you’ll see Great White Sharks! We’re an award winning exceptional operation with a 100% success rate and a 100% safety record.
