About us

Islander Charters, Inc. is a family owned business based out of San Diego, CA. We provide Great White Shark Cage Dives servicing Baja California at the famous Guadalupe Islands.  We provide these experiences aboard our vessel an M/V Islander; she’s an 88′ San Diego based long-range charter boat.

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 Captain Ryan Heiser, as well as Divemaster Jimi Partington.

The Islander is 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 thirteen years, we have safely and successfully led over 10,000 people on voyages into Mexican waters for our Great White Shark Cage Dives. Our love for the water gives us a unique perspective of the ocean’s complexities from not only above the water, but from beneath it as well. We offer cutting edge adventure at its peak, focused on the finest the Pacific has to offer.

Our trips are comfortable and accommodating as we limit our passenger loads to roughly half of what our vessels 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 crew with a 100% success rate and a 100% safety record.
