About Us


The boat South Seas II has been plying the waters of the leeward coast of Oahu for over 20 years taking thousands of divers out to Oahu’s favorite snorkel and dive destinations! The South Seas II is the only dive boat in operation on the west side of Oahu.  We have the capability to take you to many rarely visited dive sites in Oahu to experience the unique topography of this volcanic island.

Dr. Matthew Zimmerman purchased the business, and its coveted permit to operate on the west coast, in 2017.  Since the pandemic, the focus has changed to small group snorkeling tours and private charters.  Being close to the exclusive resorts in Ko Olina, we have created ocean adventures to suit a diverse group of guests including families of all ages, couples, and group vacationers.  However, those in the know will make the longer drive from Waikiki to ply the calmer waters of the leeward coast of Oahu.

Dolphin Divers operates on the west coast of Oahu only.  It is part of a larger water sport group that includes Snorkel with Turtles in East Oahu, Island Divers Hawaii is East Oahu and Honolulu Scuba Company near downtown Honolulu.  We have experience, and we know how to take care of people.  We’d love to do that for you!


We follow guidelines of the Coral Reef Alliance, to promote coral reef health around the Hawaiian islands. That includes sustainable practices such as no touching coral and encouraging our guests to be conscience of the sunscreen they are wearing while enjoying the waters of Oahu. We deliver exceptional customer service, safety, and Ko olina ocean adventures unique to the west side of Oahu.

Oahu Dolphin Divers respect the ocean and the ecosystem, and this is why we follow guidelines to protect all marine mammals and the marine environment in which they live.

Join Us for the best Ko olina ocean adventures and experience the secret coast of west Oahu!
