With us, you’ll learn to love and respect the Ocean even more

Conscious of human impact on wildlife, we’ve sworn to do everything we can to protect what we call our second home – the ocean – by implementing the best possible practices in all of our Lanai Cathedral diving trips.

That’s why you won’t find any single-use plastic bottles on our boat. Instead, we’ll provide you with a reusable bottle made of recycled plastic, for you to use during our trip and keep as a souvenir once the excursion is over.

It’s guaranteed. With us, you’ll have the best Lanai Cathedral dive on Maui while causing minimum disturbance to the beautiful nature of Hawaii.

Dive tour at Molokini Crater Back Wall and Carthaginian Wreck

Our first dive will be at Molokini, a partially submerged, crescent shaped, volcanic crater just off the coast of South Maui.  A Protected Marine Preserve, Molokini is home to over 260 marine animals and thriving corals underwater as well as rare birds above the surface.

The crater itself is made entirely of rock so the water surrounding it remains relatively undisturbed by sand and sediment, resulting in year-round visibility of 150 feet plus. The abundance of marine life, pristine waters, and proximity to Maui make Molokini a premier diving destination and one of our favorite boat dives.

During our surface interval we will travel back towards Lahaina and do our second dive at the Carthaginian, a semi penetrable wreck that rests at 100 feet near the harbor. The Carthaginian is a haven for white tip reef sharks, frog fish, eels, and more. 

Eagle rays, dolphins, and whales (when they are in season) are frequently seen swimming past the wreck in the blue. Guests are regularly treated by visits from the Atlantis Submarine as well.

About Molokini Crater Back Wall and Carthaginian Wreck

Our 2 Tank Back Wall and Carthaginian Dive is a world class wall,  drift, and wreck dive for advanced divers.  Many snorkel and SCUBA operators spend all their time inside the crater, but we believe and think you’ll agree, that Molokini’s Back Wall is one of the best dives in the world.  We’ve paired the Back Wall with the Carthaginian Wreck, a deep wreck that always thrills.

Molokini Crater Back Wall

There is tons of life on the wall itself.  You can expect to find cool nudis, pipefish, and endemic reef fish.  But it’s important to look into the blue too as this site is one of the best places for pelagics in Maui County.  We’ve been known to see whale sharks, mantas, tiger sharks, reef sharks, and dolphins on our dives. 

During whale watching season on Maui (from December – May) you’ll dive to the soundtrack of whale song as it echoes off the crater.   The site bottoms out at around 300 feet, but we will stick to a maximum depth of 100 feet for our dive. 

Carthaginian Wreck

Just a short distance off Maui’s shore, under the stunning Pacific blue water, lies a slice of history.  The Carth, as it is affectionately called, is a  replica of an old whaling ship.  It was docked for years in Lahaina harbor before being sunk to create a semi-penetrable wreck. The Carthaginian is a haven for white tip reef sharks, frog fish, eels, and more.  

Eagle rays, dolphins, and whales (when they are in season) are frequently seen swimming past the wreck in the blue. Guests are regularly treated by visits from the Atlantis Submarine as well.

I had a great time diving with Dive Maui last week. I did a 2 tank dive just south of Lanai. Our guide Dom made sure to point out cool things, including lobsters, a reef shark and a large snail eating a sea anemone.

Best dive ever. Nine divers, 4 staff, two in the water, means better service than a 5 star restuarant. Courteous, competent, friendly. They know their stuff, love to pass on their knowledge, and just care while still having fun. Oh, and a hundred dolphins frolicked through our dive group at Cathedral!

Great operation for divers.

No cattle boat feel, wonderfully personal and no setting of 40 minute bottom times. If you love to boat dive, this is your place while diving the west side of Maui, Lanai and Molokai.

We did 2 tank lanai cathedral dive in Feb 2020. Professional staff and good quality equipment. Dives were adjusted to the level of divers, their experience and physiological capabilities. Great atmosphere and tasty snacks on ship!
