Mahi Wreck
Dive 60–95 ft off Oʻahu’s West Coast.
Intermediate to advanced divers — explore a mesmerizing wreck alive with marine life.
Quick Facts
📍 Location: Off Oʻahu’s west coast
🌊 Depth: 60 to 95 ft
🔦 Visibility: Up to 100 ft
🎯 Experience Level: Intermediate to advanced
🐟 Marine Life: Eagle rays, pufferfish, octopus, whitetip reef sharks, nudibranchs
The Mahi wreck, once a naval minesweeper, lies off the coast of Waiʻanae. Sunk intentionally in 1986 as part of Hawaiʻi’s artificial reef program, the wreck has become a thriving underwater habitat. The collapsed bridge and structural features provide rich exploration zones — without full penetration access — while marine life abounds in the nooks and crevices.
Expect schools of pufferfish, eagle rays gliding overhead, octopus hiding in crevices, and occasional whitetip reef sharks. The mix of history and biodiversity makes Mahi a standout wreck for seasoned divers.
❓FAQs: Mahi Wreck Dive
How deep is the Mahi Wreck?
📏 The Mahi sits in 60 to 95 feet of water. It’s considered a deep dive, recommended for intermediate to advanced divers.
Can I dive the Mahi if I’m a beginner?
🚫 This dive is not recommended for beginners or Discovery Divers. We suggest joining one of our shallow reef dives first — like Makaha Caverns or Star Caves — to build comfort and experience.
What’s the visibility like?

🧰 All basic dive gear is included or available for rent. We recommend bringing a dive light to explore the crevices and structure.
What experience level is required?
🤿 You should be a certified diver with recent experience and good buoyancy control. While not a technical dive, the depth and open-ocean location make it more suitable for confident divers.

🐟 You’ll often see schools of pufferfish, eagle rays, octopus, nudibranchs, and even whitetip reef sharks. The wreck attracts both reef and pelagic species.
Do we enter the wreck?
🚫 No penetration. The Mahi has collapsed areas, making entry unsafe. We stay outside the structure but still enjoy dramatic views, swim-bys, and lots of marine life interaction around the wreck.
